FRONT DISC BRAKE

BR-21 Component:





WARNING: Clean dust on caliper and brake pad with a vacuum dust collector to minimize the hazard of air borne particles or other materials.

CAUTION:
^ While removing cylinder body, do not depress brake pedal because piston will pop out.
^ It is not necessary to remove bolts on torque member and brake hose except for disassembly or replacement of caliper assembly. In this case, hang cylinder body with a wire so as not to stretch brake hose.
^ Do not damage piston boot.
^ If any shim is subject to serious corrosion, replace it with a new one.
^ Always replace shim and shim cover as a set when replacing brake pads.
^ Keep rotor free from brake fluid.
^ Burnish the brake pads and disc rotor mutually contacting surfaces, after refinishing or replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage.


Removal and Installation of Brake Pad

REMOVAL





1. Remove tires from vehicle with power tool.
2. Remove lower sliding pin bolt.
3. Hang cylinder body with a wire, and remove pads, pad retainers, shims, and shim covers from torque member.

CAUTION: When removing the pad retainer from the torque member, lift it in the direction indicated by the arrow in the figure so that it does not deform.

INSTALLATION
1. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to between pad and shim. Install shim, shim cover, to pad.





2. Apply PBC (Poly Butyl Cuprysil) grease or silicone-based grease to between pad retainer and pad. Install pad retainers and pads to torque member.

CAUTION:
^ Securely assemble pad retainers so that they are not being lifted up from torque member.
^ Both inner and outer pads have a pad return system on the pad retainer. Install pad return lever securely to pad wear sensor.


3. Install cylinder body to torque member.

CAUTION: In the case of replacing a pad with new one, check a brake fluid level in the reservoir tank because brake fluid returns to master cylinder reservoir tank when pressing piston in.

NOTE: Use a disc brake piston tool (commercial service tool) to easily press piston.

4. Install lower sliding pin bolt, and tighten it to the specified torque. Refer to "Component".
5. Check front disc brake for drag.
6. Install tires to vehicle.
