I bought a 2000 acura tl recently, I try to take the brake pads off because they are squicking but when I try to take the bolts from the caliper I hit a wall. I have done many brake jobs but I can't take the bolts off holding the bracket for the brakes caliper. I strip one already, I try with a pipe to give me more power but no dice. Can someone help me with somedifferent ideas I can try?
