CAUTION
When servicing brake assemblies or components, do not create dust by sanding, grinding or by cleaning
brake
parts with a dry brush or with compressed air. A WATER DAMPENED CLOTH SHOULD BE USED.
Many brake components contain asbestos fibers which can become air-borne if dust is.created duringservice operations. Breathing dust which contains asbestos fibers can cause serious bodily harm.

PROPORTIONING VALVE FUNCTION TEST
NO!iR(r
1.Connect two pressure gauges, one each to the input sid
and output side of the proportioning valve, as shown,
2. Air bleed the brake line and the pressure gauge.
3. While gradually depressing the brake pedal, make th
following measurements and check to be sure that th
measured values are within the allowable range.
(1) Output pressure begins to drop relative to inpl
pressure (split point).
Standard value:
3.95-4.45 MPa (561-633 psi
3.45-3.95 MPa (491-561 ps(2) Output fluid pressure when input fluid pressure are a
follows.
Standard value:
5.15-5.65 MPa (732-804 ps[at 8.2
MPa (1,163 psi))
4.65-5.15 MPa (661-732 ps[at 7.7
MPa (1,095 psi)]
(3) Output pressure difference between left and
rig1brake lines
Limit: 0.4
MPa (57 psi)
4. If the measured pressures are not within the permissibl
ranges, replace the proportioning valve.
BLEEDINGNo5FYWhen the master cylinder is empty of brake fluid, bleed i
from the master cylinder by proceeding with procedures
(thru (6). (Because this master cylinder is not equipped with
check valve.)
When brake fluid remains in the master cylinder, proceed wi
step (6).
(1) Disconnect the brake tube from the master cylinder.
(2) Two
persqs should conduct the air bleeding, one persoslowly depressing the brake pedal and holding the
ped:

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
.in the thick-
nesses of the pads
