BRAKE FLUID CONTAMINATION
Indications of fluid contamination are swollen or deteri-
orated rubber parts.
Swollen rubber parts indicate the presence of
petroleum in the brake fluid.To test for contamination, put a small amount of
drained brake fluid in clear glass jar. If fluid sepa-
rates into layers, there is mineral oil or other fluid
contamination of the brake fluid.
If brake fluid is contaminated, drain and thor-
oughly flush system. Replace master cylinder, propor-
tioning valve, caliper seals, wheel cylinder seals,
Antilock Brakes hydraulic unit and all hydraulic
fluid hoses.

traction control switch on and off. The traction con-
trol switch used on this vehicle is a momentary con-
tact type switch. The test procedure for the traction
control light is performed as follows: Press the trac-
tion control switch once and the ªTrac Offº lamp will
illuminate. With the ªTrac Offº lamp illuminated,
press the traction control switch again and the ªTrac
Offº lamp will turn off.
If the traction control lamp does not function as
described in the test above, diagnosis of the traction
control switch, lamp, wiring and other related compo-
nents of the traction control system is required.

brake pedal to adequately stop vehicle.
(19) Road test vehicle to ensure proper operation
of the brake system.MASTER CYLINDER
CAUTION: Different types of master cylinders are
used on this vehicle. Vehicles equipped with trac-
tion control use a center port master cylinder. Vehi-
cles not equipped with traction control use a
compensating port master cylinder. Be sure to ver-
ify if the vehicle is equipped with traction control
and that the correct replacement master cylinder is
used. Also, vehicles that are equipped with four
wheel disc brakes have a master with a different
size piston bore than the other master cylinders. If
a new master cylinder is being installed, be sure
the correct master cylinder is used for the type of
brake system the vehicle is equipped with.
REMOVE
CAUTION: Vacuum in the power brake booster
must be pumped down (removed) before removing
master cylinder from power brake booster. This is
necessary 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 the brake
pedal until a firm pedal is achieved (4-5 strokes).
CAUTION: Before removing the master cylinder
filler tube from the brake fluid reservoir, the filler
tube, brake fluid reservoir and master cylinder must
be thoroughly cleaned. This must be done to pre-
vent dirt particles from falling into the brake fluid
reservoir and entering the brakes hydraulic system.
