BRAKE FLUID LEVEL SWITCH

DESCRIPTION

The brake fluid level switch is located in the brake
fluid reservoir of the master cylinder (Fig. 4).

OPERATION

The purpose of the brake fluid level switch is to
provide the driver with an early warning that the
brake fluid level in the master cylinder fluid reser-
voir has dropped below a normal level. This may
indicate:
• Abnormal loss of brake fluid in the master cyl-
inder fluid reservoir resulting from a leak in the
hydraulic system.
• Brake shoe linings which have worn to a point
requiring replacement.
As the brake fluid drops below the minimum level,
the brake fluid level switch closes to complete the red
BRAKE warning indicator (lamp) circuit. This will
turn on the red BRAKE warning indicator. The mas-
ter cylinder fluid reservoir should be checked and
refilled to the Full mark with DOT 3 brake fluid. If
the brake fluid level has dropped below the add
line in the master cylinder fluid reservoir, the
entire brake hydraulic
checked for evidence of a leak.

REMOVAL

(1) Remove wiring harness connector from brake
fluid reservoir level switch (Fig. 4).
(2) Using fingers, compress the retaining tabs on
the opposite end of brake fluid level switch.
(3) With retaining tabs compressed, grasp the con-
nector end of brake fluid level switch and pull it out
of master cylinder brake fluid reservoir.

INSTALLATION

(1) Insert brake fluid level switch into left side of
brake fluid reservoir. Be sure switch is pushed in
until retaining tabs lock it to brake fluid reservoir.
(2) Connect vehicle wiring harness connector to
brake fluid level switch (Fig. 4).
