I bought new front brake rotors from autozone. I installed them and the calpiers rub on the new rotors so much that it causes a major drag, so bad the truck isnt drivable. So I took the wheel off to see what was going on and the caliper dosent "retract" or "reset" back far enough to clear the rotors. When I was installing the rotors I used a c-clamp to compress the pistons so I could install them in the new rotors, they had plenty of clearace when I compressed them. But when I put the calpiers back on and pump the brake a few times they clamp down on the rotors and then retract just a little. Once I press the brake pedal the front wheels almost lock up to where I can free them by hand. I put the old rotor back on the passenger side and the calper self adjusts properly, it works fine with the old rotor. So are my new rotors too big, are they too thick? I noticed on of the rotors wasnt completley round I could spin ot with the calpier removed and clearly see a "whobble" it is obviously out of round.
I bought the rotors from auto zone and they said NEW the rotors should be 31.6mm thick.
I measured mine with a digital calpier and it measured 31.86mm
It is just slightly larger, should .2mm make that much of a diffrence? I am using my old brake pads and calipers so they are worn, I would thing the slightly worn pads would make up for the .2mm diffrence?
Thoughts, questions, comments?
