The Stovebolt Site Forums The Shop Area Engine Shop changing Routing of lines from single to dual Master Cylinder?

I've searched the archives and can't find a diagram or a detailed description to change the routing of the brake lines when you install a dual master cylinder that will replace the original single m/c . I'm installing front disc brakes on a '59 . Thanks-

Try Brothers. They're on our links page. There's a good picture "How To" there. They go over the hook ups with some good tips. I just finished the dual master cylinder up grade on my '59 using the stock drum brakes. I needed to mess with the length of the push rod a bit. (bought a long Grade 8 bolt and cut it to lenght). The only thing I think I need now is residual valves. I get a better feel from the brakes if I pump them. I hope you don't forget to bench bleed the MC like I did! I think I got all the air out now but when the res. valves get here, I'll bleed again.

Thanks but the Brother's site does not, at least that I saw, give instructions as to what lines to run to the front or rears. In fact the most I got out of that site was their patting themselves on the back for installing another access hole to help fill the M/C. Hate to tell them there's a door available that gives complete, unrestricted access and is a much cleaner install..oh well. I'm under the impression that one line goes to three wheels and one to one wheel on a single M/C while a dual requires one line to the two front wheels and one line to the rear wheels. I'll be running all new brake lines so I need to know the placement of "T" and other fittings. With so much of this being done it should be recorded somewhere. Can somebody whose done this give simple instructions? Thanks.

Try this.

d9r ,you mention you are using aJust finished installing a dual MC on my '51 GMC 1/2 ton. I ran 1 line to the front tee and then branched over to both wheels. And one line to the exsisting back tee. Not the preeties install but until I do a frame off it will do.
