(12) Remove vacuum seal located on the mounting
flange of the master cylinder. The vacuum seal is
removed from master cylinder by carefullypulling it
off the rear of master cylinder. Do not attempt to
pry the seal off the master cylinder by inserting
a sharp tool between seal and master cylinder
casting.
REMOVAL - RHD
CAUTION: Vacuum in the power brake booster must
be pumped down (removed) before removing mas-
ter cylinder from power brake booster. This is nec-
essary to prevent the power brake booster from
sucking in any contamination as the master cylin-
der is removed. This can be done simply by pump-
ing the brake pedal, with the vehicle's engine not
running, until a firm feeling brake pedal is achieved.
(1) With engine not running, pump brake pedal
until a firm pedal is achieved (4 or 5 strokes). (2) Disconnect negative battery terminal.
(3) Disconnect positive battery terminal.
(4) Remove battery shield.
(5) Remove nut and clamp securing battery to tray,
remove battery. (6) Thoroughly clean all surfaces of the brake fluid
reservoir and master cylinder. Use only solvent such
as Mopar tBrake Parts Cleaner or equivalent.
(7) Remove wiring harness connector from brake
fluid level switch in master cylinder brake fluid res-
ervoir (Fig. 46). (8) Disconnect primary and secondary brake tubes
from master cylinder housing (Fig. 50). Install seal-
ing plugs in the now open brake tube outlet ports. CAUTION: Before removing the master cylinder
from the power brake vacuum booster, the master
cylinder and vacuum booster must be thoroughly
cleaned. This must be done to prevent dirt particles
from falling into the power brake vacuum booster.
(9) Clean area where master cylinder assembly
attaches to power brake booster. Use only a solvent
such as Mopar tBrake Parts Cleaner or equivalent.
(10) Remove two nuts attaching master cylinder to
power brake booster (Fig. 50). (11) Slide master cylinder straight out of power
brake booster.
CAUTION: A seal on the rear of the master cylinder
is used to create the seal for holding vacuum in the
power brake vacuum booster. The vacuum seal on
the master cylinder MUST be replaced whenever the
master cylinder is removed from the power brake
vacuum booster.
(12) Remove vacuum seal located on the mounting
flange of the master cylinder. The vacuum seal is
removed from master cylinder by carefullypulling it
off the rear of master cylinder. Do not attempt to
pry the seal off the master cylinder by inserting
a sharp tool between seal and master cylinder
casting.
DISASSEMBLY - MASTER CYLINDER (FLUID
RESERVOIR)
(1) Clean master cylinder housing and brake fluid
reservoir. Use only a solvent such as Mopar Brake
Parts Cleaner or an equivalent.

(2) Remove brake fluid reservoir cap. Using a
syringe or equivalent type tool empty as much brake
fluid as possible from the reservoir.
CAUTION: When removing fluid reservoir from the
master cylinder, do not pry off using any type of
tool. This can damage the fluid reservoir or master
cylinder housing.
(3) Remove the master cylinder assembly from the
power brake vacuum booster. (Refer t o 5 - BRAKES -
BASE/HYDRAULIC/MECHANICAL/MASTER CYL-
INDER - REMOVAL). (4) Mount the master cylinder in a vise using the
master cylinder mounting flange. (5) Using correct size pin punch, remove the two
retaining pins between the fluid reservoir and master
cylinder housing (Fig. 51).
(6) Rock the brake fluid reservoir from side to side
while pulling up to remove it from the seal grommets
in master cylinder housing. (7) Remove the two master cylinder housing to
brake fluid reservoir seal grommets (Fig. 52).
ASSEMBLY - MASTER CYLINDER (FLUID
RESERVOIR)
(1) Install new master cylinder housing to brake
fluid reservoir sealing grommets in master cylinder
housing (Fig. 52). (2) Lubricate reservoir mounting area with fresh
clean brake fluid. Place reservoir in position over
sealing grommets. Seat reservoir into sealing grom-
mets using a rocking motion while firmly pressing
down on fluid reservoir. (3) Be sure fluid reservoir is positioned properly on
master cylinder. Bottom of fluid reservoir is to be touching the top of both sealing grommets
when properly installed on master cylinder
housing.
(4) Install the two fluid reservoir to master cylin-
der retaining pins (Fig. 51). (5) Install the master cylinder assembly on the
power brake booster. (Refer t o 5 - BRAKES/HY-
DRAULIC/MECHANICAL/MASTER CYLINDER -
INSTALLATION) (6) Fill fluid reservoir to its proper level as indi-
cated on the side of the fluid reservoir.

INSTALLATION - LHD
CAUTION: Different types of master cylinders are
used on this vehicle depending on brake options. If
a new master cylinder is being installed, be sure it
is the correct master cylinder for the type of brake
system the vehicle is equipped with.
CAUTION: When replacing the master cylinder on a
vehicle, a NEW vacuum seal MUST be installed on
the master cylinder.
(1) Install a NEW vacuum seal on master cylinder
making sure seal fits squarely in groove of master
cylinder casting. (2) Position master cylinder on studs of power
brake booster, aligning booster push rod with master
cylinder piston. (3) Install the two master cylinder mounting nuts
(Fig. 49). Tighten both mounting nuts to a torque of
25 N´m (225 in. lbs.).

CAUTION: When tightening the primary and sec-
ondary brake tube nuts at master cylinder, be sure
brake tubes do not contact any other components
within the vehicle and that there is slack in the flex-
ible sections of the tubes. This is required due to
the movement between the ABS ICU and the master
cylinder while the vehicle is in motion.(4) Connect primary and secondary brake tubes to
master cylinder primary and secondary ports (Fig.
48). Brake tubes must be held securely when tight-
ened to control orientation of flex section. Tighten

POWER BRAKE BOOSTER
DESCRIPTION
The power brake booster mounts on the engine
compartment side of the dash panel. It is connected
to the brake pedal by the input (push) rod (Fig. 64).
The master cylinder is bolted to the front of the
booster. A vacuum line connects the power brake
booster to the intake manifold.
All Left-Hand-Drive (LHD) vehicles use a 270 mm
single diaphragm vacuum power brake booster. All
Right-Hand-Drive (RHD) vehicles use a 225/200 mm
tandem diaphragm vacuum power brake booster. Vehicles equipped with Disc/Disc brakes use a dif-
ferent power brake booster than vehicles equipped
with Disc/Drum brakes. Differences between the two
are internal. Service is the same for all boosters. The power brake booster can be identified by the
tag attached to the body of the booster (Fig. 65). This
tag contains the production part number, the date it
was built, and who the manufacturer of the power
brake booster is.
