EXCESSIVE PEDAL TRAVEL INSPECTION
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 30 kg (66
lbs) load, measure brake pedal to wall (dash panel silencer)
clearance "a".
If clearance "a" is less than specification, the most possible
cause is either rear brake shoes are worn out beyond limit or
air is in lines.
Should clearance "a" remain less than specification even
after replacement of brake shoes and bleeding of system,
other possible but infrequent cause is malfunction of rear
brake shoe adjusters or booster push rod length out of
adjustment.
– Bleed brake system. Refer to "AIR BLEEDING OF BRAKE
SYSTEM".
– Remove brake drums for adjuster inspection. (Refer to
"REAR BRAKE".) If defective, correct or replace.
Clearance "a" between brake pedal and dash panel
silencer
LH steering vehicle : over 135 mm (5.32 in.)
RH steering vehicle : over 140 mm (5.52 in.)
FRONT BRAKE PAD INSPECTION
Inspect pad linings (1) periodically according to maintenance
schedule whenever wheels are removed (for tire rotation or other
reason). Take a look through each end (or hole) of caliper and
check lining thickness of outside and inside pads.
If lining is worn and its thickness ("a" in figure) is less than limit, all
pads must be replaced at the same time.
Front brake pad thickness "a" (lining thickness)
Standard : 10 mm (0.40 in.)
Limit : 2 mm (0.08 in.)
