b. Press the pedal until resistance is felt. Measure the distance as shown in the illustration.
Pedal freeplay: 1.0 to 6.0 mm (0.039 to 0.236 inch)
If incorrect, proceed to the following step:
1. Check the stop lamp switch clearance.
Stop lamp switch clearance: 1.5 to 2.5 mm (0.059 to 0.098 inch)
If the clearance is OK, troubleshoot the brake system.
If incorrect, adjust the stop lamp switch clearance.
3. CHECK PEDAL RESERVE DISTANCE
a. Release the parking brake pedal.
b. With engine running, depress the pedal and measure the pedal reserve distance, as shown in the illustration.
