to fit this set up . for the disc brakes my rotors are to thick 1 1/2 inch thick and the current calipers do not come with emergency brakes available , nothing i have found will fit . a

hydraulic parking brake i am not to crazy about . what about a pinion emergency brake ? and what type of emergency brake is excepted for general road use in all the USA ?

Along with the hydraulic lock you mentioned, it shouldn't roll away. Tow trucks use hydraulic locks all the time. As long as everything is, "UP TO PAR", I would trust it.

A drum at the transmission or a rotor on the pinion will hold a loaded truck, even in reverse.

He had quite a few bigger trucks in there last time I was in there. Not sure if he'd have one or not, but he may know where to find one! http://ronsautowrecking.weebly.com/contact-us.html | | | | | Joined: May 2009 Posts: 85 'Bolter | | 'Bolter Joined: May 2009 Posts: 85 | Try to Google " manual brake caliper" you'll find a lot of stuff, also try Pirate 4X4, they seem to have looked at this. Wilwood makes some they call spot calipers, I think. there are a lot of industrial application units that could work but they are pretty big. Remember that if a caliper is bolted together you can usually make it any width you want with spacers.
