Information:

Service Brake Holding Ability Test
Personal injury can result if the machine moves while testing.If the machine begins to move during test, reduce the engine speed immediately and engage the parking brake.
Start the engine. Raise the implement slightly. Apply the service brake. Release the parking brake.
In the Messenger, enable the override for the transmission neutralizer.
Make sure that the autoshift control is in the OFF position.
Move the transmission control to THIRD SPEED FORWARD while the service brakes are applied.
Gradually increase the engine speed to high idle. The machine should not move.
Reduce the engine speed to low idle. Move the transmission direction control to the NEUTRAL position. Engage the parking brake. Lower the implement to the ground. Stop the engine. If the machine moved during the test, consult your Caterpillar dealer for a brake inspection. Make any necessary repairs before the machine is returned to operation.Parking Brake Holding Ability Test
Personal injury can result if the machine moves while testing.If the machine begins to move, reduce the engine speed immediately and apply the service brake pedal.
This test is performed when the parking brake is engaged. If the machine begins to move, compare the engine rpm to the engine rpm of a prior test. This will indicate the amount of system deterioration.
Start the engine. Raise the implement slightly. Engage the parking brake.
Make sure that the autoshift control is in the OFF position.
Move the transmission control to THIRD SPEED FORWARD. Then, move the transmission control to NEUTRAL and back to THIRD SPEED FORWARD. This will override the transmission neutralizer. The parking brake indicator light should come on.
Gradually increase the engine speed to high idle. The machine should not move.
Reduce the engine speed to low idle. Move the transmission direction control to the NEUTRAL position. Lower the implement to the ground. Stop the engine. If the machine moved during the test, consult your Caterpillar dealer for a brake inspection. Make any necessary repairs before the machine is returned to operation.
