I'm just nuts over this product. Seriously though thanks fro getting the items to me in a timely manner. I am on Evacuation Advisory for the huge Rim fire that is currently happening in California. I live just a few mile from the perimeter of the blaze. The fifth wheel is all loaded up and ready to go but I was having troubles with the electronic brakes. Now I should have tome to get these new ones in place if and before the word to evacuate comes through! Thanks again!

Replacing the brakes on a 50 year old FAN camper. After being assured that it had 10 inch brakes by another company"s "expert" because it has a 3500# axle, I finally received the correct 12 inch brakes from eTrailer. They arrived very quickly, and packaged well. The installation went almost as easy as the very helpful online video showed. Only difference was I had to slightly tighten the brakes to slide the hub over them, even though they are self-adjusting once in service. I have never owned or worked on a trailer before, and the installation was relatively easy. Thank you to George J for the followup email within 24 hours of delivery.

Nuts and bolts are nuts and bolts but I can report that the self-adjusting brakes have worked well on our two-thousand mile trip this summer through the mountains of Utah, Idaho, Nevada, Oregon and Washington. They stop straight and true and don't seem to fade on those long down grades like the infamous "Cabbage Hill" near Pendelton Or.

US made product, great service from Erika who sorted out my information as to what type of brakes I needed, and fair price. I was very pleased with the follow up emails and the pro service that was provided. Never used Etrailer before, but will be a return customer. Thanks

bought a brake assembly that needed fastening to the axle; these nuts, bolts and washers were just what I needed. Thanks George J.

The whole order was perfect. I'm rebuilding the running gear on a1976 3 horse slant then remodeling the whole trailer by converting the trailer into a communications trailer for HF radio for disaster response. Front area will be living quarters. I am in our State Guard as a radio operator and also in county emergency management. This trailer will be my shelter and operating station when deployed to hurricanes and such. Since I'm spending my own funds on this, the good prices on etrailer are greatly appreciated.

Carla M. worked with me to make sure we had all the right parts for my boat trailer. I am quite happy with her help.

My package arrived on time just as I expected. I was a bit disappointed with the packing. Everything came in one box. The nuts were not in any bag they were just loose in the box. I ordered 10 but I only received 7. I think the other 3 fell out the bottom of the box that was not completely sealed with tape. You might want to put small parts in a zip lock bag. I ended up replacing new bolts one one side instead of both.

Ordered lots of parts on Monday, received most of them by Thursday. The received parts were well packaged and undamaged. A few of the parts they didn't have in stock so they had those drop-shipped to me which should be delivered in the next couple of days.
No supplier I have ordered any parts from has such a great technical reference web site or personal customer support. Yea, Rebecca - Well Done! Yes, I'm very happy with the pricing.
Thanks for your great support and I look forward to doing business with them again. More info to follow as soon as I can get the parts installed on my trailer.

- Recommended Electric Brakes For Timbren Axle-Less System And Dexter Trailer Hub/DrumThe electric brakes I recommend to use with the Trailer Hub/Drum, part # 8-219-50 and the Timbren Heavy-Duty Axle-Less Trailer Suspension, part # ASR35HDS02 is the Dexter 12 inch Nev-R-Adjust Electric Brake Assembly, part # 23-459 for the right hand side. For the left hand I recommend part # 23-458. The mounting hardware for the brake systems is not included. You will need part # 38LW, part # 38N, and part # 7-5. For each brake you will need 5 of each.
view full answer... - Nut to Match Wheel Stud # 007-112-00I believe you are looking for the correct nut to fit the stud part # 007-112-00 which would be the # 38N.
view full answer... - Replacement Bushings and Brake Assemblies for 6,000 lb Axles with 4-Bolt Brake FlangeFor your brake assemblies with the 4-bolt mounting flange, you will want the Dexter Electric Brake Kit for 4 Bolt or 5 Bolt Flange- 6K # 23-105-106-09. You will need one set for each of your 3 axles. If you need the mounting hardware the Brake Mounting Bolt for 12" Brake Assembly # 7-5 and lockwasher # 38LW along with nut # 38N are what you will need. For your bushings you will want the Two Piece Nylon Bushing - Qty 4 # SP05-080.
view full answer... - Replacement Hydraulic Brake Assemblies and Drums with 008-201-09 Casting Number for Boat Trailer The 008-201-09 number you provided comes back on a Dexter Axle hub that we offer as part # 8-201-9UC3-EZ, a 12 x 2 inch brake drum. This hub uses a 25580 inner and 15123 outer bearing, so please check the reference numbers on your existing bearings to confirm that this hub is compatible. These hubs use a grease seal with a 2-1/8 inch inner diameter. Since it's kind of difficult to measure the inner diameter of a used grease seal, measure the OD of the spindle where the grease seal rides....
view full answer... - Recommended Brake Assemblies For Dexter Axle 3500 lb And 5200 lbI reached out the the manufacturer and found that they have two possible axles that meet that criteria. One is definitely more likely your application than the other, but I will give you both brake assembly options. For a 3500 lb axle, you will want the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA. This will give you both the left and right assemblies. There is a sticker to help you with which assembly fits which side....

