1940 Brakes

[funrunr]

Hello, I need to find a master cyl that will fit in stock location that has dual resevoirs. I was told that the 69 mustang has a lower profile cyl and it might fit? Instead of buying another one on a guess, I would like to go the tried and trued route. I bought my disc brake conversion from Magnum axle and they said that 79-87 chevy would fit, but I can't get the lid open in the stock location without modifying.
Please pass along any tips you may think I could use.
Thanks, Mark

Do they offer a remote fill set up?

I've done this numerous times and it has worked out very well.

www.mr40s.com has a nice drop down adapter for the stock 40 pedal setup - you then use the appropriate year Mustang drum-drum or disk-drum MC. Just ask them and they will tell you what one to use. I have this same setup in my 40 coupe now - I'm using DB up front, no power.

Presently I'm using this same adapter in my 40 p-up project but I've also added a power booster through another adapter. THe wife would love to drive this truck and she is more familiar with PB vs non-power.

This unit will be too long/heavy for just the drop down adapater and I will install another support off the MC mount up to a bar off the frame rail(s). Here are some pics to gve you an idea of the adapter and my setup ....

On my '36 with '39 pedal assy I used a low profile Wilwood dual res. from Summit Racing. I tried the Mustang but it was too tall and hit the floor pan. It's a little pricey but worked great. Make sure you get a 1" bore.

Thanks for the input so far, as with TomT's looks like it would solve the problem but I would need to add a new hole in the floor to check the fluid.I am leaning more towards gkgeiger's solution being able to keep everything simple, the car has a new floor and I don't want to cut it.All three solutions are definately good ideas and iI appreciate them all. Thanks,Mark

With the drop-down adapter you can fill it from underneath - it's what I do.

My suggestion for the MC is NAPA #39037, 7/8" bore and ports are facing the frame.About $41. Used this MC many times for disc - drum and disc-disc with no problems (stopping).
