Brake Pedal Assy: Adjustments
BRAKE: BRAKE PEDAL: ADJUSTMENT
ADJUSTMENT
1. CHECK BRAKE PEDAL HEIGHT
(a) Check the brake pedal height.
Pedal height from dash panel:
181.6 to 191.6 mm (7.15 to 7.54 in.)
NOTE: Do not adjust the pedal height. Doing so by changing the push rod length will structurally change the pedal ratio.
If the pedal height is incorrect, adjust the rod operating adapter length.
(b) Adjust the rod operating adapter length.
(1) Remove the clip and clevis pin.
(2) Loosen the clevis lock nut.
(3) Adjust the rod operating adapter length by turning the pedal push rod clevis.
Rod operating adapter length "A":
220.2 to 221.2 mm (8.67 to 8.71 in.)
(4) Tighten the clevis lock nut.
Torque: 26 Nm (265 kgf-cm, 19 ft-lbf)
(5) Install the clip and clevis pin.
If the pedal height is incorrect even if the rod operating adapter is adjusted, check that there is no damage in brake pedal, brake pedal lever, brake pedal bracket and dash panel.
- Even if there is damage, there is no problem if the reserve distance is within the standard value.
- If necessary, replace them.
2. CHECK AND ADJUST STOP LIGHT SWITCH ASSEMBLY
HINT: If the pedal height is incorrect, check and adjust the stop light switch clearance.
(a) Disconnect the stop light switch assembly connector from the stop light switch assembly.
(b) Turn the stop light switch assembly counterclockwise and remove the stop light switch assembly.
(c) Insert the stop light switch assembly until the body hits the cushion.
NOTE: When inserting the stop light switch assembly, support the pedal from behind so that the pedal is not pushed in.
(d) Make a quarter turn clockwise to install the stop light switch assembly.
NOTE: The turning torque for installing the stop light switch should be 1.5 N*m (15 kgf*cm, 13 in.*lbf) or less.
HINT: Due to the inverse screw structure, if the stop light switch assembly is turned clockwise, the stop light switch assembly moves in the direction to be pulled out.
(e) Connect the stop light switch connector to the stop light switch assembly.
(f) Check the protrusion of the rod.
Protrusion of the rod:
1.5 to 2.5 mm (0.0591 to 0.0984 in.)
(g) Install the clevis pin and clip.
(h) After adjusting the pedal height, check the pedal free play.
3. 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 in the illustration.
Pedal free play:
1 to 6 mm (0.0394 to 0.236 in.)
4. CHECK PEDAL RESERVE DISTANCE
(a) Release the parking brake pedal.
With engine running, depress the pedal and measure the pedal reserve distance, as shown in the illustration.
Pedal reserve distance from asphalt sheet at 490 N (50 kgf, 110.2 lbf):
More than 55 mm (2.17 in.)
If incorrect, troubleshoot the brake system.
