INSPECTION OF MASTER CYLINDER
COMPONENTS
HINT: Clean the disassembled parts with compressed air.
1. INSPECT CYLINDER BORE FOR RUST OR SCORING
2. INSPECT CYLINDER FOR WEAR OR DAMAGE
If necessary, clean or replace the cylinder.
DISASSEMBLY OF MASTER
CYLINDER
1. REMOVE RESERVOIR
(a) Remove the set screw and pull out the reservoir.
(b) Remove the cap and strainer from the reservoir.
2. REMOVE TWO GROMMETS
3. PLACE CYLINDER IN VISE
5. REMOVE TWO PISTONS AND SPRINGS
(a) Push in the piston with a screwdriver and remove the
snap ring with snap ring pliers.
(b) Remove the No. 1 piston and spring hand, pulling
straight out, not at an angle.
NOTICE: If pulled out at an angle, there is possibility of
damaging the cylinder bore.
(c) Place a rag and two wooden blocks on the work table
and lightly tap the cylinder flange against the blocks
until the piston drops out of the cylinder.
HINT: Make sure the distance (A) from the rag to the top
of the blocks is at least 100 mm (3.94 in.) 4. REMOVE PISTON STOPPER BOLT
Using a screwdriver, push the pistons in all the way and
remove the piston stopper bolt and gasket.
HINT: Tape the screwdriver tip before use.

2. INSTALL TWO SPRINGS AND PISTONS
CAUTION: Be careful not to damage the rubber lips on
the pistons.
(a) Insert the two springs and pistons straight in, not at
an angle.
NOTICE: If insert at an angle, there is possibility of damag-
ing the cylinder bore.
(b) Push in the piston with a screwdriver and install the
snap ring with snap ring pliers.
HINT: Tape the screwdriver tip before use.
3. INSTALL PISTON STOPPER BOLT
Using a screwdriver, push the piston in all the way and
install the piston stopper bolt over the gasket. Torque the
bolt.
Torque: 100 kg±cm (7 ft±Ib, 10 N±m)
ASSEMBLY OF MASTER CYLINDER
(See page BR±10)
1. APPLY LITHIUM SOAP BASE GLYCOL GREASE TO
RUBBER PARTS INDICATED BY ARROWS
4. INSTALL TWO GROMMETS
± BRAKE SYSTEMMaster CylinderBR±12

5. INSTALL RESERVOIR
(a) Install the cap and strainer to the reservoir.
(b) Push the reservoir onto the cylinder.
(c) Install the set screw while pushing on the reservoir.
Torque: 17.5 kg±cm (15.2 in.±Ib, 1.7 N±m)
NOTICE: Because the master cylinder and reservoir
tank union is a grommet type, the set screw is de-
signed to not separate the reservoir from the cylinder
and will not tighten down the reservoir. Therefore,
there is a clearance at point A. Do not insert washers
or an equivalent when tightening.

INSTALLATION OF BRAKE BOOSTER
(See page BR±15)
1. ADJUST LENGTH OF BOOSTER PUSH ROD
(a) Set the SST on the master cylinder with the gasket,
and then lower the pin until its slightly touches the
piston.
SST 09737±00010
3. CONNECT CLEVIS TO BRAKE PEDAL
Insert the clevis pin into the clevis and brake pedal, and
install the clip to the clevis pin.
4. INSTALL PEDAL RETURN SPRING
5. INSTALL INSTRUMENT LOWER FINISH PANEL(b) Turn the SST upside down and set it on the booster.

REPLACEMENT OF BRAKE PADS
HINT: If a squealing noise occurs from the front brakes
while driving, check the pad wear indicator. If there are
traces of the indicator contacting the rotor disc, the brake
pad should be replaced.
