NOTE: Before proceeding with this procedure,
review SERVICE WARNINGS AND CAUTIONS at the
beginning of REMOVAL AND INSTALLATION in this
section.
REMOVAL
CAUTION: The vacuum in the power brake booster
must be pumped down before removing the master
cylinder to prevent the booster from sucking in any
contamination. This can be done by pumping the
brake pedal while the engine is not running until a
firm brake pedal is achieved.
(1) With the engine not running, pump the brake
pedal 4-5 strokes until the pedal feel is firm.
(2) Disconnect the negative (ground) cable from
the battery and isolate the cable.
(3) Disconnect the positive cable from the battery,
then remove the battery from the battery tray. There
is one nut securing the clamp on the backside of the
battery holding it in place.
(4) Remove the vehicle wiring harness connector
from brake fluid level switch in master cylinder
brake fluid reservoir (Fig. 44).(5) Disconnect the two brake tubes from the mas-
ter cylinder, and two brake tubes from the propor-
tioning valves (Fig. 45). Install plugs at all of the
open brake tube outlets on the master cylinder.

BRAKES TUBES AND HOSES
NOTE: Brake hoses for each brake are unique and
are not interchangeable.
Always use Mopartreplacement brake hoses to
ensure quality, correct length and superior fatigue
life. Care should be taken to make sure that the tube
and hose mating surfaces are clean and free from
nicks and burrs.
Use new copper seal washers on all connections
using banjo bolts and tighten all the fittings to their
specified torques.
Follow the procedures in the next three paragraphs
to reduce the potential for twisting the brake hose
during installation.
The flexible front hydraulic brake hose should
always be installed on the vehicle by first attaching
the banjo fitting to the disc brake caliper. Attach the
hose to the brake tubing before attaching it to the
front frame rail. Tighten all brake line fittings to the
specified torque.
On vehicles equipped with rear drum brakes,
loosely install the rear brake hose to the wheel cylin-
der first, then bolt the intermediate routing bracket
to the strut. Next, loosely install the hose to the steel
tube coming from the master cylinder. Attach the
hose bracket to the body. Finally, tighten the tube
nuts at each end of the brake hose.
On vehicles equipped with rear disc brakes, attach
the brake hose banjo fitting to the caliper first, then
loosely install the hose to the steel tube coming from
the master cylinder. Next, attach the brake hose
bracket to the body. Finally, tighten the tube nut at
the each of the end of the brake hose connecting to
the steel tube coming from the master cylinder.Only double wall 4.75 mm (3/16 in.) steel brake
line tubing with Nygal coating should be used for
replacement along with its special tube nuts. Care
must be taken when replacing brake tubing; to be
sure, use the proper bending and flaring tools, and
procedures to avoid kinking. Do not route the tubes
against sharp edges, moving components, or into hot
areas. All tubes should be properly attached with the
recommended retaining clips.
