Chrysler 1998 Voyager, Service Manual, Page: 137 / 1938

CAUTION: The master cylinder is used to create
the seal for holding vacuum in the vacuum booster.
The vacuum seal on the master cylinder MUST be
replaced with a NEW seal whenever the master cyl-
inder is removed from the vacuum booster.
CAUTION: When removing the vacuum seal from
the master cylinder do not use a sharp tool.
(7) Using a soft tool such as a trim stick, remove
the vacuum seal from the master cylinder mounting
flange.
(8) Install a NEW vacuum seal on mounting flange
of the master cylinder (Fig. 128).
(9) Position master cylinder on studs of vacuum
booster, aligning push rod on vacuum booster with
master cylinder piston.
(10) Install the 2 nuts mounting the master cylin-
der to the vacuum booster (Fig. 124). Tighten both
mounting nuts to a torque of 25 N·m (225 in. lbs.).
(11) Install the wiper module drain hose (Fig. 124)
on the wiper module. Install the tie strap attaching
the wiper module drain hose to brake tube at the
master cylinder. Tie strap should be loosely tight-
ened so as not to collapse the wiper module
drain hose.
(12) Install the wiring harness connector on the
brake fluid level sensor in the master cylinder fluid
reservoir (Fig. 123).
(13) Install the throttle body and throttle cable
bracket on the intake manifold. Install the 2 bolts
(Fig. 122) attaching the throttle body to the intake
manifold and tighten to a torque of 25 N·m (225 in.
lbs.) Install clip (Fig. 122) attaching the wiring har-
ness to the throttle cable bracket.
(14) Install the wiring harness connectors on the
throttle position sensor and the AIS motor on throttle
body (Fig. 121).
(15) Install the wiring harness connector (Fig. 120)
on the EGR valve transducer.
(16) Install the battery tray. Install the 2 bolts and
the nut (Fig. 119) attaching the battery tray to the
vehicle. Tighten the 2 bolts and the nut to a torque of
14 N·m (125 in lbs.).
(17) If vehicle is equipped with speed control,
install the speed control servo and bracket on the
battery tray. Install and securely tighten bolt attach-
ing bracket to battery tray.
(18) If vehicle is equipped with speed control,
install the wiring harness connector on the speed
control servo. Then connect the vacuum lines onto
the speed control servo and vacuum reservoir on bat-
tery tray.
(19) Install the air inlet resonator and hoses as an
assembly on the throttle body and air cleaner hous-
ing (Fig. 118). Securely tighten hose clamp at air
cleaner housing and throttle body.
(20) Install the battery and the battery thermal
guard.
(21) Install the battery cables on the battery.
(22) Check the operation of the stop lamp switch
and adjust if necessary.
JUNCTION BLOCK
REMOVE
(1) Using a brake pedal depressor, move and lock
the brake pedal to a position past its first 1 inch of
travel. This will prevent brake fluid from draining
out of the master cylinder when the brake tubes are
removed from the junction block.
(2) Raise vehicle on jackstands or centered on a
hoist. See Hoisting in the Lubrication And Mainte-
nance Group of this service manual.
CAUTION: Before removing the brake tubes from
the junction block, the junction block and the brake
tubes must be thoroughly cleaned. This is required
to prevent contamination from entering the brake
hudraulic system.
(3) Remove the 6 chassis brake tubes (Fig. 129)
from the junction block.
(4) Remove the bolt (Fig. 130) attaching the junc-
tion block mounting braket to the front suspension
cradle.
INSTALL
(1) Install the junction block and mounting bracket
(Fig. 130) on the front suspension cradle. Install the
attaching bolt and tighten to a torque of 28 N·m (250
in. lbs.).
(2) Install the 6 chassis brake tubes (Fig. 131) into
the inlet and outlet ports of the junction block.
