BRAKE PEDAL:
MAINTENANCE Every 3 months or quarterly:
1. Lubricate fulcrum and roller pin with oil.
2. Free pedal travel should be checked as follows:
Check to be certain plunger is in contact with spring
seat. The stop button should be adjusted so that the
roller and plunger just contact.
3. Apply oil or light grease between plunger and valve
body. Do not overoil.
4. Clean exhaust check depending on type of service.
Every 12 months or annually:
1. Disassemble, clean parts with mineral spirits. Re-
place all rubber parts or any part worn or damaged.
Check for proper operation before placing vehicle
in service.
NOTE:
All rubber components in the treadle valve should be
replaced yearly.
IMPORTANT!
An increase in stopping distance or a low pressure
warning light indicated a malfunction in the brake sys-
tem, and although the vehicle brake system may con-
tinue to function, the vehicle should not be operated
until the necessary repairs have been made and both
braking circuits are operating normally.
LEAKAGE CHECK
1. Make and hold full brake application.
2. Coat the exhaust port and body of the brake valve
with soap solution.
3. Leakage is not to exceed a 1” bubble in 3 seconds
in both the applied and released position.
If the brake does not function as described above or
leakage is excessive, it is recommended that it be re-
placed with a new or remanufactured unit, or repaired
with genuine Bendix parts available at Bendix outlets.
