BRAKE: BRAKE PEDAL: ADJUSTMENT

ADJUSTMENT

1. CHECK AND ADJUST BRAKE PEDAL HEIGHT





(a) Check the brake pedal height.
Pedal height from dash panel:
129.9 to 139.9 mm (5.114 to 5.508 in.)
(b) Adjust the brake pedal height.
(1) Disconnect the connector from the stop light switch assembly.
(2) Remove the stop light switch.
(3) Loosen the push rod clevis lock nut.
(4) Adjust the pedal height by turning the pedal push rod.
Pedal height from the dash panel:
129.9 to 139.9 mm (5.114 to 5.508 in.)
(5) Tighten the clevis lock nut.
Torque: 26 Nm (265 kgf-cm, 19ft-lbf)




(6) Insert the switch into the adjuster until the switch body touches the pedal.
NOTICE: Do not depress the pedal.
(7) Rotate the switch a quarter turn clockwise.
Torque: 1.5 Nm (15 kgf-cm, 13in-lbf)
NOTICE: Do not depress the pedal.




(8) Check the switch clearance.
Standard stop light switch clearance:
1.5 to 2.5 mm (0.059 to 0.098 in.)
(9) Connect the connector to the stop light switch assembly.
2. ADJUST BRAKE PEDAL STROKE SENSOR ASSEMBLY
(a) Connect Techstream to the DLC3 with the power switch off.





(b) Loosen the 2 bolts.
(c) Turn the power switch on (IG).
(d) Turn on Techstream.





(e) Reading the stroke sensor 1 value shown on the Techstream screen, turn the stroke sensor slowly to the right and left to adjust it to the standard voltage.
Standard voltage:
0.8 to 1.2 V
(f) Tighten the 2 bolts.
Torque: 8.5 Nm (87 kgf-cm, 75in-lbf)
NOTICE: Do not depress the brake pedal after turning the power switch on (IG).

(g) Perform linear valve offset learning. Initialization
3. CHECK PEDAL FREE PLAY





(a) Depress the pedal until a slight resistance is felt. Measure the distance as shown in the illustration.
Pedal free play:
1 to 2 mm (0.039 to 0.079 in.)
(1) If the pedal free play is 1.0 mm (0.039 in.) or less, check the protrusion of the stop light switch assembly shaft.
Protrusion of the stop light switch assembly shaft:
0.5 to 2.4 mm (0.020 to 0.095 in.)
- Adjust if the protrusion is off the specified value.
- If the protrusion is within the specified value, it is normal though brake pedal free play is 1.0 mm (0.039 in.) or less.

4. CHECK PEDAL RESERVE DISTANCE





(a) Release the parking brake pedal.
(b) With the engine running, depress the pedal and measure the pedal reserve distance as shown in the illustration.
Pedal reserve distance from the dash panel at 490 N (50 kgf, 110 lbf):
More than 80 mm (3.15 in.)
