Standard pedal height from asphalt sheet: 183.7 to 193.7 mm (7.232 to 7.626 inch)
If the pedal height is not as specified, adjust it.
2. ADJUST BRAKE PEDAL HEIGHT
a. Remove the scuff plate, cowl side trim, No. 1 lower panel, LH lower panel and No. 2 heater to register duct.

k. After installation, push in the brake pedal 5 to 15 mm (0.20 to 0.59 inch), check that stop light lights up.
l. After adjusting the pedal height, check the pedal free play
m. Install the thrust stopper, steering column, upper and lower column covers, combination switch, steering wheel, No. 2 and No. 3 steering wheel lower covers, and steering wheel pad.
n. Install the No. 2 heater to register duct, LH lower panel, No. 1 lower panel, cowl side trim and scuff plate.
3. CHECK BRAKE PEDAL FREE PLAY
a. Stop the engine and depress the brake pedal more than 40 times until there is no more pressure left in the booster.
b. Push in the pedal by hand until the second point of resistance begins to be felt, then measure the distance, as shown in the illustration.
Standard pedal free play: 1.0 to 6.0 mm (0.039 to 0.236 inch)
If the distance is not as specified, check the stop light switch clearance. If the distance is as specified, then troubleshoot the brake system.
Standard stop light switch clearance: 1.9 mm (0.075 inch)
HINT: The free play to the first point of resistance is due to the play between the clevis, pedal link and pin. It is 1.0 to 6.0 mm (0.039 to 0.236 inch) on the pedal.
4. CHECK BRAKE PEDAL RESERVE DISTANCE
a. Remove the floor carpet.
b. Release the parking brake.
c. With the engine running, depress the pedal and measure the pedal reserve distance, as shown in the illustration.
