BMW X5 Brake Noise. HELP
I recently acquired a 2001 X5 and the rotors were so terrible that when braking the car felt like you were riding a paint agitator. It was ridiculously violent. The day I got the car, I replaced the front rotors and reinstalled the existing pads with the brand new rotors. I didn't apply lube to the pads(not sure about doing this really) but I did lube the slide pins. The rotors are Wearever rotors from Advance auto parts. After installing the new rotors, all seemed well. However it began making this squeaking noise while driving and NOT under braking. It is a very rhythmic sound, it's tempo increases directly proportional to the wheel speed. Also there is a slight grinding when braking lightly. It sounds like the pads are made of some very abrasive material such as concrete. Also a slight popping/craking sound happens sometimes when braking like a bushing or something is bad. The grinding stops under heavy braking as well as no braking. The sqwuaking squeaky sound is dormant for about sixty seconds after the pads and rotors have cooled all night. Before I even get to the main road(takes slightly more than 1 minute) the sound has begun for the day and will not cease again until the next morning(again for only one minute). Other issues with the car include the "trifecta" or whatever will the instrument cluster looking like a christmas tree. My ABS, BRAKE(yellow), Traction control, (some light I'm not sure the name of but has to do with ABS braking speedo stuff). Speedo doesn't work. I have since replaced the new rotor with another new rotor and nothing changed... This is on the front passenger side. Please help me. I'm thinking it could be a bad caliper maybe?
