I have a 51 GMC 1 ton heavy fire truck and bought my disc brake setup from Dave. I also bought the dual master cyl and booster which installed in the stock pedal position from another vendor. The master cyl set up clears the PTO and the disc brake brackets from Dave used 2011 Chev van 1 ton calipers and rotors.
Get the remote reservoir, Daves kit, retain the stock steering rod, new vacuum booster/master cyl and CHEV van parts and you will be very happy. I retained the rear drums and now my truck stops on a dime with ease!
Call Dave Chapman!
