NOTE

Assistance from Unit Maintenance is required to cage or uncage brakes.

Cage Brakes. In the event of an air pressure loss, spring brakes on the rear axle will apply the brakes. If the vehicle must

be towed and there is not enough air system pressure to compress the power spring in the spring brake chambers to release

the brakes, compress them manually. Each vehicle has two spring brakes.

WARNING

Brake chamber contains spring under great pressure. To prevent personnel injury, avoid working directly

behind chamber. If caging bolt will not engage properly, spring may be broken.

DO NOT remove clamp ring around spring brake chamber. It is under tension and can cause personnel

injury if released.

When caging brakes, block wheels to keep tractor from moving when brakes are released. Failure to follow

this warning may result in death or injury to personnel or damage to equipment.

Block wheels.

Remove cap (3).

Remove nut (4), washer (5), and release stud (2) from stowage pocket (1).
