dual chamber master

Can someone suggest a dual master cylinder for my 53 customline. I am not going to disc, I just like the safety of 2 chambers.

has this mount for 41-48 Fords to mount the Mustang M/C. Might be of help on your '53
 
any other valves needed? Proportioning, etc? Or is it just a line out to the front and one to the rear with residual valves in each line?
 
You won't need the adaptor for a 53. A Mustang drum/drum MC should bolt up to the lower two studs. The piston diameter should be a match for the stock unit so the pedal will feel the same.
 
At the risk of hijacking this thread, but same subject, is there a dual master set- up available for a 1950 shoebox? Thanks,
Howard

I bought mine from the old Butch's Rod Shop many years ago for my '51, but are now available from Jamco, ECI and probably others. The '49-'51 Ford master cylinder also supports the clutch and brake pedal assembly, so most kits simply relocate the new dual master towards the rear, near the transmission cross member, and connect to the stock pedal through a long HD push rod.
 
Thanks Bob, I wondered if anyone would bother casting a dual unit, that strange, for the short '49-'51 application. I'll look into the sources you suggested.

Howard....I just bought one from ECI. Looks like a real nice unit....called them on the phone and they were very nice to talk to. Reasonable price, complete, nice work. Google them.

Same here,need residual valves,but works good!

I just have a residual in each line, no proportioning needed.

The last three I bought had the residual checks built into outlet ports; just like they are supposed to be; tho it's a good idea to check that they are in place, especially how and where parts are built now-a-days.

When adding a dual cylinder be sure to check that you can obtain full stroke of the master before hooking up the lines, bleeding, etc; otherwise in case of a failure you may not have enough travel for the "good" side to do any effective braking. Take the carpet and padding that may be added later in account too.
 
Also note the port nearest the operating rod is for front brakes.

This port is for the FRONT brakes....

The FRONT PORT, furthest from the PUSHROD is the secondary chamber....supplying the REAR brakes.

Not always. There are some vehicles that have the rears plumbed to the primary piston/chamber. The larger chamber, if obvious, always goes to the fronts on cars and light trucks, whether primary or secondary.

Ford actually had to bother casting one for the '67 Econolines, as they had been using the '49 '51 master from when the Econolines were first introduced, then the dual chamber master cylinder was government mandated for the '67 model year. It was the last year for the first version Econoline, and really hard to find a '67 master cylinder now. ..B.
 
Barlea, who woulda thought? This is why I participate on this forum. Was a proportioning or residual valves used with or in the Econoline dual master cylinder? Are rebuild parts available for them? Heading for Rhinebeck in a couple of weeks and will keep my eyes open for one of these odd ball units. Thanks,
Howard
