5-10 BRAKES

BRAKE PEDAL PLAY CHECK

Pedal play should be within specification. If out of specification,
check brake light switch for proper installation position and adjust
if necessary.
Also check pedal shaft bolt and master cylinder pin installation for
looseness and replace if defective.
Pedal play "d": 1 – 8 mm (0.04 – 0.32 in.)

BRAKE FLUID LEVEL CHECK

Be sure to use particular brake fluid either as indicated on reservoir
cap of that vehicle or recommended in owner's manual which
comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked on reser-
voir.
When warning light lights sometimes during driving, replenish fluid
to MAX line.
When fluid decreases quickly, inspect brake system for leakage.
Correct leaky points and then refill to specified level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has been
used for mineral oil or a container which is wet from water.
Mineral oil will cause swelling and distortion of rubber parts
in hydraulic brake system and water mixed into brake fluid
will lower fluid boiling point. Keep all fluid containers
capped to prevent contamination.

BRAKE HOSE AND PIPE CHECK

The brake hose assembly should be checked for road hazard dam-
age, for cracks and chafing of the outer cover, for leaks and blisters.
A light and mirror may be needed for an adequate inspection. If any
of the above conditions are observed on the brake hose, it is neces-
sary to replace it.
Inspect the pipe for damage, cracks, dents and corrosion. If any de-
fect is found, replace it.

MASTER CYLINDER CHECK

Check for a cracked master cylinder casting or brake fluid around
the master cylinder. Leaks are indicated only if there is at least a
drop of fluid. A damp condition is not abnormal.
