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.
