Over active brake

[dutcher.ds]

We just purchased a used 2014 Coachman 23 TT. My passenger front trailer wheel brake locks up when the brake is pressed. This tire then skids/slides often burning rubber while the other three brakes seem to act normal. I have jacked up that axel and there is no noticeable friction when the wheel is spun and the brake activates when the pedal is pressed. My thought of an overly tight adjustment of the shoes may not seem to be it. When simply driving on the interstate, the drum is hotter than the other three brakes. Anyone know what is up here? Does the one over active brake need all new magnet and parts/rebuilt???

Did you check to see if the other wheels are working at all.

Just a thought

[dutcher.ds]

Good thought. Yes and they all work fine.

Assuming it stops skidding if you back off on the brake power...if not take it back to the dealer. If it does not skid When the power is reduced then it could be the other wheels are improperly(insufficient) adjusted and one brake is trying to stop the whole trailer.

Good luck with a suitable solution.

With that one tire dragging and the drum getting hotter than the others leads me to believe that the brakes need to be readjusted. You can either adjust the brakes or have some one do it for you and If it still drags after that, Then you might have internal problems. If brakes are worn out and still neglected they might be piling up on each other.
At two years old they shouldn't be worn out but some people don't know how to adjust the brake controller right and prematurely wear the brakes out. Others think their saving on their tow vehicle brakes by adjusting the controller so the trailer will take more of the braking, Also wearing the brakes out faster. No way to tell what the PO has done in the past.

You are NOT dealing with an adjustment problem or brake controller adjustment. You absolutely have to pull that drum and find the problem. Probably grease that was pumped thru the seal, or broken parts. Pull it, take photo and report back.

Two things I can think of.. one covered above (Adjustment) the other RUST,

The magnet pulls against the inside face of the drum, (not the band but the face) if that is rusty it will drag extra hard and apply hte brakes extra hard.. IF this is the case it will, eventually, self fix if you have progressive/porportional brakes.. but would be better to fix it faster.

X2 for sure!

ok. did you buy from a dealer? if so take it back and have them fix it. if you bought from a private concern then take it to a local dealer and have the brakes fixed. get it to a professional....

just my humble opinion.

I had the same problem on mine. It only did this when I had the brake controller set to "heavy electric". On "light electric" it works normally. It did this the same before and after adjustment and had nothing to do with heat.

I know this makes no sense and all four should work equally.

Make sure to rule out obvious stuff like low tire pressure, too.

Could it be the first magnet in the circuit. Hopefully they would even out the wire runs.

I agree with lynnmor, I would either pull the drum or have a qualified tech pull the drum and find what is wrong, my guess is that either the brakes are out of adjustment, or there is grease or broken hardware on that brake., no way to know what is going on without pulling drum for proper inspection.

That's what I thought too.
