I did on my truck and the brakes work wonderful! I used the hydroboost, master cylinder, proportioning valve, and the lines from the MC to the proportioning valve from my bread van, then just hooked my brake lines into the valve.I was wondering if I could use the hydro boost master cylinder off of the 1985 wonder bread van that I got my engine from to run the brake system on my 1973 4x4 1/2ton dodge truck? And also what do you use for lines to mate the two? Thanks
Yes, exactly. I mounted the bread van proportioning valve down on the inside of the driver's side frame rail tweaking the factory bread van lines as I went, and then ran all of my hard lines on the truck to that. However, my brakes are not factory IH pieces. I have installed 3/4ton Chevy axles in my truck (D44 front, 14 bolt rear) and I have 1978 Chevy 3/4ton 4wd front calipers, rotors, and hoses in the front, and 1978 Chevy 3/4ton 4wd rotors and 2wd calipers and hoses in the rear. The truck stops incredible with four wheel disk brakes and will not lock the rear tires before the fronts, unless I am on a very icy road. With the hydroboost, fat tires, and four wheel disk brakes my truck stops better than my old beater 91 Accord! I think that the fact that the master cylinder was designed to work with a big wheel cylinder in the rear (1 ton) is what allows it to work as well as it does with my calipers in the rear. I am not sure though that it would be a good idea to run 1/2 ton brakes (especially in the rear) if you keep the MC from your bread van; I imagine the brakes would be very touchy that way.So you used the everything from the van up to the valve and just hooked up the truck lines into the valve from the bread van and it works ok?
What type of stuff does the brake shop do? Do they specialize in conversions, swaps, and transplanting brake system parts? If not, I can't see the benefit.thanks guys for the help i am going to get some help for a local brake shop that does this type of stuff. it may be a little pricey but i would rather have it done right.
I agree. If you can swap an engine, I'm pretty sure you can figure out how to do the brakes.Braking systems are not complicated, and if you are going to perform something as involved as a 4BT swap then you definitely have as much mechanical inclination as anyone working at the corner Midas shop.
