1998 camaro, disk brakes all around. my car is only stopping with the front brakes only. i was told it was a valve or something. i lifted the back wheels and i put it on drive and i pressed the brakes hard and the back wheels didnt stop at all. and when i drive and stop the front sinks too much.

help would be apreciated.

 

I would try bleeding the bakes first before replacing anything. Also check your pads when you have the wheels off.

 

check your back calipers, and if the pistons are moving in a out. also make sure the master cylinder is pumping to the back brakes. let us know from there

 

i will try that as soon as the weather clears up. i will keep u guys posted.

but thanks for the help.
