Anybody have an issue like this before? Trailer is empty and when I apply the brakes for normal stopping pressure such as stop light, slow manuever stops in parking lot etc. the front axle trailer brakes lock up and the trailer bounces. I didn't have any issues until I was empty. Trailer has been in the shop since Sunday. The T/A shop mechanics couldn't find anything. They say all is as should be can't find problem. Brought trailer to trailer shop 5 miles down the road and they can't see why it's behaving the way it is either.

It could be an issue with the ABS or drain the air tank under the trailer.. it might have crud in it or there's a blockage in an air line. Or slack adjusters on 1 or 2 wheels that's seized (or slack adjusters are bad, even if you have automatic slack adjusters)

It's the 4th axle only, right? Those things could cause that problem.

If all is as it should, means, no obvious damage, broken parts, etc... It's got to be an adjustment problem

They say all are adjusted as shoild be. The front axle has new drums and pads. They're gonna put new ones on rear axle and see if this helps. Beginning to think I need to make a change of address to CA. Man am I getting itchy feet. I've read six books this week.
