I want to upgrade the master cylinder in my 444 from a single system to a dual system so the front and rear brake fluid is independent of each other,thanks.Can anyone recommend a master cylinder I can retrofit to my 444,thanks.

The archives here may have this info. I looked but did not find a great piece and the link was on the board to the fellows website a few years back. He showed how he adapted a 80's Ford/Cougar Master under floor with brackets so that existing linkage actuated a custom, carefully measured rod into the dual M/C. was slick setup. and was a B210--maybe a Google search. If I can find , will post.
Good luck, Ken

I really appreciate your reply Ken.I didn't have much luck finding anything useful in the archives.

I was watching a Gearhead TV show upgrade a 50 Chevy pickup which had the same original under floor brake m/cyl. set-up as a 544 or 445. The piece for the truck was a bolt in after drilling a couple holes in a frame rail,M/C complete w/ pedal arm. The unit even had a small brake booster. Interesting.

I Goggled "under floorboard brake cylinder w/ booster" and got a selection of these, most on E bay, some at Summit Racing: listing was for many types , years of older vehicles. Seems like with some measuring, possible modification, one of the could work. Several mentioned for disc/drum or disc/disc w/ proportioning valve. Should work ok w/ drums F & R if lines connected to activate both together. This interests me and possibly others solely to have the Backup of a Dual Master vs.a single. However, some people here say if you have a good original, single bolt-in M/C replacement, it will be fine, along with centered, well adjusted drums all around--as long as you aren't flying at Max velocity all the time. Worth a look Let us know what you find.

You might be able to make this work.



I found this remote reservoir, but I couldn't find a USA supplier.
