Initial Adjustment Of Nev-R-Adjust Electric Brakes  

Some hub/drum assemblies can accept either electric or hydraulic brakes and some can only accept one or the other. It has to do with the amount of space inside the drum itself. The Trailer Hub and Drum Assembly, #8-257-5UC3, is designed for…

Some drums can be used with hydraulic or electric brakes and others cannot. You would have to check with the drum manufacturer unless it specifically says on the drum somewhere. You mentioned a ridge which would indicate to me that you may not be…

If the surface on the inside of the drum where the shoe pads make contact isn't smooth then a brake shop may be able to turn the drums. If that surface or the surface where the magnet makes contact (called the armature surface) is discolored then…

That number is probably 4 mm which that amount is acceptable. Normally trailer brake thicknesses are done by inch though. 3/16 of an inch is what they are new and then they should get replaced at 1/16 of an inch.

To service your Dexter electric trailer brakes #23-458-459 you can use Nev-R-Adjust 12 x 2 brake shoe/lining kit #K71-676 (right hand) and #K71-675 (left hand). I confirmed their fit with the tech team at Dexter. You will probably find that the…

I went out into our warehouse to measure the pad thickness of a Dexter 3,500 10 by 2-1/4 inch brake assembly like the part #23-468-469 and just the brake pad portion of the shoe measured .18 of an inch. The entire shoe thickness was .29 of an inch…

The three sizes of electric trailer drum brakes you referenced, 7-, 10- and 12-inch diameters, are intended for different axle weight capacities. Since each size will presumably have a proportionate weight load it has to stop, their wear rates will…

The brake pads on the 12" Dexter Electric Drum Brake Kit #23-180-181 are 3/16" thick. Dexter Axle recommends replacing them once they get down to 1/16" thick.

For your 5,200 lb Lippert axles I would recommend the Dexter brake assembly part #23-459 for the right hand side of your trailer and part #23-458 for the left hand side. Both these assemblies are 12 by 2 inch assemblies designed to fit the 5 bolt…

On Dexter 12" Nev-R-Adjust Electric Brake Assembly #23-458 the shoe pad thickness is 3/16 of an inch. Dexter says that you should replace the shoes if the material gets down to 1/16 of an inch thick or less.

For your 5,000lb axle, with a 12" brake assembly, you can use the: -Dexter Nev-R-Adjust Electric Trailer Brake Assembly #23-458. Even thought this is stated to work for a 6K axle, it will work perfectly fine with your 5K axle. Should you want…

The 2-1/4 and 2-1/8 grease seals are usually interchangeable but manufacturers have started going to the 2-1/8 model for a tighter fit. So what you would need is #GS-2125DL for one seal or #RG06-090 for a pair. We can't swap the seals out of a…
