Pad Kit, Disc Brake, Front

Inspection of pad lining thickness through the caliper inspection hole is necessary before pad replacement. Pads require replacement when the lining measures less than 1.0 mm (0.039 inch). The brake caliper needs lifting by removing the bracket bolt and its attached flexible hose followed by removing the bottom installation bolt while securing the caliper without disconnecting the hose. Start by removing both brake pads together with their four anti-squeal shims next remove the pad wear indicator plate with the four shims then take the two pad support plates that may remain usable as long as they are free of deformation cracks wear and clean of rust and dirt. Without disc runout inspection verify that two pad support plates are suitable for installation. To replace the pads, both anti-squeal shims and wear indicator plates should be replaced simultaneously by first installing the pad wear indicator plate on the inner pad followed by brake grease application on both sides of the inner anti-squeal shims before adding the two anti-squeal shims to each pad. Insert the inner pad first while orienting its pad wear indicator plate in an upward position followed by the outer pad but maintain oils and greases off friction surfaces. To install the caliper you must first draw out a little brake fluid from the reservoir before using a hammer handle or similar tool to press the piston while loosening the bleeder plug if necessary (install the caliper last with an installation bolt torque set to 34 Nm or 350 kgf-cm or 25 ft.lbs.). Insert the front wheel onto its hub and torque it to 103 Nm (1,050 kgf-cm, 76 ft. lbs.), but before doing so which torque the flexible hose and bracket with 29 Nm (300 kgf-cm, 21 ft. lbs.). Use the brake pedal to create several depression strokes before examining that fluid reaches the max mark.

First, remove the rear wheel and temporarily fasten the disc with the hub nuts.

Install 2 or 4 pad support plates followed by new pads, ensuring that the anti-squeal shims and wear indicator plates are replaced with the pads.

Hold the sliding pin while torquing the installation bolt to 34 Nm (350 kgf-cm, 25 ft. lbs.) and reinstall the flexible hose and bolt to the shock absorber bracket, torquing to 29 Nm (300 kgf-cm, 21 ft. lbs.).

Check the disc thickness and runout.

Install the inner pad with the wear indicator plate facing upward, followed by the outer pad, ensuring no oil or grease is on the friction surfaces.

Check the disc thickness and runout before installing the four pad support plates.

Lift the caliper by removing the bottom side installation bolt and suspending it securely without disconnecting the flexible hose.

Lift the caliper by removing the bolt and flexible hose from the shock absorber bracket, followed by the bottom side installation bolt, and suspend the caliper securely without disconnecting the flexible hose.

Check the disc thickness and runout before installing the four pad support plates.

Attach the flexible hose and bolt to the bracket, torquing to 29 Nm (300 kgf-cm, 21 ft. lbs.).
