BRAKE ADJUSTMENT
A.
Manual Adjusters.
1.
Jack or hoist wheels free of ground.
2.
Remove dust cover from adjusting slot two
places on each brake.
On RD type brakes the adjusting slots are below
the forward and above the rear power unit.
If star-wheel adjusting bolts are not found at
these positions, the brake had been assembled
on the wrong side of the vehicle.
3.
Adjusting bolts have right hand threads. With an
adjusting spoon, turn the star-wheel until a
heavy drum drag is developed.
Then back off
the bolt to a very light drag on the drum.
Repeat for other shoe on the brake. Replace
dust covers in adjusting slots.
Repeat for other
brakes.
NOTE: Recommended adjusting spoons, are Snap-On-
Blue-Point S-9523, Wizard 4-H-2530 and Proto 2006.
