First remove the front wheel and check the pad lining thickness through the caliper inspection hole before pad replacement when the lining thickness falls below 1.0 mm (0.039 inch). Holding the sliding pin in place enable you to lift the caliper and remove its bottom installation bolt while keeping the flexible hose intact with the brake caliper before securely suspending the caliper. The maintainer should begin by removing the pads along with their corresponding anti-squeal shims and pad wear indicator plates before proceeding with the two pad support plates. These plates can be reused when free of deformation, cracks, and wear and Rust and Dirt are absent. Disk measurement results lead to placing two support pad holders correctly. Install these plates only when disc runout values pass inspection. Replace all pads with new ones as well as their corresponding anti-squeal shims and wear indicator plates during installation; users of the 2ZZ-GE engine must put a pad wear indicator on each pad and must spread grease on both sides of each inner anti-squeal shim and users of the 1ZZ-FE engine need to distribute the grease on the outside edge of the inner anti-squeal shim. After installing the two anti-squeal shims on each pad apply them in a position where the pad wear indicator plate points upward while ensuring the friction surfaces remain free of oil or grease residue. A small amount of fluid should be drawn from the reservoir before pressing the piston inward using a hammer handle or equivalent tool; when piston resistance is high loosen the bleeder plug to vent fluid while pushing in the piston. Position the caliper after keeping the sliding pin intact during installation before tightening bolts to 34 Nm (350 kgf-cm, 25 ft. lbs.). Install the front wheel before torquing it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.). Then depress the brake pedal several times to check the fluid level reaches the max line.
