GENERAL
OUTLINE OF CHANGE

The service procedures for left-hand drive vehicles have been established as described below.

The service procedures for the front and rear disc brakes have been changed since they had been
replaced by a different type.
ON-VEHICLE SERVICE
BRAKE PEDAL CHECK AND ADJUSTMENT

1. Turn up the carpet, etc under the brake pedal.
2. Measure the brake pedal height as illustrated. If the brake
pedal height is not within the standard value, follow the
procedure below.
Standard value: 163.5 –166.5 mm
(1) Disconnect the stop lamp switch connector.
(2) Adjust the brake pedal height by turning the operating
rod with pliers (with the operating rod lock nut
loosened), until the correct brake pedal height is
obtained.
(3) Secure by tightening the lock nut of the operating
rod.
(4) Push the stop lamp switch in the direction of the
pedal stroke until it stops. (The switch will slide if
it is pushed firmly.)
(5) Lift up the pedal until the operating rod is fully
extended, and then slide the stop lamp switch back
to the required position. Adjust the position of the
switch by turning it until the distance shown in the
illustration is correct.
(6) Connect the connector of the stop lamp switch.
(7) Check that the stop lamp is not illuminated with the
brake pedal unpressed.
3. With the engine stopped, depress the brake pedal two
or three times. After eliminating the vacuum in the power
brake booster, press the pedal down by hand, and confirm
that the amount of movement before resistance is met
(the free play) is within the standard value range.

If the free play exceeds the standard value, it is probably
due to excessive play between the retaining ring bolt
and brake pedal arm.
Check for excessive clearance and replace faulty parts
as required.
4. Start the engine, depress the brake pedal with
approximately 490 N of force, and measure the clearance
between the brake pedal and the floorboard.
Standard value: 80 mm or more
If the clearance is outside the standard value, check for
air trapped in the brake line, clearance between the lining
and the drum and dragging in the parking brake.
Adjust and replace defective parts as required.
5. Turn back the carpet, etc.

engine side contacts the edge of the hexagonal part of the
fitting, and then secure by using the hose clip.
BCLEARANCE ADJUSTMENT BETWEEN BRAKE
BOOSTER PUSH ROD AND PRIMARY PISTON
Calculate clearance A from the B, C and D measurements.

Standard value: 0.65–0.85 mm
If the clearance is not within the standard value range, adjust
by changing the push rod length by turning the screw of
the push rod.
