1. CHECK AND ADJUST BRAKE PEDAL HEIGHT
(a) Inspect brake pedal height.
Pedal height from dash panel:
RHD: 142.5 to 152.5 mm (5.610 to 6.004 in.)
LHD:
M/T: 148.1 to 158.1 mm (5.831 to 6.224 in.)
A/T: 149.9 to 159.9 mm (5.902 to 6.295 in.)
(b) Adjust brake pedal height.
(1) Remove the instrument finish panel lower.
(2) Disconnect the connector from the stop lamp switch
assy.
(3) Turn the stop lamp switch assy counterclokwise and
remove the stop lamp switch assy.
(4) Loosen the brake master cylinder push rod clevis
lock nut.

(h) Check the protrusion of the rod.
Protrusion of the rod: 0.5 to 2.6 mm (0.020 to 0.102 in.)
(i) Install the clevis pin and clip.
(j) After adjusting the pedal height, check the pedal free
play.
2. CHECK PEDAL FREE PLAY
(a) Stop the engine and depress the brake pedal several
times until there is no more vacuum left in the booster.
(b) Push in the pedal until the beginning of the resistance is
felt. Measure the distance, as shown.
Pedal free play: 1 to 6 mm (0.04 to 0.24 in.)
3. CHECK PEDAL RESERVE DISTANCE
(a) Release the parking brake lever.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance from asphalt sheet at 490 N
(50 kgf, 110.2 lbf): More than 50 mm (1.97 in.)
If the distance is out of the specification , troubleshoot the brake
system.
