Run down thru a ditch loaded with dirt and rolled to a stop. I was luckly I didn't kill anyone. Single master clynder, booster under the cab. My thought is to pull the booster and twin clynder out of a 1 ton cheby I have sittin here (the one where both res are the same size) and run one front and one back. Remove the booster under the cab. That way I would still have something to at least SLOW me down should this happen again. Anyone done anything like this? I am picking up all new lines today, to fix whats there, but would like to get this, or something done. I don't have enough underware, and was just to d@mn scary, to do that again.

Before you commit to the route of swapping though, check the bore diameters of both brake cylinders as well as piston travel within the cylinder. I suspect you will find the Chevy dual piston to have a slightly smaller piston, and shorter travel. There is a small chance that you might find a larger size Dodge chassis cab that had been equipped with a dual piston (most likely a bus application) that would potentially fit up a bit better.   [Reply]  [No Email]

Most big trucks have only one line off MC, even in later years. I don't think your smaller unit will give enough volume for bigger wheel cyls on dump truck, but not sure. Most one-ton or bigger GM's had hydraulic booster run off PS pumps, not sure if Dodge had such a rig or not. MOst park brakes run off back of trans, are easy to fix if needed, and can be re-lined easily. Usually just a Band around drum, pulled with lever on floor next to shifter. It's your back-up, I would get it working also.   [Reply]  [No Email]
