RECOMMENDED BRAKE FLUID
The only brake fluid recommended for Jeep vehi-
cles with standard or antilock brakes, is Mopar brake
fluid, or an equivalent fluid meeting SAE J1703 and
DOT 3 standards.
Use new brake fluid only to top off the master
cylinder or refill the system. Never use re-
claimed fluid, fluid not meeting the SAE/DOT
standards or fluid from an unsealed container.
Do not use fluid from any container that has
been left open for any length of time. Fluid in
open containers can absorb moisture.
BRAKE FLUID LEVEL
Always clean the master cylinder and cover before
checking fluid level. If not cleaned, dirt from the
cover could enter the fluid. Also check the cover seal
and replace it if torn or distorted.
Correct fluid level is to within 6 mm (1/4 in.) of the
reservoir rim, or to the fill mark on models with a
plastic reservoir. Refer to the Antilock Brake section
for fluid levels on models equipped with ABS brakes.
BRAKE FLUID CONTAMINATION
Oil in the fluid will cause brake system rubber
seals to soften and swell. The seals may also become
porous and begin to deteriorate.
If fluid contamination is suspected, drain off a sam-
ple from the master cylinder. A suction gun or simi-
lar device can be used for this purpose.
Empty the drained fluid into a glass container.
Contaminants in the fluid will cause the fluid to sep-
arate into distinct layers. If contamination has oc-
curred, the system rubber seals, hoses and cups must
be replaced and the system thoroughly flushed with
clean brake fluid.
BRAKE BLEEDINGÐXJ/YJ WITH STANDARD
BRAKES
Use Mopar DOT 3 brake fluid, or an equivalent
meeting SAE/DOT standards J1703-F and DOT 3, to
fill and bleed the system.
On standard brake models, bleeding can be per-
formed either manually or with pressure equipment.
However, if pressure equipment is used, it will be
necessary to hold the front brake metering valveopen in order to bleed the front brakes. The valve
can be held open with a tension clip tool or by hand.
It will also be necessary that a suitable size pressure
tank hose adapter be available for use on the master
cylinder.
MANUAL BLEEDING PROCEDURE
(1) If master cylinder has been overhauled or a
new cylinder will be installed, bleed cylinder on
bench before installation. This shortens time needed
to bleed system and ensures proper cylinder opera-
tion.
(2) Wipe master cylinder reservoir and cap clean
with shop towels.
(3) Remove cover and fill master cylinder reservoir
with Mopar, or equivalent DOT 3 brake fluid.
(4) Open all caliper and wheel cylinder bleed
screws.
(5) Close bleed screws after fluid begins flowing
from each bleed screw.
(6) Top off master cylinder reservoir again.
(7) Use following bleed sequence:
²master cylinder
²right rear
²left rear
²right front
²left front
(8) Observe following brake bleeding precautions:
²Do not pump brake pedal at any time while bleed-
ing. Air in system will be compressed into small bub-
bles that are distributed throughout hydraulic
system. This will make a second and third bleeding
operation necessary.
²Bleed only one wheel brake unit at a time and use
a bleed hose to bleed each wheel brake unit (Fig. 7).
²Attach one end of bleed hose to bleed screw and in-
sert opposite end in glass container partially filled
with brake fluid (Fig. 7). Glass container makes it
easier to see air bubbles as they exit the bleed hose.
²Be sure end of bleed hose is immersed in fluid. Im-
mersing hose end in fluid prevents air from being
drawn back into cylinder and brakeline.
(9) Bleed master cylinder first. Have helper oper-
ate brake pedal while bleeding each master cylinder
fluid outlet line.
JBRAKES 5 - 13

