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 loca-

tion with regard for the safety of all personnel.

Over time, a subtle loss of performance may take place; there-

fore, it is important to establish the standard with a new vehi-

cle.

The Periodic Brake Performance Test should be performed regu-

larly as an evaluation of braking system performance. It is useful

as a method of identifying subtle loss of performance over time.

Periodic Brake Test

The purpose of this test is to compare the braking performance

of the vehicle to the braking performance of new or ‘known to be good’ vehicles or to an established acceptable stop-

ping distance. Actual stopping distances will be influenced by weather conditions, terrain, road surface condition, actual

vehicle weight (accessories installed) and vehicle speed. No specific braking distance can be reliably specified. The

test is conducted by latching the park brake to eliminate different pedal pressures and to include the affects of linkage

mis-adjustment.
Establish the acceptable stopping distance by testing a new or ‘known to be good’ vehicle and recording the stopping

location or stopping distance. For fleet vehicles, several vehicles should be tested when new and the range of stopping

locations or distances recorded.

Over time, a subtle loss of performance may take place; therefore, it is important to establish the standard with a

new vehicle.

Drive the vehicle at maximum speed on a flat, dry, clean, paved surface. Quickly depress the brake pedal to latch the

parking brake at the line or marker in the test area and remove foot from pedal. The vehicle should stop aggressively.

The wheel brakes may or may not lock. Observe the vehicle stopping location or measure the vehicle stopping distance

from the point at which the brakes were latched. The vehicle should stop within the ‘normal’ range of stopping dis-

tances. If the vehicle stops more than 4 ft. (1.2 m) beyond the acceptable stopping distance or pulls to one side, the

vehicle has failed the test and should be tested again.
If the vehicle fails the second test, it should

immediately be removed from service. The vehicle must be inspected by

a qualified mechanic who should refer to the TROUBLESHOOTING section in the Technician’s Repair and Service

Manual.

SYSTEM TEST

At monthly intervals, test the controller by allowing the vehicle to roll down an incline with the accelerator pedal

released. Braking force should be felt at approximately 2 mph (3 kph) indicating that the system is functioning. If vehicle

speed continues to rise, apply the service brake and have vehicle inspected by a trained mechanic.
