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.
Over time, a subtle loss of performance may take place; therefore, it is important to establish the standard with a new
vehicle.
The Periodic Brake Performance Test should be performed regularly as an evaluation of braking system perfor-
mance. It is useful as a method of identifying subtle loss of performance over time.
Periodic Brake Test For Mechanical Brakes
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 stopping distance.
Actual stopping distances will be influenced by weather condi-
tions, 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 latch-
ing 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 fleets of vehicles, several vehicles should
be tested when new and the range of stopping locations or dis-
tances 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 distances. 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 Ser-
vice Manual.
