(12) Install the instrument panel insert sub-assembly lower LH and instrument panel finish panel sub-assembly lower.
2. CHECK PEDAL FREE PLAY
(a) Stop the engine and depress the brake pedal several times until no vacuum remains in the booster.





(b) Press the pedal until resistance is felt. Measure the distance, as shown in the illustration.
Pedal free play:
1 to 6 mm (0.04 to 0.24 in.)
If incorrect, proceed to the following step.
(1) Check the stop lamp switch clearance.
Stop light switch clearance:
0.5 to 2.4 mm (0.020 to 0.095 in.)
If correct, the pedal free play is OK.
If incorrect, adjust the stop light switch clearance.
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 in the illustration.
Pedal reserve distance from asphalt sheet at 490 N (50 kgf, 110 lbf):
w/o VSC: More than 68.5 mm (2.7 in.)
w/ VSC: More than 78.0 mm (3.1 in.)
If incorrect, troubleshoot the brake system.
