Brake Pedal Assy: Testing and Inspection
BRAKE PEDAL SUPPORT ASSEMBLYON-VEHICLE INSPECTION
1. INSPECT BRAKE PEDAL HEIGHT
a. Check the brake pedal height.
Pedal height from dash panel: 150.3 to 160.3 mm (5.917 to 6.311 inch)
NOTICE: Do not adjust the pedal height. Doing so by changing the push rod length will structurally change the pedal ratio.
2. CHECK AND ADJUST STOP LAMP SWITCH
a. Disconnect the stop lamp switch assembly connector from the stop lamp switch assembly.
b. Turn the stop lamp switch assembly counterclockwise and remove the stop lamp switch assembly.
c. Insert the stop lamp switch assembly until the body hits the cushion.
NOTICE: When inserting the stop lamp 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 lamp switch assembly.
NOTICE:
^ When inserting the stop lamp switch assembly, support the pedal from behind so that the pedal is not pushed in.
^ The turning torque for installing the stop lamp switch assembly.
Torque: 1.5 Nm (15 kgf-cm, 13 inch lbs.) or less
e. Connect the stop lamp switch connector to the stop lamp switch assembly.
f. Check the protrusion of the rod.
Protrusion of the rod: 0.5 to 2.5 mm (0.020 to 0.098 inch)
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.
Pedal free play: 1 to 6 mm (0.04 to 0.24 inch)
4. CHECK PEDAL RESERVE DISTANCE
a. Release the parking brake pedal. 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 lbs): More than 52 mm (2.0 inch)
If the distance is out of the specification, troubleshoot the brake system.
