SERVICE PROCEDURES
MASTER CYLINDER FLUID LEVEL CHECK
Check master cylinder reservoir fluid level a mini-
mum of twice annually.
Master cylinder reservoirs are marked with the
words FULL and ADD to indicate proper brake fluid
fill level of the master cylinder (Fig. 26).
If necessary, add brake fluid to bring the level to
the bottom of the FULL mark on the side of the mas-
ter cylinder fluid reservoir. When filling master
cylinder fluid reservoir do not fill the filler
neck of the fluid reservoir (Fig. 26) with brake
fluid.
Fig. 26 Master Cylinder Fluid Level Marks
Use only Mopar brake fluid or an equivalent from
a sealed container. Brake fluid must conform to DOT
3, specifications.
DO NOT use brake fluid with a lower boiling
point, as brake failure could result during prolonged
hard braking.
Use only brake fluid that was stored in a tightly-
sealed container.
DO NOT use petroleum-based fluid because seal
damage will result. Petroleum based fluids would be
items such as engine oil, transmission fluid, power
steering fluid ect.
BLEEDING BASE BRAKE HYDRAULIC SYSTEM
NOTE: This bleeding procedure is only for the vehi-
cle's base brakes hydraulic system. For bleeding
the antilock brakes hydraulic system, refer to the
ITT Teves Mark 20 Antilock Brake System bleeding
procedure in the antilock brakes section of this ser-
vice manual.
PRESSURE BLEEDING PROCEDURE
CAUTION: Before removing the master cylinder
cover, throughly clean the cover and master cylin-
der fluid reservoir to prevent dirt and other foreign
matter from dropping into the master cylinder fluid
reservoir.
CAUTION: Use bleeder tank Special Tool C-3496-B
with adapter Special Tool 6921 to pressurize the
hydraulic system for bleeding.
CAUTION: When pressure bleeding the brakes
hydraulic system the fluid reservoir filler neck must
be removed from the master cylinder fluid reservoir.
Failure to remove the filler neck from the fluid res-
ervoir, may result in the filler neck separating from
the fluid reservoir when the hydraulic system is
pressurized.
Follow pressure bleeder manufacturer's instruc-
tions, for use of pressure bleeding equipment.
When bleeding the brake system, some air may be
trapped in the brake lines or valves far upstream, as
much as ten feet from the bleeder screw (Fig. 27).
Therefore, it is essential to have a fast flow of a large
volume of brake fluid when bleeding the brakes to
ensure all the air gets out.
Fig. 27 Trapped Air In Brake Fluid Line
(1) Remove the filler neck from the master cylin-
der fluid reservoir.
(2) Install the Adapter Master Cylinder Pressure
Bleed Cap, Special Tool 6921 on the fluid reservoir of
the master cylinder (Fig. 28). Attach the fluid hose
from the pressure bleeder to the fitting on Special
Tool 6921.
(3) Attach a clear plastic hose to the bleeder screw
at one wheel and feed the hose into a clear jar con-
taining fresh brake fluid.
