Fig. 34 Typical Brake Performance Test

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 per-
formed regularly (Ref. Fig. 21 on page 14) as an evalua-
tion of braking system performance or if there is a
decrease in braking effectiveness. 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 perfor-
mance 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 conditions, terrain, road
surface condition, actual vehicle weight (accessories
installed) and vehicle speed. No specific braking dis-
tance can be reliably specified. The test is conducted by
latching the parking 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 vehi-
cles, 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 (Ref. Fig. 34 on page 20). 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 accept-
able 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 TROU-
BLESHOOTING section in the Technicain's Repair and
Service Manual.
Hydraulic Front Disc Brakes
For vehicles equipped with hydraulic front disc brakes,
check master cylinder fluid per PERIODIC SERVICE
SCHEDULE or if there is a decrease in braking effective-
ness. Inspect components for damage or wear. It is
unlikely that fluid will need to be added unless there is a
leak in the system. Raise the front of the vehicle (See
raising the vehicle). Remove passenger side wheel/tire.
Carefully wipe off dirt and debris from master cylinder
and cap before opening. Remove the cap. Using a
mechanics mirror, check to see that fluid is no more than
