Just complete a brake job on my ridge consisting of using WAGNER BD126355 Premium rotors for the front and WAGNER BD12635 Premium on the back, WAGNER PD1103 ThermoQuiet pads on the rear and WAGNER PD1102 ThermoQuiet pads on the front. Also, RAYBESTOS Professional Grade caliber pin guides where used all the way around. Flushed all the oil brake fluid out and filled with new. The problem is I a can hear a grinding noise from one or more of the rotors as I get close to coming to a complete stop. What do you think the problem is? The calibers are all original OEM with 209K on them. However, nothing was grinding before this brake job with about 3mm left on the old brake pads. Is or more calibers hanging up? Thanks for your input and help.
