Turn off the engine. The pedal should move with light pedal effort for approximately one quarter of the total travel. At this point, pedal effort should increase substantially. If the engine is turned off, the brakes may be spongy. The brake system accumulator is depleted. Start the engine in order to charge the brake system accumulator.

Note: Consult any CLAAS dealer, or refer to the Service Manual for the procedure for purging air from the brakes and for troubleshooting. Do not operate the machine until the brakes are functioning properly.

The transmission control should be in the NEUTRAL position and the parking brake should be engaged before performing this test.

1. Turn off the engine. Depress the brake pedal several times until pedal effort becomes much lighter. This action depletes the pressure in the brake system accumulator.
