Handling the Brake Parts

WARNING: 

Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.

• Avoid breathing dust particles.
• Never use a compressed air gun (unless specified) to clean brake assemblies. Use an OSHA-approved vacuum cleaner.

• Clean all parts with brake cleaner and air dry.
• Before reassembling, check that all the parts are free of dirt and other foreign particles.
• Replace parts with new ones whenever specified to do so.
• Make sure no grease or oil gets on the brake discs, the brake drums, the brake pads, or the brake shoes.
• Before installing the brake disc or the brake drum, clean the mating surfaces between the hub or hub bearing unit and the inside of the brake disc or the brake drum.
• After removing the brake hoses and the brake lines, plug the ends of the hoses and the joints to prevent spilling brake fluid.
• Be careful not to bend, damage, or deform the brake lines.
• After installing the brake hoses, check the brake hoses for interference and twisting.
• During brake caliper removal, to prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage.
• Be careful when pressing or moving the piston back in the caliper; brake fluid might overflow from the master cylinder's reservoir. If brake fluid gets on any painted surface, wash it off immediately with water.
