Rotor, Front

When servicing or repairing the front brake rotor/disc start by taking off the front wheel followed by a temporary fastening of the disc hub nuts to a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.). The flexible hose becomes detachable by first unfastening its union bolt and accompanying gasket from the caliper and then following with hose separation while tightening to 30 Nm (310 kgf-cm, 22 ft. lbs.). A protective flexible hose lock needs installation into the caliper lock hole when reinstalling while keeping a suitable container to collect any released brake fluid. Remove the caliper by holding the sliding pin while loosening each of the two installation bolts to a torque of 34 Nm (350 kgf-cm, 25 ft. lbs.) before removing it from the torque plate. Sever the pad contacts from their anti-squeal shims before taking out both pad support plates. The installation process starts with performing reverse removal steps but requires brake fluid addition to the reservoir followed by a brake system bleed then leak checks must be conducted afterward.

Remove 2 pads along with 4 anti-squeal shims and finally, the 4 pad support plates.
