SERVICE BRAKE (FULL AIR BRAKE) BR02–83
(3) Combination Friction Linings
! CAUTION
When you install combination friction linings, you must install the pri-
mary lining on the primary brake shoe. If you install combination fric-
tion linings incorrectly, damage to components will result. Carefully
follow instructions included with the replacement linings.
You can combine brake linings, which means that the linings you
install on the primary shoe will have a different friction rating than the
linings you install on the secondary shoe.
However, you must install the primary lining on the primary shoe.
Carefully follow the instructions included with the replacement combi-
nation linings.
(4) Primary Shoe Locations
The first shoe past the camshaft in the direction of wheel rotation is
the primary shoe. The primary shoe can be either at the top or bottom
position, depending on the location of the camshaft.
If the camshaft is behind the axle, the top shoe is the primary shoe.
If the cam is in front of the axle, the top shoe is the primary shoe.
9. BEFORE YOU RETURN THE VEHICLE TO SERVICE
(1) Check the complete air system for worn hoses and connectors. With
air pressure at 100 psi (689 kPa), brakes released and engine off, loss
of tractor air pressure must not exceed two psi a minute. Total tractor
and trailer loss must not exceed three psi per minute.
(2) Check to see that the air compressor drive belt is tight. Air system
pressure must rise to approximately 100 psi (689 kPa) in two minutes.
(3) The governor must be checked and set to the specifications supplied
by the vehicle manufacturer.
(4) Both the tractor and trailer air systems must match the specifications
supplied by the vehicle manufacturer.
