Parts Replacement vs. Repair

Some maintenance or repair tasks can take consider-

able labor to do correctly. Assessment of the condition of

worn components is critical to the operation of the brake

system. In some cases, component replacement may be

more cost effective than the removal, cleaning, inspec-

tion and reassembly of the component(s).

Adjusting Brake Pedal Free Travel

Brake pedal free travel MUST be checked and adjusted

any time that the brake system is serviced or when

parts are replaced.
Brake pedal free travel is the distance the pedal travels

from rest to the point at which the brake cables start to

move the brake levers. This should not be confused with

the light resistance that is felt as the brake pedal is

depressed enough to remove slack from the compensa-

tor and cables. Correct adjustment of free travel is

essential to proper brake function. Too much pedal free

travel will limit braking capability. Too little pedal free

travel may cause the brakes to drag (not fully released).

Either condition can prevent the brakes from adjusting

properly.

This procedure is intended to adjust the
brakes and seat brake system components.
The brake system may not be effective for the
first few applications of the brake pedal.

Pre-adjust service brake pedal free travel to the correct

setting by loosening the jam nut and adjusting the spher-

ical nut (Ref Fig. 20). Tighten the jam nut to 10 - 11 ft.

lbs. (14 - 15 Nm).
The correct brake pedal free travel should be set to 7/8"

- 1 1/8" (2.2 - 2.9 cm).
Press the brake pedal aggressively 4 - 6 times to estab-

lish known free travel.

All brake tests must be done in a safe location
with regard for the safety of all personnel.

In a safe location free from people and vehicles, drive

the vehicle at reduced speed and apply the brakes
