- With the engine off and key off, pump the service brake pedal until all
the reserve vacuum is exhausted from the brake booster. A definite change in pedal
feel will occur.
- Install the SA9304NE
brake
pedal effort gage or equivalent, onto the brake pedal.
- Hook the end of the tape measure over the top edge of the brake pedal
and measure the distance to the rim of the steering wheel.
- Apply the service brake pedal with 445 N (100 lb) force
and re-measure. The difference between the "at rest" pedal position and the "applied"
pedal position is the actual pedal travel and should not exceed 57.0 mm (2.25 in).
- If the pedal travel is greater than the specification, refer to
Brakes Complaint/Condition Chart
for possible causes.
