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.

• If D = 2-5/8", then the bolt pattern is 5 on 4-1/2"
• If D = 2-3/4", then the bolt pattern is 5 on 4-3/4"
• If D = 3", then the bolt pattern is 5 on 5"
• If D = 3-1/4", then the bolt pattern is 5 on 5-1/2"

## Video Transcript for Trailer Brakes and Wiring Installation

Today we are going to show you how to install brakes on a trailer that does not have existing brakes. It is actually pretty easy to do. It is just very time consuming. There are a couple of things you want to look out for before you start. You want to step behind your trailer, and look behind the existing hub you have. Make sure you have a flange like this on the axle. It is this 4-bolt flange on here; if you have that on your axle you are pretty much home free. This size flange has four bolts. You will see it on 3,500- pound axles like we have here. You also see it on 2,000- pound axles. On a 3,500 -pound one you would probably use a 10- inch drum and on a lighter axle, 2,000 pounds, you probably would use a 7- inch size. Also you notice we have the hub missing. We have to take that off because the hub and drum assembly is all in one piece. It is not like the automotive application. You have to take off the old hub, discard it, and start off fresh.

For this install we are going to install the backing plate. Basically it slides on like so, then it gets bolted onto 4 places. A couple things you might want to take note of is that there is a left and right side to it also an up and down. The magnet always stays pointed toward the ground. And if you did not have a sticker on your brakes that tells you which left and right is, just look for this bow right here. The actuating arm or bow always points to the front of the trailer, so that is a good reference point for you. At this point, let us go ahead and start bolting on our hubs. Works down in a criss cross pattern and make sure you have them evenly tightened. And at this point, you probably want to go ahead and do the same thing for the other side. One thing to note while you are adding the hubs to a trailer - take a look at the spindle. This spindle we have here, for example, we have what is called an EZ Lube spindle. It has a zerk fitting on the end. What happens is grease travels through the middle of the spindle and comes out this hole here. If you have that it is great, but the thing is when you get a new hub you want to make sure what kind of seal it comes with. Most of the hubs will come with a regular single- lip seal. You can see the just one lip right here. It has been around for ages and works great. However if you use this with an EZ Lube Spindle, what happens is grease gets pulled in and applies pressure to this. So what you want to do actually is get what is called a double- lip seal. As you can see here it has a lip on the inside edge here along with the lip on the outside too. Again, this is double protection that keeps grease in and has a little bit extra pressure. You can also tell it is a double- lip seal because you can see a little spring in there. Every double- lip seal out there is going to have that spring in it. So you have an EZ Lube Spindle or double check. Just to be on the safe side, go ahead and order a double- lip seal for your hub. You can see where our hub is sealed right on the edge of the spindle here – I guess you could say it is the bearing or seal surface. This is where you are inside bearing rides right here. [I am going to leave this out for a second.] As you can see here there is the hole where the grease comes out, so it is actually between this seal and this bearing.

We will do our drivers side now, and what we are going to do is install our ground on this part of the frame here. Actually you can do it everanywhere you want, but we are going to hide it back here and make it a little nicer, and then run our ground wire on up to the front. So we will just go ahead and open up the sheath again. We will then split our wire here and put two ring terminals on there. Now, what we did was we ran our wire and mixed it in with the loom up – that makes it look nice and neat. We are going to put our 7- pole connector on next. First you slide on the cover; then you strip these wires and add ring terminals to them so the connector fits inside. Now well go ahead and add our 7-pole connector here. Now, its tempting to do it color for color because you’ve got the red-yellow-green-brown-blue-black on here and they match up to here, but theres actually two different codes. Say, for instance, sometimes red on here is actually left turn, but on the trailer it is actually yellow, and so forth down the line.. The only common ones you have is white for ground wire and white on the trailer, and blue will be used as our black wire. And the black wire, is actually used on here is actually for the 12- volt power lead. We will start off with the ones that match up and that would be the white. Then well go right next door and do our brake wire. And again, on a trailer it is black on this one but its going to be blue on the 7- pole. Left turn on our trailer is yellow, but the left turn on our 7- pole is actually red. We have green here and that’s our running light and on the trailer it is brown. And then green is right turn on our trailer and that is brown on our 7- pole. Next we just go ahead and slipput our connector back in with the little screw. Then were going to fix our loom and were done. And then tighten the screw. With that our install is complete all we have to do is test it.

