The Stovebolt Site Forums The Shop Area General Truck Talk Jammed parking brake

Have you lubed all the friction points from the front of the cab to the pivot points on the crossbar? Are the E-brake cables frozen or rusted in the sheaths? Is there anything in the brake hubs rubbing or interefering with the mechanisms? If all else fails try separating the front and back components from the crossbar to see if you can isolate where the problem lies or if the crossbar is frozen in the frame supports as mentioned above. There is also a return spring that could have broken.
