Determining the Bolt Pattern
The first number in the bolt pattern is the number of bolt holes. The second number denotes the diameter, in inches, of the circle on which the bolt holes sit.
On wheels with an even number of bolt holes, measure from the center of one bolt hole to the center of the hole directly across from it. (Example: 8 on 6-1/2 means 8 bolt holes with 6-1/2" from the center of one hole to the center of another on the opposite side.)
To determine the bolt-circle diameter on wheels with an odd number of bolt holes, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from the first. (Example: 5 on 4-1/2 means 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolt holes.)
Measuring the distance (D) from the center of one bolt hole on the wheel to the center of a bolt hole right next to it can also help to determine the bolt pattern.

Today were going to install part number TRBK10E01 from TruRyde. This is their Electric Trailer Brake for Left Hand Side. Were going to start off our install with the idler hub already removed from the trailer. This trailer previously did not have brakes so were going to add brakes to the trailer. Now if we add brakes to this trailer axle due to the fact that it has a brake flange already installed located here. The brake is very to install, Ill just make sure the mag is pointing at the bottom.
Now the studs are already built into the backing plate so all weve got to do is add lock washers and nuts. Lock washers will be 5-8 and the nuts will be part number 6-17. With our brake assembly installed on the axle now well go ahead and install the hub. Were using part number 84546UC3-EZ. First off, well apply a little bit of grease to the inside of the races and the bearings.
Then well go ahead and assemble the back bearing and seal. Then well do the same thing for the front bearing and race and apply a little bit of grease. Well go ahead and install the hub. Well add the washer and a nut and tighten it down as needed to make sure we have enough free play in the hub. Then well use a grease gun to fill up our hub.
When we fill up a hub it will also pack the bearings at the same time because the grease has to go through the bearings to get through the hub to the other side. With the hub packed, well go ahead and double check the adjustment for the hub then well go ahead and install the locking cage for the nut. Then well go ahead and install the dust cover. With our hub fully installed well go back to the backing plate and what well do is go ahead and adjust it now. Well take the adjuster and tighten up the drum until it stops moving then well back it off 10 clicks.
We should have a slight dragging on the hub when were done. Now we can go ahead and start hooking for wires for the backing plate. Now we ran the length of the wire from one side to the other and then up to the top. Were using part number 12-2-1. Now on the hub were working on well go ahead and cut the wire in half and make our connections. When we connect our wires from the backing plate to our new wire in a gray cable, it doesnt matter which wire goes to where, as long as you make sure that one of the wires in the gray cable goes ground and everyone goes to brake controller outlet. Theres a variety of ways in making a connection series, you can use wire nuts or a crimp style connector. For our connections made at the left side, well repeat the same process for the right hand side. With that that will cover the installation of part number TRBK10E01.

Fast shipping and top quality parts! Last summer I replaced all four brakes, hubs and bearing sets on my camper with these identical parts, but over-torqued one bearing and experienced an outer bearing failure on one spindle - almost lost the wheel. This unit is the same as I used previously and will replace the hub that was damaged by the bearing failure. I'm just waiting for warmer weather to install it - I won't be as aggressive on tightening the bearing this time. 116262

