Brake Pedal Assy: Testing and Inspection
CHECKING PEDAL HEIGHTThe push rod serves as the brake pedal stopper when the pedal is fully released. Brake pedal height adjustment should be performed as follows:
Adjust Brake Pedal
1. Measure the brake pedal height after making sure the pedal is fully returned by the pedal return spring.
Pedal height must be measured after starting the engine and receiving it several times.
Pedal Free Play: 6 - 10 mm (0.23 - 0.39 inch)
Pedal Free Play: 208 - 218 mm (8.19 - 8.58 inch)
NOTE: Pedal free play must be measured after turning off the engine and stepping on the brake pedal firmly five times or more.
2. If the measured value is not within the above range, adjust the brake pedal as follows:
a. Disconnect the stoplight switch connector.
b. Loosen the stoplight switch lock nut (1).
c. Rotate the stoplight switch so that is moves away from the brake pedal.
d. Loosen the lock nut on the push rod.
e. Adjust the brake pedal to the specified height by rotating the push rod in the appropriate direction.
f. Tighten the lock nut to the specified torque.
Torque: 20 Nm (15 ft. lbs.)
g. Adjust the stoplight switch to the specified clearance (between the switch housing and the brake pedal) by rotating the switch housing.
Clearance: 0 - 0.2 mm (0 - 0.008 inch)
NOTE: While adjusting the stoplight switch, make sure that the threaded part of the stoplight switch does not push the brake pedal.
h. Tighten the stoplight switch lock nut.
i. Connect the stoplight switch connector.
CHECKING PEDAL TRAVEL
1. Pedal height (3) must be measured after starting the engine and rowing it several times to apply vacuum to the vacuum booster fully.
NOTE: Pedal height (3) must be 100 mm (3.9 inch) or more when about 50 kg (110.25 lbs.) of stepping force is applied.
2. If the measured value is lower than the above range, air existing in the hydraulic system is suspected. Perform the bleeding procedure.
