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

CAUTION:

While removing brake pads, 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 body. In this case, hang caliper body with a wire so as not to stretch the brake hose.
Do not damage the 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 rotors and pads free from grease and brake fluid.
Burnish the brake contact surface after refinishing or replacing rotors, after replacing pads, or if a soft pedal occurs at very low mileage. Refer to "BRAKE BURNISHING ".