I ordered a complete electric brake setup for my 6x12 Haulmark trailer and Timbren springs for my Chevy Silverado 1500. Etrailer is great to work with and at this point I have no reason to buy from anyone else!! The brakes are all Dexter parts which is what I wanted. They were very easy to install on the trailer with a bit of help from the etrailer video. The brakes work great and give me a much better feeling about stopping the trailer in a emergency situation and is much easier on my truck brakes. The Timbren springs springs were easy to install after I realized that the installation is not correct for a 2004 Silverado but could be right for a 2011. The springs work very well as long as I have a fair amount of weight on the truck or pulling a trailer with at least 200lbs of tongue wt. When the truck only has 3 or 400 lbs in it which is normal with a cap and bed slide, it rides quite a bit rougher than without the Timbrens. I think air bags would have been a better decision with varying weight loads 47572
Got this with a 10 inch trailer brake. Everything was as expected. I had to buy a couple nylock nuts from Menards. They are 7/16 by 40 pitch. Which is a fine thread. 220256
Everything arrived in good shape. Haven't installed do to weather. Was missing one plastic wire fastener on one of the breaks. On rechecking the web page I see that the nuts to secure the break to the trailer were to be purchased separately, had I noticed that I would have included it with my order. No problem was able to purchase 8 nuts and washers for $2.00 at a local nut and bolt dealer. Appreciate your help with my purchase and will deal with you when I need more items for my utility trailers or camping trailer. 178223
I bought 4 of these to replace all my brake system parts. They came with the races installed and were very easy to assemble and install. Nuts come with them. BE SURE TO SAVE YOUR GREASE CAPS FOR THE ONES THAT CAME MINE ARE JUNK AND DO NOT FIT. Time will tell the quality but at this time I have told my friends to buy these for the price is right. There is not a place to Review the ETrailer service. I had to send several emails to get any help. Nothing was done about the grease caps and I was finely sent 4 plastic adjusted plugs, which I returned so they could see the poor quality for themselves. Service left me sour. order the right parts and double check to be sure and return any junk. Service rating POOR. 222618
installed brakes on my 97 Rogue boat trailer. E-Trailer had everything I needed for the job. Trailer already had the 4-hole mounting plate for the backing plate. It was all bolt on, brakes work great. I have bought quite a few items from them over the past few years, including an axle assy with brakes for another boat trailer, 2 brake controllers and also a trailer hitch for our older Lexus suv. I am very satisfied with there service and quality of there merchandise. 276795

Great help from Jennifer on etrailer. I chose the actual Dexter Hub and brakes. These are really top quality. I expressed concern regarding Chinese bearings as that has been a problem from other vendors. I was assured that while these were from China, they have supplied these for years with virtually no problems. Upon arrival, which was extremely fast(!!), I examined the bearings immediately. They do look and feel great and are a recognizable brand. The bearings that I had received from a competitor were pure junk! I will update later after a year or so of use. So far, I would recommend etrailer to everybody. 285616

Ordered online and etrailer responded within minutes to let me know the part I ordered was not in stock, but they had another brand of the same part available, which I agreed and with paid 3-5 shipping received package in 2 business days. Installed the same night and all went well. Thanks etrailer for excellent customer service. Will definitely look to you first for additional needs for our trailers. 258998

Just what you'd expect. The EZ-lube kit also included the solid center grease cap. 227132

I am very happy with the products I purchased and the service I've received from etrailer. I jump for joy when I see the "made in america" label on products. At first I was just going to buy wheel bearings but when I saw how reasonable it was to put a set of brakes on my 5 X 8 covered trailer that I use to carry my motorcycle (Harley Bagger) I couldn't resist. Since the initial purchase I have made other purchases from etrailer with the same excellent customer service and product quality. You get what you pay for! Thank you etrailer. PS: I love the instructional videos also. 39526
I have ordered products before and service has been great. I like that a name of contact person is given, makes and online experience much better. This past order was for drums and bearings for my boat trailer. As usual they came earlier than I expected. Everything was there. Only one complaint was that one of the drums had a considerable amount of surface rust. I was able to remove it with emery cloth and every thing else seemed OK. Perhaps the person picking parts from storage should be given better instructions as to how to inspect the product before delivery. 220505
Worked as they should fit as described. 231231

Got boxes last week, as promised fast delivery. Bought the brake drum assemblies and the complete electric brake systems for my old travel trailer. I was going to install but I'm having the axles flipped sooooo, I'm having that shop do them. Reason- brakes 1st then have the axles flipped, the brakes would be upside down. Etrailer's websight was great. It was late when I ordered and had some questions. I went to the question section and my ? was answered. Thanks guys for great prices and the items I needed. 177541
This is a Dexter OEM hub assembly, so it was manufactured per Dexter spec's and quality control. 142719
by: Robert M.01/31/2016
The drum/hub comes with everything needed including two types of bearing caps. One with a rubber plug and a standard metal cap, this helps if you have a grease fitting on your axle. Especially love the packaging eTrailer uses, product arrived without any damage. Thanks eTrailer! 236665
by: Everett w.04/08/2015
Product is everything you see and more. Everything fit just like it came off the axle. The numbers in the ETrailer on line catalog and the numbers on the old parts were the same. The brake backing plates and brake assemblies saved hours of frustrating work to put together. An hours work with a coffee break I was done. ETrailer has good instruction and helpful videos to go with these products. Thanks The shipping order arrived within the time ETrailer said it would. 184095
by: Tim B07/26/2013
This seems like a good product and it was definitely a good price. Everything went together fine. Only problem was that I was missing the lug nuts on one of the drums. The packaging was a little suspect as well but it didn't affect this product. (Two 30 lb drums in a cardboard box playing pinball with two backing plate assemblies half way across the country) I got everything I needed and didn't spend a small fortune...good enough. 91660

