Thought I fixed it buy putting on a new rotor but I guess not. I have yet to take it appart (because I am sick of doing it) but it sounds like some thing is loose or got loose since I put on the new rotor. also it only does it once a rotation of the wheel and and when I pull the E-brake up about half way (4-5 clicks) or when I barly push the pedal.
But when I put the new rotor on it didn't make noise. I got the brakes hot on purpose and also drove it normal no noise for 2 days and started back very softly now it's just as loud as before. someone if you can help please do. thankx
