Mack CF Posted January 2, 2011 Share Posted January 2, 2011 73 CF, all air brakes. Recently the brakes have been grabbing really hard at low speeds, and the parking brake light is taking longer than normal to go out. It goes out a minute or more after the brakes have been fully opened from air pressure. Any idea what it is? Quote Link to comment Share on other sites More sharing options...
David Posted January 3, 2011 Share Posted January 3, 2011 Charge the air. Take the parking brake off. Put it in gear. Shut it off. Listen at the parking brake chambers and quick realease for leaks. Quote Link to comment Share on other sites More sharing options...
