Parking Brake Operational Check
sb mm 42.20.001
Important: This procedure should be performed prior to lubrication of the brake components.
If the brakes must be repaired, or they require adjustment, see Chassis Plumbing Diagram of the Shuttle Bus Chassis Workshop Manual for repair, adjustment, and troubleshooting procedures, or take the vehicle to an authorized Freightliner dealer.
Caution: Perform the following check in a clear safe area. If the parking brakes fail to hold the vehicle, personal injury or property damage may result.
- With the engine running, and air pressure at cut-out pressure, set the parking brake.
- Put the vehicle in the lowest gear and gently attempt to move it forward. The vehicle should not move. If the vehicle moves, the parking brakes are not operating correctly and must be repaired before the vehicle is returned to service.
Note:
