SERVICE ADJUSTMENT PROCEDURES
BRAKE PEDAL INSPECTION AND ADJUSTM&g
1.Measure the brake pedal height as illustrated. If the brake
pedal height is not within the standard value, adjust as
follows.
Standard value (A): 176181 mm (6.9-7.1 in.)(1) Disconnect the stop light switch connector, loosen the
lock nut, and move the stop light switch to a position
where it does not contact the brake pedal arm.
(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) After screwing in the stop light switch until it contacts
the brake pedal stopper (just before the brake pedal is
caused to move), return the stop light switch
l/2 to 1turn and secure by tightening the lock nut.
(4) Connect the connector of the stop light switch.
(5) Check to be sure that the stop light is not illuminated
with the brake pedal unpressed.
Reference value (B): 0.5-1.0 mm
(.02-M in.)
2. 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 confirmthat the amount of movement before resistance is met
(the free play) is within the standard value range.
Standard value
(C): 3-8 mm (.l-.3 in.)
If the free play is less than the standard value, confirm thatthe clearance between the stop light switch and brake
pedal is within the standard value.
If the free play exceeds the standard value, it is probably
due to excessive play between the
clevis pin and brake
pedal arm. Check for excessive clearance and replace
faulty parts as required.
3. Start the engine, depress the brake pedal with approxi-
mately 500 N (110 Ibs.) of force, and measure the clearancebetween the brake pedal and the floorboard.
Standard value (D): 80 mm (3.1 in.) or moreIf the clearance is less than the standard value, check for
air trapped in the brake line and for brake fluid leaks. If
necessary, check the brake system mechanism (excessiveshoe clearance due to faulty auto adjuster) and repair
faulty parts as required.

BLEEDINGN65FYAN
When the master cylinder is empty of brake fluid, bleed air
from the master cylinder by proceeding with procedures (1)
thru (6). (Because this master cylinder is not equipped with a
check valve.)
When brake fluid remains in the master cylinder, proceed with
step (6).
(1) -Disconnect the brake tube from the master cylinder.
(2) Two persons should conduct the air bleeding, one person
slowly depressing the brake pedal and holding the pedal
depressed.(3) In this condition, the other person should use a finger to
close the outlet part of the master cylinder, and then the
first person should release the brake pedal.
(4) Steps (2) and (3) should be repeated three or four times,
and then the master cylinder should be filled with brake
fluid to the specified level.
NOTE
The air is completely bled from the master cylinder by steps
(1) to (4).
(5) Connect the brake tube to the master cylinder.
(6) Start the engine; then, in the sequence shown in the
illustration, bleed the air from each wheel cylinder.
Specified brake fluid: MOPAR Brake Fluid/
Conforming to DOT3
Caution
1.Use the specified brake fluid. Avoid using a mixture
of the specified brake fluid and other fluid.2. If brake fluid is exposed to the air, it will absorb
moisture; as water is absorbed from the atmos-phere, the boiling point of the brake fluid will
decrease and the braking performance will be
seriously impaired. For this reason, use a hermeti-
cally sealed 1 lit.
(1.06 qt.) or 0.5 lit. (0.52 qt.) brake
fluid container.3. Firmly close the cap of the brake fluid container
after use.
4. For vehicles with the anti-lock braking system, besure to install a filter to the master cylinder
reservoir tank when supplying brake fluid.
ORDINARY AIR-BLEEDING PROCEDURES(1) Depress the brake pedal several times until resistance is
felt; then, with the pedal depressed, loosen the bleeder
screw
l/3 to l/2 turn and then tighten it before the fluid
pressure is all gone.
(2) Release the brake pedal. Repeat this procedure until there
are no more air bubbles in the brake fluid.

FRONT DISC BRAKE PAD CHECK AND REPLACE-
MENiNWFOAF
NOTE
The brake pads have wear indicators that contact the brake discd’when the brake pad thickness becomes 2 mm
(.08 in.), and
emit a squealing sound to warn the driver.
1. Check brake pad thickness through caliper body check
port.Limit: 2.0 mm
(.08 in.)
Caution1. When the limit is exceeded, replace the pads at
both sides, and also the brake pads for the wheelson the opposite side at the same time.
2.If there is a significant difference in the thicknesses
of the pads on the left and right sides, check the
sliding condition of the piston, lock pin sleeve and
guide pin sleeve.
2.Remove lock or guide pin. Lift caliper assembly and retain
with wires.
Caution
Do not wipe off the special grease that is on the guide
-pin or allow it to contaminate the guide pin.
3. Remove the following parts from caliper support.

when lowering the caliper assembly and install the guide
pin.8. Check brake drag torque as follows.
(1) Start engine and hold brake pedal down for 5 seconds.
(2) Stop engine.
(3) Turn brake disc forward
10 times.
(4) Check brake drag torque with spring scale.
If the difference between brake drag torque and hub torqueexceeds the standard value, disassemble piston and clean

1.If the run-out of the brake disc is equivalent to or exceeds 5the limit specification, change the phase of the disc and
-’hub, and then measure the run-out again.
(1) Before removing the brake disc, chalk both sides of the
wheel stud on the side at which run-out is greatest.
(2) Remove the brake disc, and then place a dial gauge as
shown in the illustration; then move the hub in the axialdirection and measure the play.
Limit: 0.008 mm
(00031 in.)
If the play is equivalent to or exceeds the limit,
disassemble the hub knuckle and check each part.
(3) If the play does not exceed the limit specification, and
then check the run-out of the brake disc once again.
