ACCELERATOR AND BRAKE PEDAL GROUP
Pedal Group Adjustment – Gasoline Vehicle, Continued:
3. Adjust brake pedal free play. See following NOTE.
NOTE: Brake pedal free play is the distance the brake pedal can be pressed before the brake actuator
arm (at the brake cluster) moves.
3.1. Measuring perpendicular from the floorboard to the back of the brake pedal, press the brake pedal
and measure the distance that the pedal moves before all of the slack is taken out of the brake
cables (Figure 5-11, Page 5-11).
3.2. Tighten the nut (2) on the equalizer rod (1) so that the brake pedal free play is 1/4 to 1/2 inch (6.3
to 12.7 mm) (Figure 5-12, Page 5-12).
3.3. Tighten the jam nut (3) while holding the adjustment nut (2) in the correct position.

4. Adjust park brake ratchet/pawl gap and pawl engagement.
4.1. Inspect the park brake pawl and ratchet for excessive wear, grooves, cracks or chips. If either the
pawl or ratchet is damaged, both must be replaced.
4.2. Adjust retaining nut (7) on spring support rod until there is a 0.060 inch (1.5 mm) gap between the
pawl and the tips of the ratchet teeth. Use a feeler gauge to verify the gap (Figure 5-13,
Page 5-13). The gap should be consistent through range of pawl movement. If the gap is not con-
sistent, loosen the four bolts (6) securing the accelerator pivot rod supports and adjust the supports.
If the gap becomes smaller as the park brake pedal is pressed, move the pivot rod supports slightly
rearward until the gap is consistent. If the gap becomes larger as the park brake pedal is pressed,
move the pivot rod supports slightly forward until gap is consistent. See following NOTE.
NOTE: The accelerator rod must also be checked if the ratchet/pawl gap is adjusted. See step 6 of Pedal
Group Adjustment – Gasoline Vehicle on page 5-14.
The accelerator rod must be disconnected before proceeding to step 4.3.
