Honda 8-94361-927-1 Rotor, Front Disk Brake

Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands before removing the wheel. Remove the brake caliper without disconnecting the brake hose, and suspend it out of the way with a piece of wire, ensuring it does not hang by the hose or stretch it. Visually inspect the disc surface for score marks and damage; while light scratches and shallow grooves are normal, deep score marks over 0.015-inch (0.38 mm) necessitate disc removal and refinishing. Check both sides of the disc, and if pulsating occurs during braking, suspect excessive disc runout. To check runout, position a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc, ensuring the reading does not exceed the allowable limit; if it does, the disc should be refinished. It is advisable to resurface brake discs to eliminate brake pedal pulsations, and if not resurfaced, deglaze the brake pad surface with emery cloth or sandpaper using a swirling motion. The disc must not be machined below the specified minimum refinish thickness, which can be checked with a micrometer. Remove the two caliper support bracket bolts and lift off the bracket. For front disc brakes, remove the front hub/disc assembly, then unbolt the disc from the hub. For rear disc brakes, remove the disc, and if it is stuck, use a bolt in the threaded hole to break it loose. Install the front disc onto the hub and tighten the bolts in a criss-cross pattern to the specified torque. For the rear disc, slide it over the wheel studs onto the axleshaft flange and secure it with a retaining screw. Reinstall the front disc and hub assembly, adjusting the wheel bearing as necessary. Install the caliper support bracket and tighten the bolts to the specified torque, then install the pads and caliper, tightening the caliper pins. Finally, install the wheel, lower the vehicle, and depress the brake pedal a few times to bring the brake pads into contact with the disc, checking the operation of the brakes before returning the vehicle to normal service.