CAUTION: Do not allow the master cylinder to run
out of fluid when bleeding the brakes. An empty
cylinder will allow additional air to be drawn into
the system. Check the cylinder fluid level frequently
and add fluid as needed.
(10) Bleed each wheel brake unit as follows:
(a) Open caliper or wheel cylinder bleed fitting
1/2 to 3/4 turn.
(b) Have helper press and hold brake pedal to
floor.Do not pump brake pedal while bleeding.
Air in system will be compressed into small
bubbles that are distributed throughout hy-
draulic system. This will make a second and
third bleeding operation necessary.
(c) Tighten bleed fitting and have helper release
brake pedal. Continue bleeding operation until
fluid entering bleed container is clear and free of
bubbles.
(d) Repeat bleeding operation at remaining
wheel brake units.
(e) Discard fluid bled into glass container. It
should not be reused.
(11) Check and adjust master cylinder fluid level.
(12) Verify proper brake operation before moving
vehicle.
PRESSURE BLEEDING
The front brake metering valve is located in the
forward end of the combination valve. The valve
stem is accessible from the same end of the valve.
The stem must be either pressed inward, or held out-
ward slightly in order to bleed the front brakes.
(1) Fill bleeder tank if necessary.
(2) Purge air from bleeder tank and lines before
proceeding.(3) Wipe master cylinder cover clean.
(4) Remove master cylinder cover and install pres-
sure hose adapter in place of cover. A suitable
adapter will usually be available from tank manufac-
turer.
(5) Connect bleeder tank pressure hose to adapter.
(6) Bleed master cylinder first. Then bleed rear
brakes as described in manual bleeding procedure.
(7) Bleed front brakes as described in manual
bleeding procedure. Have helper hold metering valve
open by pressing valve stem inward slightly. Amount
of valve stem movement needed to hold valve open is
quite modest. Do not use excessive force.
(8) Remove pressure bleeding equipment and top
off master cylinder reservoir.
BRAKE BLEEDINGÐXJ/YJ WITH ABS BRAKES
A different bleeding method is required for the
ABS system. It is basically a three step process
consisting of: A conventional manual brake
bleed. A second bleed using the DRB II, fol-
lowed by a repeat of the conventional manual
bleed procedure. Recommended ABS bleeding
procedure is as follows:
(1) Clean master cylinder reservoir caps and reser-
voir exterior. Dirt, foreign material on the caps and
reservoir must not be allowed to enter reservoir.
(2) Fill reservoir with Mopar brake fluid, or equiv-
alent quality fluid meeting SAE 1703 and DOT 3
standards.
(3) Recommended bleeding sequence is:
²master cylinder
²HCU valve body (at fluid lines)
²right rear wheel
²left rear wheel
²right front wheel
²left front wheel.
(4) Attach bleed hose to caliper or wheel cylinder
bleed fitting. Immerse end of bleed hose in glass con-
tainer partially filled with brake fluid. Be sure hose
end is submerged in fluid (Fig. 7).
(5) Bleed each wheel brake unit as follows:
(a) Have helper apply and hold brake pedal.
(b) Open bleed screw 1/2 turn. Close bleed screw
when brake pedal contacts floorpan.Do not pump
brake pedal at any time while bleeding. This
compresses air into small bubbles which are
distributed throughout system. Additional
bleeding operations will then be necessary to
remove all trapped air from the system.
(c) Repeat bleeding operation 5-7 more times at
each rear wheel brake unit.
(d) Continue bleeding until fluid entering glass
container is free of air bubbles. Check reservoir
fluid level frequently and add fluid if necessary.
(e) Repeat bleeding procedures at front wheels.

5 - 14 BRAKESJ

CAUTION: Do not allow the master cylinder reser-
voir to run dry while bleeding the brakes. Running
dry will allow air to re-enter the system making a
second bleeding operation necessary.
(6) Perform ``Bleed Brake'' procedure with DRB II
scan tool. Procedure is described in DRB II software
information and diagnostic manual.
(a) Connect DRB II scan tool to diagnostic con-
nector.
(b) Run Bleed Brake procedure as described in
tester manual.
(7) Repeat conventional bleeding procedure out-
lined in steps (1) through (8).
(8) Top off master cylinder fluid level if necessary.
(9) Verify proper brake operation.
BRAKELINES AND HOSES
Metal brakelines and rubber brake hoses should be
inspected periodically and replaced if damaged.
Rubber brake hoses should be replaced if cut,
cracked, swollen, or leaking. Rubber hoses must be
replaced. They are not repairable parts.
When installing new, or original brakelines andhoses, lubricate the fitting threads with brake fluid
before connection.
The steel brakelines should be checked every time
the vehicle is in for normal maintainence. This is im-
portant on high mileage vehicles. It is even more im-
portant when a vehicle is operated in areas where
salt is used regularly on the road surface during win-
ter.
Heavily rusted/corroded brake rotors, drums, sup-
port plates, and brakelines should be cleaned and
carefully inspected. Heavy rust buildup can hide se-
vere damge to a component. Severely rusted parts
should be replaced if you are unsure about their con-
dition.
COMBINATION VALVE
The combination valve is not a serviceable part.
The valve must be replaced if a malfunction occurs.
BRAKELINE CHARTS
Brakeline charts are provided in illustration Fig-
ures 1 through 8. The illustrations show typical
brakeline routing, hose connections and component
position.
