7.2 EXHAUST BRAKE ASSEMBLY
Engine braking is controlled by a pneumatically-operated exhaust brake on the turbocharger and
by a constant-throttle system. For greater braking power, an optional turbo brake is available.
7.2.1 Exhaust Brake Assembly Removal
Remove the exhaust brake assembly as follows:
1. Disconnect the batteries.
To avoid injury before starting and running the engine,
ensure the vehicle is parked on a level surface, parking
brake is set, and the wheels are blocked.
2. Chock the rear tires and tilt the hood.
3. To gain access to the exhaust brake, remove the air cleaner.
To avoid injury, never remove any engine component while
the engine is running.
To avoid injury from the sudden release of a high-pressure
hose connection, wear a face shield or goggles.
4. Remove the exhaust brake compressed-air line from the exhaust brake cylinder.
