Do all Trailer Brake Assemblies Wear Out at the Same Time

Question

Question:

I have a two axle four wheel Air Stream. Which brakes usually get more wear and wear out sooner - the brakes on the front axle or the brakes on the trailing axle? And would it be OK to replace the total brake assembly on just the two front wheels or two rear wheel, whichever wears more? Thanks for your help.

Expert Reply:

The brake assemblies of all axles should wear at the same rate assuming they are all adjusted the same. All of the wheels would be spinning at the same speed and if the brakes are all applying the same braking pressure they would all wear out at the same time.

If any of the assemblies are worn then most likely they all are worn, but if you check the condition of all of them and only a few are worn out somehow you would only need to replace the worn out assemblies.

The brake pads themselves being out of adjustment would not cause a fault code to read on your brake controller. You can check the brake pad adjustment by safely raising the trailer and spinning the tire. If you hear a slight lining drag as the tire…

The brake magnet can indeed be in direct contact with the armature surface of the brake drum, regardless of whether or not the magnet is energized. This doesn't present a problem unless the drum is worn and has grooves in the armature surface.…

Well. the reason you can't replace your old Hayes brake assemblies with the Dexter #23-105 or the etrailer #AKEBRK-6R is due to differences in the designs of the assemblies backing plates. I recommend sticking with the Hayes/AL-KO brake…

You really should have around 12 volts at the junction box and then about the same at the axles. That amount of voltage drop is most likely due to using wire for the circuit that is too light. Especially since you said you have three axles. I'd…

If you were to get bearing grease on the brake pads then they are pretty much done and would have to be replaced because you will never be able to get all of the grease off of them. It doesn't sound like grease is the problem though because the…
