Do not reuse copper sealing washers.
5. Remove the lock plate and remove the brake hose.
INSTALLATION
CAUTION:
Do not allow foreign matte r (e.g., dust) and oils other than brake fluid to enter the reservoir tank.
1. Assemble the union bolt (A) and the copper sealing washers (1) to the brake hose and install it as an assembly to the brake cali-
per. Align the brake hose L-pin by aligning it with the brake cali-
per hole, and tighten the union bolt (A) to the specified torque.
CAUTION:
Do not reuse copper sealing washers.
2. Install the brake pipe to the brake hose, temporarily tighten the flare nut by hand until it does not rotate further, and attach the
brake hose to the bracket with the lock plate.
CAUTION:
Check that the brake hoses and pipes are not bent or
twisted.
3. Connect brake hose (1) to brake tube (2). Tighten flare nut (A) to specification and secure to the bracket with lock plate (3).
4. Refill with new brake fluid and perform air bleeding. Refer to BR-
14, "Bleeding Brake System".
CAUTION:

CAUTION:
• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is
splashed on painted areas, wash it away with water immediately.
• Do not scratch the piston of master cylinder when installing/removing because the piston is
exposed. Check for any dust on the piston , and wash with brake fluid if needed.
• Hold the master cylinder body when handing the master cylinder assembly. Do not hold the piston
because the piston might become detached if pulled strongly.
• Refill the reservoir tank wi th new brake fluid “DOT 3”.
• Do not reuse drained brake fluid.
• Do not reuse master cylinder O-ring.
NOTE:
When removing components such as hoses, tubes/lines, etc. , cap or plug openings to prevent fluid from spill-
ing.

WARNING:
Clean dust on brake calipers and brake pads with a vacuum dust collector to minimize the hazard of
airborne particles or other materials.
CAUTION:
• While removing brake caliper, do not depr ess brake pedal because piston will pop out.
• It is not necessary to remove bolts from torque member and brake hose except for disassembly or
replacement of brake caliper assembly. In this case, hang brake caliper with a wire so as not to
stretch brake hose.
• Do not damage piston boot.
• Keep brake rotor and brake pads free from brake fluid and grease.
• Burnish the brake pads and disc brake rotor mutual ly contacting surfaces after refinishing or replac-
ing disc brake rotors, after replacing brake pads, or if a soft pedal occurs at very low mileage. Refer
to BR-16, "Brake Burnishing"
.
