Grinding noise from new rear disc brakes 2002 Pontiac Grand Prix?

Question

I recently replaced my rear brakes, even though it wasn't absolutely necessary, and changed my rear struts. If I apply the brakes at highway speed there is a loud grinding noise and you can feel it too. What is wrong? The car has 85,000 miles and I did not see any rotor damage when I replace the brakes.

Answer 1

You never change pads without changing rotors! Throw a new set or rotors on the car and you'll be good to go.

Answer 2

I only concept i necessary to reiterate, it quite isn't a humorous tale in any respect. do no longer force the automobile. I had a save fail to swap a cotter pin and that i had a wheel fall off on the line. Your autos suspension is truly important, if it fails at severe speeds you would be in an truly severe twist of destiny. This concern would be a pair of issues. i might say jack up the completed front end of the automobile and wiggle the wheels forward and returned along with your left hand at 9 o'clock and your good at 3 o'clock. you ought to have 0 circulate. If the wheel strikes then you quite're maximum in all probability finding at a bad inner tierod bushing, a ability steerage rack or per hazard even a tierod end. (i think of on a '02 GA you have gotten the tierod end bolt down into the rear-maximum arm (for loss of an greater term) on the strut. The tierod end (AKA "Outer Tierod") is hooked as much as the internal, this is then related to a extensive tube this is your ability steerage rack.)
