the paint; if brake fluid does contact the paint, wash

it off immediately with water.

• To prevent spills, cover the hose joints with rags or

shop towels.

• Clean all parts in brake fluid and air dry; blow out all

passages with compressed air.

Reassembly

Never use an air hose or dry brush to clean brake assemblies.

Use an OSHA-approved vacuum cleaner to avoid breathing brake dust.

Contaminated brake discs or pads reduce stopping ability.

When reusing the pads. Install them in their original positions to prevent loss of braking efficiency.

CAUTION:

Do not spill brake fluid on the vehicle; It may damage the paint; if brake fluid does contact the paint, wash it off imme-

diately with water.

Clean all parts in brake fluid and air dry; blow out all passages with compressed air.

Before reassembling, check that all parts are free of dust and other foreign particles.

Replace parts with new ones whenever specified to do so.

Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.

Always use Genuine Honda DOT 3 Brake Fluid. Using a non-Honda brake fluid can cause corrosion and decrease the

life of the system.

NOTE:

Coat piston, piston seal groove, and caliper bore with clean brake fluid.

Replace all rubber parts with new ones whenever disassembled.

: Use recommended silicone greases in the caliper seal set.

: Use recommended rubber grease in the caliper seal set.
