I've had that problem.
ALWAYS went away when truck gets new drums and shoes.
THere's 10 brakes. They don't function too kindly when half are new drums and the other half are warped drums. The warped drums require a lot more pressure to stop then new drums which don't require much pressure.
The trailer is locking up. While the truck is trying to stop.KWP_15 Thanks this. -
what do you have for a tractor? are both tractor and trailer drum? Have you tried Swapping Truck/trailer to duplicate it? Did you adjust the brakes and grease the scam/slacks?
KWP_15 Thanks this. -

I would try a different trailer if you could, we had one truck the truck/tractor protection valve went and would basically lock the brakes any time you hit the brake pedal, or something to atleast confirm truck side or trailer side
KWP_15 Thanks this. -
I have the same problem recently. Hoping you get this figured out for both our sake! I was told it’s the control valve but sounds like you already changed that.
For my problem it’s not the tractor brakes either. Doesn’t matter which truck pulls it.KWP_15 Thanks this.