view full answer... - What Kind of Steel is Brake Mounting Bolt 7-5 Made FromThis Brake Mounting Bolt for 12 inch Brakes Assembly, part # 7-5, is not made of stainless steel, it is made of regular steel. You might also be interested in purchasing a Nut for Brake Mounting Bolt for 12 inch Brake Assembly, part # 38N, and a Lockwasher for Brake Mounting Bolt for 12 inch Brake Assembly, part # 38LW.
view full answer... - Brake Flange Nut Recommendation for Securing Brakes to Timbren Axle Less 3,500 lb KitThe size of nut required to secure a brake assembly to the mounting flange of the Timbren Axle Less kit part # ASR35HDS02 is a 3/8 inch, fine thread bolt like # 38N.
view full answer... - Pilot Hole Dimensions of 12 Inch Electric Brake Assemblies And Recommendation With 4 Bolt MountingI went out to our warehouse to measure for you and both the # AKEBRK-7-SA and the # 23-106-09 assemblies have a pilot hole dimension of 3.23 inches. Because you mentioned you have a 4 bolt assembly, that narrows down your axle to an AL-KO axle and you will definitely want the brake assembly # 23-106-09 and # 23-105-09. The other assemblies won't accommodate your 4 bolt mounting pattern. You may also want the mounting bolt # 7-5, lockwasher # 38LW, and nut # 38N. If you don't have an...
view full answer... - Will Dexter Brake Assemblies Fit on a Lippert AxleYou will have no problem using a Dexter brake assembly on a Lippert 7K axle. We have installed several Dexter brake assemblies on Lippert axles at our shop. Lippert and Dexter use the same standard mounting pattern and brake sizes. If you want standard brake assemblies, you could go with the Right Hand brake # 23-181 and the Left Hand brake # 23-180. I recommend stepping up to the Dexter Nev-R-Adjust brakes, # 23-465 and # 23-464. The cost difference is very minimal compared to the standard...
view full answer... - Brakes for 12" x 2" Drums and 4-bolt Mounting PatternWe only have one electric brake assembly that may work for you, the Dexter Electric Brake Kit # 23-105-106-09. This kit fits standard 5-bolt mounting flanges or AL-KO/Hayes 4-bolt flanges. If you have that type of 4-bolt flange you would likely know it because the pattern is offset, with the upper mounting bolt holes spaced further apart than the lower holes. These brakes are rated for 6,000 lbs and would require Brake Mounting Bolts # 7-5, Nut # 38N and Lock Washer for Brake Mounting...

- Width of Brake Pads on 28 Foot Gooseneck Trailer With Dexter 10K AxlesTo determine which brake assembly you need, measure the width of your brake linings, as shown in the photo I edited for you. If your existing brake shoes measure 4 inches wide, the # 23-438 you mentioned would be an example of a good replacement for you if your existing brake assemblies use 7 mounting bolts (some use 4) and the diameter of the assembly is 12-1/4 inches in diameter when measured from the outside of one brake shoe directly across to the outside of the other shoe as shown...

- Replacement Dexter 6K Electric Trailer Drum BrakesTo replace your Dexter right-hand 6K electric drum brake 023-358-00 you can use part # 23-106-09. For a left-hand brake use part # 23-105-09. If you decide to replace both left and right brakes we offer both in a set as part # 23-105-106-09. These brakes fit both 4-bolt and 5-bolt brake mounting flanges. If you need mounting hardware you can use bolt # 7-5, lock washer # 38LW and nut # 38N.
view full answer... - Replacement Self Adjusting Brake Assemblies for Lippert 7k AxlesSelf adjusting brake assemblies have no downside. They are the preferred brake assembly style as they require no adjustments. The part # AKEBRK-7L-SA is the correct left hand side assembly for your trailer with 7k Lippert axles. For the right hand side you'd then want the part # AKEBRK-7R-SA. For grease seals you then would want the part # RG06-070. For bolts you'd need the part # 38N and for a washer part # 38LW.
view full answer... - Recommended Brake Assemblies and Hubs with Oil Bath For Dexter 8,000 lb AxlesFor your 8,000 lb axle hubs with oil bath, I recommend the Trailer Hub and Drum Assembly - 8,000-lb Axles - 8 on 6-1/2 - Oil Bath, # 8-285-10UC3-A. The brake assemblies I recommend to match the hubs are the Electric Trailer Brake with Dust Shield - Self-Adjusting - 12-1/4" - Left Hand - 8,000 lbs # AKEBRK-8L and # AKEBRK-8R for the right hand side. You may want the Brake Adjustment Spoon for Drum Brakes # W80630 for the initial adjustment, but these brakes with self-adjust after that. If...
view full answer... - Selecting Correct Replacement 12 x 2 Electric Brake and Drum Assembly for 6000-lb AxleThe best way to identify the correct replacement components for your trailer is by using the part numbers from your current inner and outer bearings and grease seals (or a spindle measurement where the seal and bearings ride). It is possible to measure the spindles to obtain grease seal dimensions (location B on the photo) but this process requires care and a precision digital caliper like # PTW80157. You will also need to confirm the diameter of your wheel studs. We already know your brakes...

