Begin by removing the rear wheel before checking pad lining thickness through the caliper inspection hole until you reach a depth less than 1.0 mm (0.039 inch). Then replace the pads. Start by unscrewing the 2 mounting bolts of the
Brake Caliper followed by hanging the caliper from its position without detaching the flexible hose. Start by removing first the 2 pads along with the 4 anti-squeal shims and then take out the 4 pad support plates. The plates can be reused only if they demonstrate no deformities or cracks or have minimal wear and free from dust and rust. Before pad support plate and new pad installation verify disc thickness and runout the technician should replace anti-squeal shims while spreading disc brake grease on both sides of the inner shims but avoiding the rubbing face. You should remove some brake fluid from the reservoir before you press in the pistons by using a hammer handle or equivalent item while slightly loosening the bleeder plug when needed. Secure the caliper correctly without damaging the boot while tightening its two mounting bolts to 26 Nm (270 kgf-cm, 20 ft. lbs.). Reinstall the rear wheel by torquing it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.) and then operate the brake pedal several times before checking the fluid reaches the max line.
