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 or DOT4
Caution
1.Use the specified brake fluid. Avoid using a mixtureof 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, be
sure 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
REPLACEMENTN05FOAF
NOTEThe brake pads have wear indicators that contact the brake
disc 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.Standard value: 10.0 mm
(.39 in.)
Limit: 2.0 mm
(.08 in.)
Caution
1. When the limit is exceeded, replace the pads at
both sides, and also the brake pads for the wheels
on the opposite side at the same time.
2. If there is a
significant difference

nesses of the pads

rection.
NOTE
Tighten the nuts in order to secure the disc to the hub.
5.Securely attach the pad clip to the caliper support.
6.Clean piston and insert into cylinder with tool.7. Be careful that the piston boot does not become
caughlwhen lowering the caliper assembly and install the guidt

1. Make sure that the friction surfaces of pads and
brake discs and free of grease and other contami-
nants.
2.The grease should never squeeze out from around

(3) Use a spring balance to meastiie fh-e rotation Sliding re-
sistance of the hub in the forward direction.(4) Calculate the drag torque of the disc brake (difference
between measured values in 3 and 4).Standard value: 70
N (15.4 Ibs.) or less
10. If the disc brake drag force exceeds
tlie standard value,
disassemble piston and clean the piston. Check for corro-
sion or worn piston seal, and check the sliding condition of
the lock pin and guide pin.FRONT DISC BRAKE ROTOR INSPECTION
CAUTIONWhen servicing disc brakes, it is necessary to exercise caution to keep the disc brakes within the
allowable service values in order to maintain normal brake operation.
Before re-finishing or re-processing the brake disc surface, the following conditions should be checked.
Inspection itemsRemarks
Scratches, rust, saturated lining materials
and wearlIf the vehicle is not driven for a certain period, the sections of the discsthat are not in contact with lining will become rusty, causing noise and
shuddering.
lIf grooves resulting from excessive disc wear and scratches are not re-moved prior to installing a new pad assembly, there will momentarily
beinappropriatecontact between the disc and thelining(pad).
Run-out or drift
Ehange in thickness (parallelism)Excessive run-out or drift of the discs will increase the pedal depression
resistance due to piston knock-back.
If the thickness of the disc changes, this will cause pedal pulsation, shud-
deringand surging.

14A0391
RUN-OUT CHECK
1.Remove the caliper support; then raise the caliper ass
bly upward and secure by using wire.
2.Inspect the disc surface for grooves, cracks, and rust. Cl
the disc throughly and remove all rust.3. Place a dial gauge approximately 5 mm
(.2 in.) from thiouter circumference of the brake disc, and measure
tt$
run-out of the disc._iLimit: 0.07 mm
(.0028 in.)-2
NOTE
Tighten the nuts in order to secure the disc to the hub..‘l;i,!
..,;RUN-OUT CORRECTION
NOSFTAB
1.If the run-out of the brake disc is equivalent to or exceeds
the 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
2s
shown in the illustration; then move the hub in the axial
direction and measure the play.Limit: 0.2 mm
(.008 in.)
If the play is equivalent to or exceeds the limit, disas-
semble the hub knuckle and check each part.
2.(3) If the play does not exceed the limit specification, and
then check the run-out of the brake disc once again.
Mount the brake disc on the position dislocated from
the chalk mark.If the run-out cannot be corrected by changing the phase
of the brake disc, replace the disc or turn rotor with on the
car type brake lathe (MAD DL-8700PF or equivalent).’
