CHECK AND ADJUSTMENT
BRAKE PEDAL FREE HEIGHT ADJUSTMENT
Check brake pedal free height (distance).
If it is not within specification, check and adjust following item 1)
and 2).
Brake pedal free distance “a”
from dash panel:209–215 mm (8.23–8.46 in.)
LHD vehicle . .
201–207 mm (7.90–8.15 in.) RHD vehicle . .
1) Check measurement between booster mounting surface and
center of clevis pin hole. When booster push rod clevis has
been reinstalled, it is important that the measurement is ad-
justed.
Length “b”: 99.5 – 100.5 mm (3.92 – 3.96 in.)
Tightening Torque
(a): 25 N·m (2.5 kg-m, 18.0 lb-ft)
2) Check stop light switch position. Adjust it if it is out of specifica-
tion.
1. Push rod clevis
STOP LIGHT SWITCH ADJUSTMENT
Adjustment should be made as follows when installing switch. Pull
up brake pedal toward you and while holding it there, adjust switch
position so that clearance between end of thread and brake pedal
is specified. Then tighten lock nut to specified torque.
Clearance “a”: 1.5 – 2.0 mm (0.06 – 0.08 in.)
Tightening Torque
(a): 7.5 N·m (0.75 kg-m, 5.5 lb-ft)
EXCESSIVE PEDAL TRAVEL CHECK
1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 30kg (66 lbs)
load, measure brake pedal to wall clearance “a”.
Clearance “a”: Over 165 mm (6.50 in.) LHD vehicle . .
Over 145 mm (3.71 in.) RHD vehicle . .
4) 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 pos-
sible but infrequent causes are malfunction or misadjusted of
rear brake shoe adjusters or booster push rod length out of ad-
justment.
Refer to BLEEDING BRAKES for bleeding brake system.
Remove brake drums for adjuster inspection, (refer to
BRAKE DRUM INSPECTION.) If defective, correct or re-
place.
