BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air in the brake lines
is suspected, bleed the system of air.
NOTICE:
Do not let brake fluid remain on painted surfaces. Wash it
off immediately.
1. REMOVE RESERVOIR CAP
2. FILL RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS No.116DOT3
3. BLEED MASTER CYLINDER
HINT:
If the master cylinder has been disassembled or if the reservoir
becomes empty, bleed the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outer holes with your fingers, and release the
brake pedal.
(d) Repeat (b) 3 or 4 times.
4. BLEED BRAKE LINE
(a) Connect the vinyl tube to the brake caliper.
(b) Depress the brake pedal several times, then loosen the
bleeder plug with the pedal held down.
(c) At the point when fluid stops coming out, tighten the
bleeder plug, then release the brake pedal.
(d) Repeat (b) and (c) until all the air in the fluid has been bled
out.
Torque: (Bleeder plug)
11 N´m (110 kgf´cm, 8 ft´lbf)

INSTALLATION
1. INSTALL BRAKE BOOSTER
(a) Install the booster and a new gasket.
(b) Install the clevis to the operating rod.
(c) Install and torque the booster installation nuts.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(d) Insert the clevis pin into the clevis and brake pedal, and
install the clip to the clevis pin.
(e) Install the pedal return spring.
2. ADJUST LENGTH OF BOOSTER PUSH ROD
(a) Install the gasket on the master cylinder.
(b) Set the SST on the gasket, and lower the pin until its tip
slightly touches the piston.
SST 09737-00010
(c) Turn the SST upside down, and set it on the booster.
SST 09737-00010
(d) Measure the clearance between the booster push rod
and pin head (SST).
Clearance: 0 mm (0 in.)
(e) Adjust the booster push rod length until the push rod light-
ly touches the pin head.
HINT:
When adjusting the push rod, depress the brake pedal enough
so that the push rod sticks out.
3. INSTALL PEDAL BRACKET STAY
(a) Install the pedal bracket stay.
(b) Install the bolt and nut.
(c) Install the steering column assembly (See page
SR-21).
4. INSTALL THESE PARTS

Vacuum hose

Master cylinder (See page BR-17)
5. FILL BRAKE RESERVOIR WITH BRAKE FLUID AND
BLEED BRAKE SYSTEM (See page BR-5)
6. CHECK FOR FLUID LEAKAGE
7. CHECK AND ADJUST BRAKE PEDAL
(See page BR-7)
8. DO OPERATIONAL CHECK (See page BR-18)

REPLACEMENT
1. REMOVE FRONT WHEEL
Remove the wheel and temporarily fasten the disc with the hub
nuts.
2. INSPECT PAD LINING THICKNESS
Check the pad thickness and replace pads if they are not within
specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE THESE PARTS
(a) Clip and 2 pins
(b) Anti-rattle spring
(c) 2 pads
(d) 2 pad spacers
(e) 2 anti-squeal shims
NOTICE:
The anti-rattle spring, clip and pad spacers can be used
again provided that they have sufficient rebound, no de-
formation, cracks or wear, and have had all rust, dirt and
foreign particles cleaned off.
4. CHECK DISC THICKNESS AND RUNOUT
(See page BR-39)
5. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti-squeal shims must be
replaced together with the pads.
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or equivalent.
HINT:

Always change the pads on one wheel at a time as there
is a possibility of the opposite piston flying out.

If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some brake fluid es-
cape.
