● Using a ratchet with a 9/16” socket, turn the adjustment bolt (1) clockwise
until the brake linings touch the drum. Then, loosen ½ turn counterclockwise
to set clearance. Repeat for each slack adjuster.
Test the service brakes
● Fully apply and release the service brakes five times using the tractor brake
pedal.
Check the slack adjuster angle
Note!
Slack adjusters must be adjusted manually. They require periodic
adjustments to ensure optimal braking performance. Lubricate slack
adjusters with grade 2 PRECISION
TM
XL5 MOLY EP2 grease (or
equivalent) after the first three months of use, then every six months.
Using a grease gun, add a small quantity of grease in the grease fitting
(2). DO NOT overfill the grease chamber to avoid damaging the seals.
● Apply parking brakes of the spreader and check the adjustment of each
slack adjuster;
● When the brakes are fully applied, the slack adjuster (3) must be
perpendicular with the booster rod (4), as illustrated below;
● If it is not perpendicular, repeat all air brake calibration steps.
