BRAKE PEDAL PLAY CHECK
Pedal play should be within specification below.
If out of specification, check stop 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 “f”: 1 – 8 mm (0.04 – 0.31 in.)
MASTER CYLINDER CHECK
Check master cylinder casting for crack or fluid leak. Leaks are in-
dicated only if there is at least a drop of fluid. A damp condition is
not normal.
REAR DRUM BRAKE SHOE ADJUSTMENT
Rear brake has self-adjusting mechanism but it does require ad-
justment for proper drum to shoe clearance when brake shoe has
been replaced or brake drum has been removed for some other
service.
Adjustment is automatically accomplished by depressing brake
pedal about 30 times with approximately 30kg (66 lbs) load after
all parts are installed.
Then check brake drum for dragging and brake system for proper
performance. After lowering vehicle from hoist, brake test should
be performed.
PARKING BRAKE CHECK AND ADJUST-
MENT
CHECK
Hold center of parking brake lever grip and pull it up with 20 kg (44
lbs) force.
With parking brake lever pulled up as above, count ratchet notches
in “A” as shown in figure.
There should be 8 to 11 notches.
Also, check if both right and left rear wheels are locked firmly. To
count number of notches easily, listen to click sounds that ratchet
makes while pulling parking brake level without pressing its button.
One click sound corresponds to one notch.
