Default Squeaky noise.

ok so i recently installed a new set of rotors/ pads on the Bonneville, and they work great. I mean its the sexiest stopping i've ever experienced.lol Anyways now im noticing that when i turn right i hear this high pitched squeaky noise, but only when i turn right. and sometimes after i turn right the squeaky sound will continue just as the wheels are turning and no braking is being done. im thinking its either a wheel bearing gone bad, which i have thrown no codes for, or possibly a dry ball joint. What do you guys think?

Did the pads have backing plates on them? If not.. you might need to use some disc brake quiet stuff to glue them in and stop the squeaking

Glue the pads in? they had some kind of material on the back of them, but I wouldnt describe it as a plate. and I did apply that grease to the back side of them. I wouldnt have guessed it to be the pads tho. Right after the install, everything worked great, i had gotten rid of that pesty shudder that i originally had when i'd brake. but then on may way home from the garage (about 15 min later) all of a sudden this squealing starts. And at first it was a constant noise, i wouldnt have my foot on the brake or anything. so i drove to an empty lot did a few forward hard stops and a few reverse hard stops, and then it got quiet accept for when i turn right. and even now sometime it will go in out from only squealing on right turns to a constant squealing while the wheels are in motion. Its VERY annoying and a little embarassing, especially for my bonnie.LOLOL

Drive about 35 MPH and apply solid pressure to the brakes to slow to about 5 MPH then back to 35 and do this like 5 times but do it so you won't have to keep the brakes applied without the car moving, make sure the rotors have time to cool before you hold them on for a long time

basically you heat up the pads and rotors to break them in and get the proper amount of pad material on the rotor

I've seen different speeds and times like from 80 to 35 or 10 times, 3 times, etc...

if the pads sit on a hot rotor that isn't moving you leave more pad in one part of the pad and it might cause squeeking, also don't put yourself through the windshield until you break them in good or they will wear out prematurely