Thank you Rose G. for making the buying experience easy. You answered all my questions and sent all the information I needed. The parts arrived on time and are exactly what I ordered.

Great price, fast ship. Ordered on Sat. Night and received on Tues. morning. Product is great quality. Only suggestion I would make is that they should include nuts for the backing plates. ( I ordered those as well) Anyone that is ordering these is usually replacing old rusty ones and can't reuse the old nuts. Other than that misunderstanding everything was great. Would definitely order from etrailer.com again. 29515

Received all the parts to rebuild my travel trailer brakes in a short time. Everything from lug nuts, heat shrink splices, drums, bearings, seals, brake backing plates with complete brake assemblies. All in two boxes, albeit two heavy boxes... Total rebuild time from bare axles to tires on and torqued, about 2.5-3 hours. Everything I needed was there. Thanks to Sam G. for the great customer service. 339817
by: Kevin L09/12/2013
Overall , no complaints about the product for the price . Nice hubs but a bit cheap on the bearings . Everything fit fine and works as it should . My only and biggest complaint is the packaging - products this heavy need to be wrapped in cardboard before boxing - the box was severely damaged in transit and I had to replace 3 of the new lug nuts . Otherwise, great service and price can't be beat . 99559
by: Scott D.06/14/2014
Good price and great hardware. I replaced the cheaper bearings with ones from the local auto parts store for an additional $15.00 per hub, but having good bearings to match the quality of the hubs was important. I used these with the TruRyde Electric Brake Assemblies. Went on easy and with the help of the videos on etrailer.com, I felt very confident that the job was done right. 135579
by: Keith G.03/31/2015
Arrived as advertised. Put these on my travel trailer in no time. Just pack the bearings and bolt them on. The lug nuts didn't work with my wheel, as it needs a deeper/longer nut to stick out far enough to get a socket on it, as the lugs are recessed in the wheel. Unlike the picture, a second dust cap without the rubber insert to get to the zerk fitting was included as well. 181783
Excellent quality and direct fit. Ordering complete backing plates made the install very easy by removing the four bolts on the back of the old plate and installing the new plate. Used a little brake cleaner on the drum and assembled the bearings; and the install was complete. E-Z lube the axle and bearing and done. Couldn't of been a better install and replacement. 26128

I have an '06 Dively car trailer and bought the 10" electric brake assembly 23-26, 23-27/Hub drum assembly 84546U3-EZ/ and Hopkins 12 volt battery. The parts came quick (as promised), they were packed well, very good quality. Everything bolted on with no problems. Mike from customer service was very helpful. I would highly recommend! FREE SHIPPING TOO! Jim 53637

I had replaced all four of the hubs on my travel trailer and one blew out on a recent trip from Orlando back to Miami Florida. They were all inspected and had the proper amount of grease before the road trip. I was disappointed since they were new and had few miles on them. It may have been defective since the other three are still in tact at this time. 276363
I know that the parts are heavy but the packing of the first order sucked. I didn't see the wires were just about severed during shipment because it looked like they were just thrown in the box. The second order when I received it, the drum was about ready to fall out of the box. However, the salesperson was helpful, and knowledge of product was great. 211847

Just recently started using "etrailer" and have found it to be the best "one stop shop" for all things trailer related. My latest order was a hub and drum kit to carry as a spare. I was happy to find out that it was actually OEM. I love everything about this site. Great products, service, support, pricing and prompt shipping. I am a customer for life. 110422

This product is just a Dexter part. They are what was already on my trailer. The real great thing was the etrailer experience. One of the easiest orders I have ever placed as a "do it yourselfer" The service and advice was first rate and my order was shipped fast and arrived complete. I'm very glad I found etrailer.com to get these parts. 162926
As other reviewers the packing shipping was a little lacking. It probably did some bouncing around. The hub arrived with rust. I has to contact Dexter and send a picture to make sure that it was not an issue. They okayed it because it did not get into the race. Bearings seemed to be on the cheep side. Guess you get what you pay for.... 156233