- USA-Made Dexter 12 x 2-Inch Electric Drum Brakes for 2003 Mobile Suites Trailer with Tandem 7K AxlesFor Made in America 12 x 2-inch electric drum brakes for your 2003 Mobile Suites trailer with tandem 7K axles I recommend the Dexter kit # 23-464-465 for each axle if you want self-adjusting brakes. If you prefer standard manual-adjust brakes instead then use two of kit # 23-180-181. Either way you will want to order two kits to be able to fit new brakes on both axles. For mounting hardware you can use parts # 38LW, # 7-5 and # 38N (five of each per brake) and for a brake adjustment tool...
view full answer... - Are New Backing Plate Bolts Included With Electric Brake Assembly for 6K Axles # 23-459I walked out to the warehouse to look at the Electric Brake Assembly for 6K Axles, part # 23-459. The brake assembly does not include the backing plate bolts. I would recommend installing new bolts and nuts for easier installation and safety. For mounting bolt, you would need Brake Mounting Bolt, part # 7-5, which is sold as a quantity of 1. For mounting nuts, you would need Nut for Brake Mounting Bolt, part # 38N, which is also sold in quantity of 1. You will also want to use Lockwasher...
view full answer... - Brake Flange Mounting Bolt Recommendation for Kodiak Disk Brake Kit K2R526DThe brake flange mounting bolts are not included with the Kodiak Disc Brake Kit # K2R526D that you referenced. If you need bolts you would want the part # 7-5 for the bolt, part # 38LW for the washer and part # 38N for the nut. These aren't stainless, but they will still work fine. If you wanted to go with stainless you would have to source them at a hardware store.
view full answer... - Can the etrailer.com Brake Assemblies Replace Hayes AL KO Brakes AssembliesWe have brake assemblies that will work for you, but unfortunately it will not work to replace your existing Hayes/AL-KO brake assemblies with our self-adjusting brake assemblies. For your Hayes axle, you will want to use the 12 Inch Electric Brake Assembly, Left Hand # 23-105-09 and Right Hand # 23-106-09. These brake assemblies are designed to work as replacement assemblies for Hayes/AL-KO axles so they will work well on your trailer. The reason other assemblies will not work for your...
view full answer... - Does Dexter 12 Inch Electric Trailer Brake Assembly # 23-181 Include the Mounting HardwareThe replacement right-hand brake assembly you referenced, part # 23-181 does not include the mounting hardware. You'll need 5 of the # 38N nuts and 5 of the # 7-5 bolts. Something else to be aware of, some time ago Dexter stopped including the mud and crud plugs that cover the brake adjuster holes. We offer them as part # BP10-220 for 4 plugs.
view full answer... - Will Electric Brakes Bolt On 7,000 Pound Torflex Trailer AxlesThe Electric Trailer Brake Assembly, Self-Adjusting # AKEBRK-7L-SA that you referenced will bolt directly to the 5-bolt brake mounting flange on your 7,000 pound trailer axle. The # AKEBRK-7L-SA is the brake assembly for the left hand side of the trailer. The brake assembly for the right hand side is # AKEBRK-7R-SA. These brake assemblies fit hubs that measure 12 inches diameter x 2 inches thick and will work well on your 7K torflex axle. I've attached a review video of this brake assembly...
view full answer... - Replacement Brake Assembly Set for 2004 Sunnybrook Solanda 2726Hey Mike, thanks for all of the info you got me. Based on that the correct brake assembly set for your 2004 Sunnybrook Solanda 2762 is the part # 23-105-106. This comes with new mounting nuts. You should have no problem using the studs on your mounting flange again.
view full answer... - Drum Brakes with Parking Brake for Timbren Heavy-Duty Axle-Less Trailer Suspension ASR35HDS02With the Timbren axle-less suspension system # ASR35HDS02 you can install 5-bolt electric drum brake assemblies like # 23-112 and # 23-113. These are left- and right-hand brakes with parking brake mechanisms that are rated for a 6K axle system. You can use lock washer # 38LW and nut # 38N to install the brakes. If you need a brake adjustment tool we offer part # W80630.
