Brake size and bearings for 25B21FB

Hi Everyone. I purchased a 2005 - 25B21FB Bigfoot last years. I wanting to replace the electric brakes and bearings on the RV as I do not really know how much wear is on them. I just like to be safe as they are squeaking. Can anyone tell me the correct size. I found on "e" that they recommend.

"For 3,500 lb axles, you can use the Dexter Nev-R-Adjust Electric Brake Assemblies, # 23-468 for the left hand side and # 23-469 for the right hand side."

And can anyone tell me what size of bearings to use. And what other parts I may need to do this project.

Thanks Winston

Is there nothing in your manual that tells you?

Its always best to just remove the old bearings and take them and the seals to an automotive shop and they will replace them with what you need. Assuming the bearings actually need replacing and not just a cleaning up. Just make sure you get some of the better ones such as Timken or SKF not no name brands made in china.

You may not need to replace your brake pads either - depends on how many miles the trailer has traveled with well adjusted brakes. Many trailers do not have their brakes adjusted correctly so you may find little to no wear on trailers many years old.