I ordered a hub on a sunday. The order was filled and shipped on that same day and I received it within 5 days. They told me when it would be delivered and it was. I am very pleased with the service as well as the product. I would definitely recommend etrailer to friends and anyone else. Great service, great folks! 18413
by: Chas. S.05/24/2012
Second axle done in as many weeks. If I didn't find etrailer and theses prices, help videos, etc.. I never would have done both axles.The hubs came with everything needed and the bearing races were already seated! Good value, fast shipping. Thanks again etrailer! I can now tow with confidence! 41578

I purchased these products to replace worn out parts on my utility trailer. Parts were delivered quickly and order was complete. The hardest part for me was removing the old parts from the trailer!! Will be ordering parts again for the next trailer. Thanks for the great customer service! 159653
Very pleased with the product. the fit was perfect. what you get for the money is amazing. the only slight drawback is that the bearings don't have any brand or part numbers on them, which leads me to think they may be of lesser quality. Again, what you get for the money is well worth it! 43885
by: A JENNINGS03/06/2015
Everything was flawless and everything fit perfect. Shipping was fast and reasonable. 177272
by: Harry L09/04/2013
Excellent and made in the USA which you can't find anymore. Anyway, not on the trailer yet but looks like a perfect match and definitely need it as the ones on my trailer are completely rusted and definitely wouldn't trust the rusted ones going down the highway. Thanks. 98302
I bought 4 of these to replace all my brake system parts. They came with the races installed and were very easy to assemble and install. Nuts come with them. Time will tell the quality but at this time I have told my friends to buy these for the price is right. 222607
by: Matt A.12/22/2015
Dexter hub and brake plate assembly were delivered as expected (no issues and delivered quickly) although the bearing/seal kit is from China, which was not expected. Also, because of the way the items were packed, the EZ lube cap was dented and unusable. 234025
by: John C06/29/2012
Not installed yet, but everything shipped and arrived as expected. Only bought one side, but will probably get the other side from etrailer soon. Looks like the bearings are made in China, but I doubt anyone else in the world is making them any more. 46261
by: Bob Thomasson06/28/2012
Drum is OK, but the included bearings are very low quality and I won't use them. The price was cheap and cheap bearings were of course what is included. etrailer.com should offer a more expensive option of real bearings (Timken) like other places do. 45952
by: Rich E11/19/2014
Product arrived ahead of schedule and was easily installed. Etrailer videos were very helpful in giving me the confidence to undertake replacing my worn out trailer brakes. The brakes work well and were a good upgrade for my older travel trailer. 161894
This was a replacement for the original units I purchased from e-trailer after I "wasted" the original. These units fit perfectly & work well. I will continue to use this vendor for my trailer parts & supplies. PS- Customer service was excellent! 261334
I bought two brake drums. The packages included everything I needed, bearings, grease caps and lug nuts, just as promised. The drums were a perfect substitution for the old drums. Everything fit as it should. Delivery was very quick and free! 249895
by: Jack H.10/07/2014
This product is great it fit like a glove. I'm in the business of hauling and I received my order quicker than I thought it would take and it got my trailer back on the road and making money. Thank you for your great service and fast delivery. 154972
by: Alan S06/07/2016
These fit great once I determined that the 2200 pound axle used the same stepped spindle as a 3500 pound axles and I received the proper parts. Not all 2200 pound axles work with a 7 inch brake assembly designed for a straight spindle. 258641
The Dexter brakes will go on a Dexter axle for an atv trailer. They are the high quality I expected from Dexter, but they need to be packed better. Thet destroyed the shipping box. But I am pleased with the product and delivery. 141225
Just as advertised. Ordered one day, delivered on 3rd day afterward with free shipping on a pair, along with a pair of brake assemblies. All marked "made in USA". I don't think you will beat their price, or quality, anywhere. 21082
Installed on 2012 Keystone travel trailer The drums were rusted when they arrived. Other drums and rotors I have purchased were coated with a rust preventive. After I cleaned them up they seemed to work as expected. 299646
