REASSEMBLY
CALIPER ASSEMBLY


Reassembly Steps
▲ 1. Body; caliper
▲ 2. Ring seal
▲ 3. Dust seal; piston
▲ 4. Piston
▲ 5. Bleeder
▲ 6. Cap






Important Operations
1. Body; Caliper
2. Ring Seal
Apply clean brake fluid to the ring seal and cylinder wall, then
insert the ring seal into the cylinder.
Ensure that the piston ring seal are not twisted in the calipe
r
bore grooves.

3. Dust seal; Piston
• Apply grease to piston groove and dust seal boot.
1) Make sure a piston and its groove area are free from dust.
2) Use 0.5g to apply grease to groove area thoroughly using a brush or finger.
Make sure color of groove changes as shown bello
w
after apply grease.





3) After assembling a dust seal boot to the piston, apply
1.5g to contact area of the piston and the dust seal boot
as shown in the picture bellow.

4. Piston
Apply clean brake fluid to the piston, and attach the caliper.
W hen inserting the piston into the cylinder, use finger pressure
only. Do not use a mallet or other impact tool, since damage to
the cylinder wall or ring seal can result.
The movement of a caliper piston into a caliper bore should be
smooth and even. If a caliper piston is frozen or difficult to
move to the bottom, the caliper requires overhaul o
r
replacement.
RTW 35CSH000701
W hen not entering with a finger, insert a discarded inner brake
pad (2) or block of wood in front of the pistons. Using 2 large
C-clamps (1) installed over the body of the caliper (3) and
against the brake pad or block of wood, slowly move the
pistons evenly into the bores.
Insert the dust seal ring into the dust seal.
CAUTION:
Pistons made of plastic material.
Do not hit the piston with a hammer etc. and don’t grasp
the face of the piston with pliers.

Clean wheel Cylinder Parts
Always use clean brake fluid to clean wheel cylinder parts.
Note:
Do not use mineral based cleaning solvents such as
gasoline, kerosene, acetone, paint thinner, or carbon
tetrachloride.



Piston Cups
Inspect the piston cups for wear, distortion, fatigue or other
abnormal conditions.

Important Operations
Note:
• W ash the disassembled parts in clean brake fluid.
• Use compressed air to clean the ports.
• Protect the disassembled part surfaces from contamination
by dust and other foreign material.
• Before reassembly, check the part surfaces fo
r
contamination with dust or other foreign material.
• Be sure to replace the designated parts with new ones.

1. Piston Assembly
Install new piston cups on each piston so that the flared end of
the cups are turned to the inboard side of the pistons.
Attach the return spring and the boot to the piston.
Be sure to use new piston cup and boot.

•
Apply brake fluid to the pistons and the inner face of the
boots.
• Note the direction of piston cup (1).
• Apply rubber grease to the boots (2) as shown in the
illustration.