I got these drums in to replace some old ones. the only thing I miss is the adjustment hole. But being an over cautious tower I inspect my trailer brakes often. Installed yesterday and they worked great. Ordered on a Sunday and received on Tuesday - but I live in the same shipping -zone I believe - got some great LED trailer lights as well.

Wow ! Great prices and fast shipping. Saved a ton. I wish I had found you last year when I had to rebuild my othe Pace Shadow GT Trailer after some 150,000 towing miles. This open trailer has had a tougher life and maybe 50,000 miles. We turned around while working on the trailer and there he was. The local turtle thinks he found a new girlfriend !!LOL Gues he likes your drums. 27884

Simply Exceptional Service! I wanted to make certain I ordered the correct parts to add brakes to a trailer and phoned their sales dept at 7:30 p.m. on a Wednesday evening. I then placed the order online after that. When I arrived home on Thursday the entire order was on my doorstep. And best of all the shipping was free. Great price, great customer service.9675

Good hub/drum assembly. Had a problem after I got them on with my wheel not wanting to fit. Still haven't figured out how a wheel that was on a 5-on-4.5 hub wouldn't fit this hub. The old wheels appeared to be off a car, maybe that was the problem. Just got some new wheels meant for trailers and they fit perfectly. The only other issue I ran into was getting the dust caps on turned out to be a painful process for some reason.88705

To anyone who is putting brakes on a trailer I got a set of electric brakes hubs bearing and seal and cap from e-trailer and everything fit perfect. They even arrived 2 days earlier than I thought. I would recommend e-trailer over anyone else. They have the best quality product for less and made in USA. For me if I need any trailer parts I wouldn't look any more. They have very friendly service and has someone there that not only works in office but understands and knows bearings and when you ask questions knows exactly what you are talking about. I am completely 100% satisfied with their product and service. Jeff Cannedy78324

With only 10days left before a 1,000mi trip with the family travel trailer, I decided to check one of the brakes for wear. To my great dismay the brakes were heavily worn. On last Friday afternoon, etrailer customer service helped me determine what parts would be needed for my application and for a little over \$400, I ordered everything to make completely new again. I received completely assembled electric brakes, new wheel bearings and drums for four wheels. The items were rec'd on the following Wednesday with standard shipping. Wednesday evening I installed all new parts, which all were correct and now I am ready to roll with 6 days to spare. I would strongly recommend etrailer for your trailer needs. 52675

This was the easiest brake job ever! from start to finish, from jacking up, taking off wheels and old hubs, installing backing plates, new bearings and hubs, and wiring took only 1 hour. They work perfectly! Super fast shipping and great customer service! Thank you!50573

I have not yet installed the new hubs/brakes on my trailer. I did open the box and inspect what was shipped. Everything ordered was there and appear to be of good quality. Shipping was fast and I found etrailer prices to be lower than most other internet dealers. Plus other dealers charge for basic shipping (\$30+), making this a very cost effective way to add brakes to my trailer.33768

Purchased 5 lug 4.5 hub and electric break assembly with controller and wiring. The Web site was easy to follow. Video demonstrations gave me enough information to place an order with confidence I was getting the correct parts. They will be installed on a 24 ft open car trailot. Shipping was fast. I would recommend your company to others. I will write a second review when I install parts and take it for a pull to the drag strip this spring.6895

• Will Dexter Hub and Drum Assembly 84546UC3 Fit a Dexter 2,500 Pound Axle
• The bearings included with the Dexter 3,500 pound hub and drum assembly you are looking at are inner bearing L68149 and outer bearing L44649. The inner diameter of L68149 is 1.378 inches. The inside diameter of L44649 is 1.063 inches. These measurements are close to but not the same as 1-3/8 inches or 1-1/16 inches. To measure bearings properly you will need a more precise tool for measuring like a dial caliper. Part # 84546UC3 appears to be the right hub and bearing kit using your measure

• Races Installed on 3500 lb Hub/Drum Assembly Part # 84546UC3
• The 3500 lb Hub/Drum Assembly, part # 84546UC3, is shipped with the races installed in the hub. The bearings, seal, and dust cap are also included. We have a video regarding maintenance of your trailer hubs that you might find informative, I have included a link that will direct you to the video.

