CHECK AND ADJUSTMENT OF PARKING
BRAKE
1. CHECK THAT PARKING BRAKE LEVER TRAVEL IS
CORRECT
Pull the parking brake lever all the way up, and count the num-
ber of clicks.
Parking brake levertravel at 20 kg (44.1 Ib, 196 N):
5 ± 8 clicks
If incorrect, adjust the parking brake.
2. IF NECESSARY, ADJUST PARKING BRAKE LEVER
TRAVEL
HINT: Before adjusting the parking brake, make sure that the
rear brake shoe clearance has been adjusted.
For shoe clearance adjustment, see steps 8 and 9 on page
BR±32 or step 8 on page 48.
(a) Remove the console box.
(b) Loosen the lock nut and turn the adjusting nut until the
lever travel is correct.
(e) Tighten the lock nut.
Torque: 55 kg±cm (48 in.±Ib, 5.4 N±m)
(d) Install the console box. 3. BEGIN BLEEDING AIR FROM BRAKE OR WHEEL
CYLINDER WITH LONGEST HYDRAULIC LINE
(a) Connect the vinyl tube to the brake or wheel cylinder
bleeder plug, and insert the other end of tube in a
halffull container of brake fluid.
(b) Slowly pump the brake pedal several times.
(c) While having an assistant press on the pedal, loosen
the bleeder plug until fluid starts to runout. Then close
the bleeder plug.
(d) Repeat (b) and (c) until there are no more air bubbles
in the fluid.
(e) Tighten the bleeder plug.
Bleeder plug tightening torque:
85 kg±cm (74 in.±!b, 8.3 N±m)
4. REPEAT PROCEDURE FOR EACH WHEEL(c) Block off the outer holes with your fingers, and re-
lease the brake pedal.
(d) Repeat (b) and (c) three or four times.

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 MASTER CYLINDER
(See page BR±9)
1. CLEAN OUT GROOVE ON LOWER INSTALLATION
SURFACE OF MASTER CYLINDER
2. CONFIRM THAT ºUPº MARK ON MASTER CYLINDER
BOOT IS IN CORRECT POSITION
5. CONNECT BRAKE TUBES
Using SST, connect. the brake tubes to the master cylin-
der.
Torque the union nuts.
SST 09751±36011
Torque: 155 kg±cm (11 ft±ib, 15 N ± m)
4. INSTALL MASTER CYLINDER
Set the new gasket and install the master cylinder, clamp
and 3±way union on the brake booster with three nuts.
Torque: 130 kg±cm (9 ft±Ib, 13 N¿ m)
3. ADJUST LENGTH OF BRAKE BOOSTER PUSH ROD
BEFORE INSTALLING MASTER CYLINDER
(See page BR±16)

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.
SST 49737±00010
(c) Measure the clearance between the booster push
rod and pin head (SST).
Clearance: 0 mm (0 in.)
2. INSTALL BRAKE BOOSTER, GASKET AND CLEVIS
(a) Install the clevis lock nut and clevis to the brake
booster.
(b) Install the brake booster and gasket.
(c) Install and torque the booster mounting nuts.
Torque: 130 kg±cm (9 ft±Ib, 13 N¿ m)
(d) Adjust the booster push rod length until the push rod
lightly touches the pin head.
