BAD BRAKE CALIPERS OKAY YOU ALREADY MADE A THREAD ABOUT THIS BEFORE.

 

thats not the problem either. I'm new to these forums that's why I started a new post instead of the reply.

 

alrighty, try your pistons within the calipers, did you do that?there isnt much else to it

 

it should"t be the calipers ,once they go bad they stay bad and it is not very likely to have two bad calipers at the same time. actually it almost never happens at th same time. If it is only when you turn the car on i would say you power brake booster is causeing the brakes to engage and stick. another thought would be the antilock brake system. may need to be bled, that could cause the brakes to lock when the car is turned on, or keep them locked even when power was shut off. have you done anything to the brakes since it started happening??
