This started happening 3 days ago. When i start my 94 Camaro and begin to drive after it has been sitting for a few hours,the brakes lock up when i lightly touch the brake peddle. It feels like the rear passenger side is locking up, it locks so hard it causes my low track to kick on. They lock up when i stop with just the Emergency brake also, after a few minutes of driving and stopping the brakes seem to go back to normal.... Any ideas of what it might be?
I haven't done any work on it recently, but i did just have it inspected a week ago, it passed fine.

try to see if you have a pinched line some where in your brake sys this would cause the some problem not letting the pressure out of the cyclinders. also i would have all the rubber brake lines checked i have seen some lines that actually wearing from the inside. and in this case the rubber ended up acting like a check valve you could apply brakes but when you let off the fluid would come back through the line and the flap would be pushed back and would lock the brakes. also check your brake fluid any kind of dingy looking oil needs to be drained.

Also check the axle seal back there. Might be oil on the brake shoes.

check the adjustment on the shoes. if the axle seals and wheel cyls are dry, and the adjustment is ok, i would probably replace the shoes

hey dude, the wheel cylender's could be hanging up also, and the return spring could be going, you need to do a brake job ASAP on the rear, we are talking bout safty here. there are so many thing's that could cause this. if it was my car i would do a complete brake job, drum's, hard ware, cylendrs the whole thing! a out of round drum can cause this too. good luck i know i am a doom sayer here but i used to be a ASE cert. brake tech and i have seen a few bad thing's happen from not doing it right. oh ya and the proptioning valve might be sticking too i have seen this too. good luck!

I think that you have out-of-round brake drums.
