For vehicles modified for trash collecting, the dump cylinder is not in an appropriate position, and therefore, when the vehicle with load bounces over something like a bump or a pothole, the brake pipe bracket above the rear differential, or both the brake pipe and the brake pipe bracket may interfere with the dump cylinder. If this problem is left unattended, the brake pipe may be damaged, and in the worst case, brake fluid could leak, which could result in reduced braking efficiency.
