Repair and Service Manual
Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes,
To assure correct braking performance, all peri-
odic maintenance, inspections and procedures
must be performed as indicated in the Periodic Service Sched-
ule in Section ‘A’ of this manual. It is most important that a
Daily Brake Performance Test be performed and the entire
brake system be serviced in accordance with the Periodic
Service Schedule.
GENERAL
The brake system is mechanical and consists of actuat-
ing linkages and manually adjusted wheel brake assem-
blies. The actuating linkages require periodic adjustment
to compensate for the normal wear of system compo-
nents. Replacement of any linkage components will also
require a linkage adjustment.
The wheel brake units are manually adjusted which
requires periodic adjustment to compensate for brake
shoe wear. The brake
does require routine inspection
and lubrication of the backing plate and adjuster mecha-
nism (See Periodic Service Schedule in Section ‘A’ of this
manual).
If any brake system component is replaced,
the entire brake system must be adjusted.
To determine the adequacy of the vehicle brake system,
a brake performance test should be performed daily.
DAILY BRAKE PERFORMANCE TEST
All brake tests must
b e d o n e i n a s a f e
location with regard
for the safety of all personnel.
General
Since weather conditions and terrain frequently vary, no
specific braking distance can be specified. The test is
intended to compare similar vehicles by applying the
parking brake (to eliminate different pedal pressures) at a
common point to determine if any vehicle shows signifi-
cantly different braking characteristics from other vehi-
cles being tested.
Since loss of braking performance can deteriorate over a
prolonged period, brake performance characteristics
should also be compared to the performance of a new
vehicle.
Test Method
On a dry paved surface that is free of gravel, sand, etc.,
approach a marker at full speed (Ref Fig. 1 on page J-1).
Engage the service brake at the marker and observe the
stopping distance of the vehicle. Any vehicle that stops in
a significantly greater distance than an acceptable vehi-
cle should be tested again. If it again fails to stop in an
acceptable distance, it should be immediately removed
from service and inspected by a qualified mechanic.
