Master Cylinder
 

Is there a duel master cylinder that would work with the standard brakes on my 50 Ford pickup?

Re: Master Cylinder
 

I think JAMCO has a conversion kit in both power and standard brake systems.

Early Mustang dual, (I think the 65-6 may have been singles) so around 68-70... This is just a memory of some one elses deal... Karl

Mid to late 60's GM for drum/drum. It has the residual valves built in.
I had this setup on my '51 Merc. which has the same size brakes as the '50 Ford pickup. The cover may be different than the one shown.

Use something like the Napaonline site to find a dual M/C that has the same piston diamter as the stock unit. I am running a '68-'70 Chevy/GMC C20 unit in mine.

Re: Master Cylinder
 

Karl is correct: 67-68 Ford Mustang is a good fit.

Re: Master Cylinder
 

Either the Mustang or the GM will work. All depends where you want the brake line fittings to be. Mustang towards the center of vehicle, GM towards the frame rail. You will also need an adapter plate. such as sold by ECI.

Changing to a dual master cylinder seems like a fairly easy thing to do on our trucks but the one problem I see arise from doing this is accessibility to fill the master cylinder. The stock unit is a pain to get to, having to worry about something falling into it while removing the cap, checking the level and filling. The updated master cylinder will have a larger cover which will be more difficult to access through the round hole. I'm currently working a '37 Buick and am installing a dual reservoir master cylinder but on the Buick it is a lot more difficult because of the construction of the frame. I am going with a remote fill system with remote reservoirs mounted on the firewall. Just a thought for you guys to consider.

I'm building a 51 Ford pickup....I'm using a 1982 Ford F350 disc drum 1.062" master cylinder. How do you tell which port on the master cylinder is for the front disc and which is for the read drums? Can it be determined by the port thread size? ANY HELP

Re: Master Cylinder
 

everyone always seems to concerned about being able to access to new m/c but really how often do you even think about it? unless it fails it's normally forgotten. drilling a small hole in the floorboard that a 1/4" tube can fit through is all you really need to fill m/c with.

Re: Master Cylinder
 

On all-metal disc/drum masters with full size caps, the larger (obvious) chamber always goes to the fronts.

Re: Master Cylinder
 

The larger reservoir is for the front. Are you running 4 wheel drums or disc/drums?

I'm assuming that the master you have is a disc/drum master. Yes? If so and you are going to run disc/drums, you will need two residual pressure valves (10 lbs for the drums, 2 lbs for the discs, plus a proportioning valve.

If you are running all drums, then you will need two 10 lb residual pressure valves, probably not a proportioning valve (again assuming a disc/drum master.)

Re: Master Cylinder
 

To fill on my 39 pu with a duel set up I just made a 3" hole in the floor board and cap it with a large rubber seal to fill the hole . All you need to do to inspect and fill if needed is pull up the floor matt.

Re: Master Cylinder
 

Yes, I'm running disc and drums. Forgot to mention that I'm running firewall mount also, so probably won't need the residual valves. Isn't that more for master cylinders that are low and possibly under the caliper level? Or should I run residuals anyway? I've always thought that the large chamber on the master cylinder was for the disc brakes, but was recently told by someone that I was mistaken. Needed to confirm....Thanks

Re: Master Cylinder
 

You won't need, or want, a residual to the front discs with the firewall mounted master cylinder, but the rear drums should have one, either internal in the master or a 10 lb inline external.
Whoever that someone is who "told" you is wrong-the larger chamber ALWAYS goes to the fronts, drum or disc.
