REMOVAL
CAUTION:

Do not allow brake fluid to spill or splash on painted surfaces. Brake fluid can seriously damage
paint. If it gets on a painted surface, wipe it off immediately and wash it away with water.

Do not bend or twist brake hose sharply, or strongly pull it.

Cover brake fluid line joints to prevent dust and other foreign material.
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve of each wheel while depressing brake pedal.
3. Using a flare nut wrench, remove brake tube flare nuts and dis-
connect brake tube from brake hose.
4. Remove lock spring.
INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3” or “DOT 4”.

Never reuse drained brake fluid.
1. Connect brake hose to the brake tube. Temporarily tighten flare nut by hand as far as it will go.
2. Fix brake hose by lock plate.

Disassembly
CAUTION:
Remove master cylinder reservoir tank only when necessary.
1. Using a slotted flat-bladed screwdriver as shown in the figure,
lever up stopper cap tabs and remove stopper cap. While
removing, be sure to hold cap securely to prevent the master
cylinder piston from popping out.
2. Secure cylinder body flange in a vise as shown in the figure.
CAUTION:

Secure cylinder body flange with chamfered pin insert
hole, facing upward.

When securing in the vise, use copper plates or cloth to
protect the flange.
3. Using a pin punch [tool: diameter Approx. 4 mm (0.16 in)],
remove reservoir tank mounting pins.
4. Remove master cylinder assembly from the vise.
5. Remove reservoir tank and grommet from the cylinder body.
6. Using a Phillips flat-bladed screwdriver, press and hold piston
pin as shown in the figure. Remove piston stopper from the cyl-
inder body.
7. Carefully pull primary piston assembly straight out to prevent
damage to the cylinder inner wall.
8. Tap flange against a wood block to loosen secondary piston
assembly. Carefully pull secondary piston assembly straight out
to prevent damage to the cylinder inner wall.
Inspection After Disassembly

Check cylinder inner wall for damage, wear, corrosion, and pinholes. Replace cylinder if damage, wear, or
corrosion is detected.

Disassembly (Piston Assembly)
1. Using a flat-bladed screwdriver as shown in the figure, lift up the
tabs on the stopper cap and remove it from the master cylinder.
NOTE:
Remove stopper cap while holding it because the piston in mas-
ter cylinder may pop out.
2. Carefully pull primary piston assembly straight out to prevent the
cylinder inner wall from being damaged.
3. Tap flange using a soft block, such as wood, and carefully pull
secondary piston assembly straight out to prevent cylinder body
inner wall from being damaged.
Inspection After Disassembly (Piston Assembly)
Cylinder body

Check inner wall of cylinder for damage, abrasion, corrosion, and pinholes. Replace the cylinder body if
detected.
Assembly (Piston Assembly)
CAUTION:

Do not use mineral oils such as kerosene, gasoline during the cleaning and assembly process.

Make sure there is no foreign matter such as dirt or dust attached to the inner cylinder walls, the
piston, or the cap seal, and use care to avoid damaging parts with the assembly tools.

Do not drop parts. If a part is dropped, do not use it.
1. Apply fluid to cylinder inner wall body and contact surface of the
piston assembly. Then insert secondary piston assembly and
primary piston assembly into cylinder body in this order.
CAUTION:

Pay attention to the orientation of the piston cup, and
insert straight to prevent the cup from being caught by
cylinder inner wall.

Be sure to replace the assembly without disassembling
the new inner kit.

Do not reuse the primary and secondary piston assem-
blies.
