i have a 2002 cavalier. i felt a vibration in the break pedal and my brake lights came on. i found out i needed brakes. so i have brand new brakes all around the car. well the problem hasn't stopped.

How did the old brake pads look when they were removed ? Was the inner brake pad worn down more then the outer or vise versa on either the left or right side caliper ? Was the caliper piston hard to push back in on either the right or left caliper ?

Did you also install new rotors ?

the driver side rear was completly worn. but the front driver and front and rear passenger werent all that bad. my emergency brake also didnt work. and still doesnt work. and the caliper piston wasnt all that hard to push in. and the rotors werent bad.

The rotors may look good but if the vehicle was vibrating when brakes are applied rotors are warped they need to be resurfaced or replaced m.

i never thought about them being warped. totally slipped my mind.

Agree with firechicken on this. Calipers warped loose lug nuts. Try rotors and hold your mouth right this time. Vital part to it is holding your mouth right
