where the warning lamp fails to turn on when it
should, or remains on when it should not.
The warning lamp bulb is supplied a 12 volt igni-
tion feed anytime the ignition switch is on. The bulb
is then illuminated by completing the ground circuit
either through the park brake switch, the fluid level
sensor in the master cylinder reservoir, the ignition
switch in the crank position or the ABS CAB.
The Brake Fluid Level sensor is located in the
brake fluid reservoir of the master cylinder assembly
(Fig. 16). The purpose of the sensor is to provide the
driver with an early warning that brake fluid level in
master cylinder reservoir has dropped to below nor-
mal. This may indicate an abnormal loss of brake
fluid in the master cylinder fluid reservoir resulting
from a leak in the hydraulic system.
As the fluid drops below the minimum level, the
fluid level sensor closes the brake warning light cir-
cuit. This will turn on the red brake warning light.
At this time, master cylinder fluid reservoir should
be checked and filled to the full mark with DOT 3
brake fluid. If brake fluid level has dropped in
master cylinder fluid reservoir, the entire
brake hydraulic system should be checked for
evidence of a leak.

The stop lamp switch controls operation of the
right and left tail, stop and turn signal lamp and
CHMSL lamp, by supplying battery current to these
lamps.
The stop lamp switch controls the lamp operation
by opening and closing the electrical circuit to the
stop lamps.
REAR WHEEL HUB AND BEARING ASSEMBLY
All vehicles are equipped with permanently lubri-
cated and sealed for life rear wheel bearings. There
is no periodic lubrication or maintenance recom-
mended for these units. However, if servicing of a
rear wheel bearing is required, refer to procedures in
the diagnosis and testing section and the removal
