KNicholas2 Posted September 25, 2007 Report Share Posted September 25, 2007 For increased safety, I want to put a dual master brake cylinder in my 1942 P14. Can someone recommend where I can get one? Kim Nicholas Seattle Quote Link to comment Share on other sites More sharing options...
grey beard Posted September 25, 2007 Report Share Posted September 25, 2007 Kim, I'm listening pretty hard for the answers you will get on this one - been asked many times, and the only work-around I know of that really works involves moving the steering box forward about 5/8-inch. Sure would be grand if someone here in the midst of all this MoPar think-power could come up with a part number that would fit in that too-small space where the original lives. The hydraulic plumbing part is a snap - it's just a matter of finding enough room down there for the dual version. LOL Quote Link to comment Share on other sites More sharing options...
Brendan D25 Posted September 25, 2007 Report Share Posted September 25, 2007 There were some pictures on here awhile ago of a dual master cylinder setup.Maybe you could put in a search on this forum for "dual master cylinder" and you may find it. Some have used a firewall mount from a later vehicle. Brendan. Quote Link to comment Share on other sites More sharing options...
40desoto Posted February 26, 2013 Report Share Posted February 26, 2013 (edited) Not sure if this will work for other years but I made a bracket that that allowed me to mount a dual master cylinder (I belive a 1967 mustang dual was the smallest i found) right in front of the original location and just clears the column. Picture attached.. PLease dont laught but this was a mock setup to test clearance etc.. I will refabricate bracket with thicker steel Edited February 26, 2013 by 40desoto Quote Link to comment Share on other sites More sharing options...

I'm figuring since this all so close it would work in my P15 as well. I'd be interested in seeing photos if you have them. Thanks ahead of time. FG.

55 Fargo Posted February 27, 2013 Report Share Posted February 27, 2013 This always a great topic, and always enjoy seeing how some of you have fabbed in a dual MC. These more modern MCs are used instead of the single pot originals for a variety of reasons, and safety being #1. A lot of us are still using the original single pots, are they dangerous? How many of you Guys have had brake failure as a result of a bad original type MC? I do realize, if a wheel cyl blows out, a single pot will be emptied and useless, and the dual mc, will leave you with some brakes. I am only mentioning this, to actually discover how many have had major brake failure, with a stock hydraulic system.... Quote Link to comment Share on other sites More sharing options...

P15-D24 Posted February 27, 2013 Report Share Posted February 27, 2013 Don't think a dual master will save your bacon if you have a failure. I had a Dart that had dual master, had an on the road failure and the remaining stopping power was much less than the emergency brake. As moparbenny said, maintain your brakes!

Don't think a dual master will save your bacon if you have a failure. I had a Dart that had dual master, had an on the road failure and the remaining stopping power was much less than the emergency brake. As moparbenny said, maintain your brakes! Yup, just 2 days checking MC on 1955 Fargo, noticed it got low, checked all wheels, and found the culprit, left rear wheel cyl, which is a diff from an 1988 Diplomat, $13.00 for new wheel cyls each, some new brake line, and back in business. I was not enough of a leak, or I caught it in time, brake shoes are fine, only 400 miles on those shoes. I did not replace wheel cyls ,when I did brake job, they were lookin okay, guess I should have.... Quote Link to comment Share on other sites More sharing options...
Robert Horne Posted February 27, 2013 Report Share Posted February 27, 2013 To leave the original brake/clutch pedals in place is a big plus when adapting a newer MC. I used a simple piece of angle iron, a longer push rod, and a Mustang II MC, on my 48 Dodge, worked very good.... Many here have done something similar...

This is excellent. This is exactly was I was aiming for but I did not weld any support to the frame. I simply mounted and extention to the original master mounting holes. When I do take the Body of the frame I will do just like you did. My setup is currently working but worries me that the master seems to move a bit when I press the brake pedal Quote Link to comment Share on other sites More sharing options...
40desoto Posted February 27, 2013 Report Share Posted February 27, 2013 Was the original master cylinder under the floor like my 47 is? The original on the 40's was under the floor but right in front of the brake pedal itself. not behind it Quote Link to comment Share on other sites More sharing options...
55 Fargo Posted February 28, 2013 Report Share Posted February 28, 2013 Had to replace a rear wheel cyl (1988 Mopar 8 1/4 diff), was leaking on the toward front side of wheel cyl. I installed a new wheel cyl, the brake line from T junction on the diff, this went well, very little brake fluid messed up inside the drums. The brake shoes, hardware, drums are new with only 500 miles. After bleeding brakes, I have a slight leak in the new wheel cyl, and same side as the old wheel cyl go figure. I also notice my MC has some leaking going on.....Lots of fun. I am going to go through all again, maybe rebuild or replace MC, all shoes are new, drums machined, but hydraulics now acting up. I wonder what other dual MC might be a good candidate for a 1955 Dodge pickup... Quote Link to comment Share on other sites More sharing options...
