Brake Pedal
Checking Pedal Height
The push rod serves as the brake pedal stopper when the
pedal is fully released. Brake pedal height adjustment
should be performed as follows:
Adjust Brake Pedal
310RY00004
1. Measure the brake pedal height after making sure the
pedal is fully returned by the pedal return spring.
Pedal height must be measured after starting the
engine and receiving it several times.
Pedal Free Play: 6-10 mm (0.23-0.39 in)
Pedal Free Play: 173-185 mm (6.81-7.28 in)
NOTE: Pedal free play must be measured after turning
off the engine and stepping on the brake pedal firmly five
times or more.
2. If the measured value is not within the above range,
adjust the brake pedal as follows:
a. Disconnect the stoplight switch connector.
b. Loosen the stoplight switch lock nut.
c. Rotate the stoplight switch so that it moves away
from the brake pedal.
d. Loosen the lock nut (1) on the push rod.
e. Adjust the brake pedal to the specified height by
rotating the push rod in the appropriate direction.
f. Tighten the lock nut to the specified torque.
Torque: 20 N´m (15 lb ft)
g. Adjust the stoplight switch (2) to the specified
clearance (between the switch housing and the
brake pedal) by rotating the switch housing.
Clearance: 0.5±1.0 mm (0.02±0.04 in)
310RY00005
NOTE: While adjusting the stoplight switch, make sure
that the threaded part of the stoplight switch does not
push the brake pedal.
h. Tighten the stoplight switch lock nut.
i. Connect the stoplight switch connector.
Checking Pedal Travel
310RY00004
1. Pedal height must be measured after starting the
engine and revving it several times to apply vacuum
to the vacuum booster fully.
NOTE: Pedal height must be 95 mm (3.7 in) or more
when about 50 kg (110.25 lb) of stepping force is applied.
2. If the measured value is lower than the above range,
air may still be present in the hydraulic system
Perform the bleeding procedure.

Removal
CAUTION: When removing the master cylinder from
the vacuum booster, be sure to get rid of the internal
negative pressure of the vacuum booster (by, for
instance, disconnecting the vacuum hose) in
advance.
If any negative pressure remains in the vacuum
booster, the piston may possibly come out when the
master cylinder is being removed, letting the brake
fluid run out.
While removing the master cylinder, further, do not
hold the piston as it can be easily pulled out.
Outside surface of the piston is the surface on which
seals are to slide. Care should be taken to keep the
surface free of cuts and dents.
1. Disconnect electrical connector.
2. Remove brake pipes and after disconnecting the
brake pipe, cap or tape the openings of the brake pipe
to prevent the entry of foreign matter.
3. Remove 2 attaching nuts.
4. Remove P&B valve and bracket.5. Remove master cylinder.
6. Remove spacer and the 2 gaskets.
Inspection and Repair
Master Cylinder
The master cylinder is not repairable and must be
replaced as a complete assembly if found defective.
Inspection
Excessive brake pedal travel, malfunction or dragging
brake suggests that the master cylinder is defective. In
such cases perform the following visual check:
Visual Check
Make parts replacement as required if wear, distortion,
nicks, cuts, corrosion, or other abnormal conditions are
found through the following parts inspection:

Piston
Push the primary piston (1) with your fingers to check that
it travels smoothly. If the motion is questionable, replace
the master cylinder as a complete assembly.
330RW007
Functional Inspection of Master Cylinder
Inspect the master cylinder for functionality described
below. Replace if necessary.
Install the primary piston holder (3) J±39242 (including
the master cylinder attachment (5) and master cylinder
plug (7)) onto the master cylinder (4). Make sure the
spacer (2) (2 bolts) with its adjusting bolt is screwed in up
to the ª0º line
330RW008Connect the master cylinder attachment (5) J±39242 with
the end of the radiator cap tester (6) J±24460±01, and
apply air pressure with the cap tester. Make sure there is
no rise in pressure while adjusting the bolt to the ª5º line.
There should be a pressure increase of 0.5 kg/cm

NOTE:
1. Do not use an air compressor, as the air from the
compressor is mixed with compressor oil.
2. When installing the master cylinder onto the vacuum
booster, always adjust the vacuum booster push rod.
(Refer to
Vacuum Booster in this section).
3. After the master cylinder is installed onto the vehicle,
check for leakage, pedal travel and pedal free play.
Installation
1. Install spacer and the 2 gaskets.
2. Install master cylinder.
When replacing the master cylinder or vacuum
booster or both, always measure the vacuum booster
push rod protrusion and adjust it as necessary (Refer
to
Vacuum Booster in section).
3. Install P&B valve and bracket.
4. Install 2 attaching nuts and tighten the attaching nuts
to the specified torque.