• Parts Needed to Install Brakes on a Tandem Trailer with Hayes 3,500 lb Axles
• You are correct, the # 84 spindle parts do interchange to 3,500 lb Hayes axles, as long as it is not a boat trailer axle, so you can use the Dexter parts on these axles. The spindle and hub parts for this application are standard parts that are still used in production, so they should be around for a long time to come. Of course keeping a record of the parts you use will help with replacement in the future. You could always return to Hayes parts in the future, the only thing to keep in mind i

• How To Remove the Brake Drum If the Brakes Are Locked On a Reinell Boat Trailer
• A trailer hub and brake drum should be able to be removed by just sliding off the spindle after the castle nut is removed. The castle nut is located underneath the grease cap. The trailer brake should not be activated. If the brake is locked that must mean that there is pressure on that wheel cylinder keeping the brake shoes against the brake drum. I would first checked the surge coupler on your trailer to see if the master cylinder is stuck or if anything is wrong with the coupler that migh

• What Size Wheel Center Pilot Hole Will Fit the Trailer Hub and Drum Assembly # 84546UC3
• I went out to the warehouse to measure the outside diameter of the center of the hub # 84546UC3. I used a set of digital dial calipers to take the measurement and came up with 2.6 inches in diameter at the widest point. The pilot hole on your trailer wheel would need to be 2,6 inches (or larger if the wheel is centered on the hub using lug nuts).

• Trailer Hub and Drum Is Stuck On Trailer and Brakes Will Not Release
• If you have electric brakes, disconnect the electrical connection from the tow vehicle. If they are hydraulic brakes make sure the trailer is not positioned so that it is pointed down a hill. If it is and it is connected to the tow vehicle, the weight of the trailer can push in actuator and apply pressure to the brakes. Once you have the hubs removed you are going to want to inspect the inside surfaces where the pads touch and where the magnet (if electric) attaches (the armature surface). I

• Does the Dexter Trailer Hub and Drum Assembly # 84546UC3 Come Fully Assembled
• The Dexter Trailer Hub and Drum Assembly, part # 84546UC3, is a trailer hub and drum with the lug nuts, bearings, bearing races, grease cap and grease seal included. It is designed to fit 3,500-lb axles. After removing your old drum and cleaning the spindle you will need to install the hub and drum with the included parts to your spindle. The hub will have the bearing races installed but the inner bearing will need to be greased and installed in the hub and drum along with the grease seal

• Grease Cap and and Double Lip Seal for Trailer Hub and Drum Assembly # 84546UC3
• For a single grease cap for hub # 84546UC3 you can use # F001518. The grease cap being slightly larger in diameter than the hub bore is normal to create a tight fit. Grease seal # 58846 is a single lip. Single lip seals do not keep grease in as well as double lip seals. For double lip you would use # RG06-050 for a pair.

• What is the Smallest Wheel that will Fit Over a 10 inch Brake Assembly
• The smallest rim that will fit over a 10 inch brake assembly is a 14 inch wheel. The smallest wheel and tire combo that is 14 inches in diameter and has the 5 on 4-1/2 inch bolt pattern would be the Karrier ST205/75R14 Radial Trailer Tire with 14 inch White Wheel # AM32153. This tire has a capacity of 1,760 lbs at 50 psi and has a speed rating of 65 mph. I attached a couple FAQ articles that you might find informative as well.

• What Parts Do I Need and What Axle Should I Install Electric Trailer Brakes On a 2009 Nissan Titan
• Electric brake systems are much easier to install than hydraulic and they require less maintenance and are more in-expensive to maintain. You will need a brake controller. The most popular brake controller we carry is the Tekonsha Prodigy. This is also my personal choice. You would use part # 90185-3050P for a Prodigy brake controller. This includes the custom fit wiring harness that will allow the brake controller to plug into the port underneath the dash for a plug and play installation.
