Well was 60 miles from home. parked the car to do some business ! Got back in car, put in reverse.....no movement, fowards very little movement. Finally said F it put in reverse and mashed the gas, heard a noise after it broke free, went to inspect, and found my inner brake pad..... the slider pin on the caliper bracket was frozen causing my pad/rotor contact. Limped the car home. thought ineeded a brake caliper so i got one. wrong one, the next 2 were wrong also.. The mouting bracket that came with all three calipers were to short in height. But i found a brake caliper slider pin at my local parts store..................... Yep....i'm a dumazz for not inspecting further. Put the new Wagner Thermo Quiet Ceramic pads and new rotors,,,,,,,, love those pads they are great !!!!! So there was the answer to my brake problem= a frozen slider pin.
