MAINTENANCE
BRAKES
To reduce the possibility of severe injury
or death, always evaluate pedal travel
before operating a vehicle to verify some
braking function is present.
All driving brake tests must be done in a
safe location with regard for the safety of
all personnel.
NOTICE: Over time, a subtle loss of per-
formance may take place;
therefore, it is important to
establish the standard with a
new vehicle.
Service brakes in accordance with the Peri-
odic Service Schedule. The Periodic Brake
Performance Test should be performed reg-
ularly as an evaluation of braking system
performance; it is useful as a method of
identifying subtle loss of performance over
time.
After the vehicles has been put into service,
it is recommended that the brakes be
checked by performing the following test:
Periodic Brake Test
Determine the braking performance of the
vehicle by engaging the brake at a common
point on a flat, dry, clean paved surface
while traveling at maximum speed. Observe
the vehicle stopping location. If the vehicle
stops in a significantly greater distance than
normal or pulls to one side, it should be
tested again.
If the vehicle fails the second test, it should
immediately be removed from service. The
vehicle needs to be inspected by a qualified
mechanic and repairs performed before
vehicle is returned to service.
