Hey i have a 2000 sunfire 4 door and i have a Klunksh noise in my rear brakes. when i hit the brakes it goes klunksh and it feels like they are sticking together, then they release. this only really happens when i take out the car for the first time of the day. i have ABS, but when this happens the ABS doesnt work and my tires just lock when i hit the brakes and the right rear suspension goes right down??? thx
