With engine running and transmission in PARK or NEUTRAL, block wheels and
release parking brake.
Install the Brake Pedal Effort Gauge 021-00001 or equivalent and check
brake pedal travel as follows.
Hook a steel measuring tape to the brake pedal (2455)
. Measure and record the distance from the brake pedal
free height position to the reference point, which is at the six o'clock
position on the steering wheel rim. Refer to the illustration under Brake Pedal
Free Height Measurements, Step 2.
With the steel tape still hooked to the brake pedal
, depress the brake pedal
by pressing downward on the brake pedal effort gauge.
Apply a 111 N (25 lb) load to the center of the brake pedal
. Maintain the pedal load and measure the distance from
the brake pedal
to the fixed reference point on the steering wheel rim
parallel to the centerline of the steering column.
The difference between the brake pedal free height and the depressed pedal
measurement under a 111 N (25 lb) load should be 79mm (3.1-inch) maximum.
If the above Steps do not bring the brake travel within specification,
bleed the brake system.
