I would like to use the old style Ford master cylinder as in my pic here. My question is what would be any actual difference in ...say, for example using one out of a 71 torino or using one off a 79 bronco and so on. Is there any actual inside valving differences between the different ford applications? I see buying a GM master cylinder the main difference is the bore size. If you look in Speedway they sell a Ford one like this...but I only see the one. I am having the 11" truck drum brakes in back and a Speedway brake kit with GM metric calipers in the front on a coupe. I am looking at using one that fits a 73-79 Bronco, Pickup and econoline. Other then maybe adding an adjustable proportioning valve and the inline valves as needed if too low, wouldn't this work ok?
I just went through this dilemma myself in the last few weeks . I looked & looked to try to find one that I wanted to use . Most that I found from the era were 15/16 Bore (a couple were 1" bore) . I looked purposely for one that was from a car/truck with drums (rear) and discs (front) originally , and had no booster so that it should work correctly with my application . I ended up using one from a mid-60's F-100 . We used a Mustang 2/Granada master in my friend's Shoebox (which works great) , and I was fully prepared to use one but I wanted to use one with the lines going out the other side (I have room that he didn't) , so the search was on . Long story short (too late , lol) , I'd look for one from a car/truck with a similar brake setup with the lines coming out the side you need & go for it .
The differences are bore size, whether the ports are on the left or right side, and residual pressure valves for 4 wheel drum, disk-drum, or 4 wheel disk. I don't think one master cylinder part# would be correct for 73-79 Bronco, as up through 75 they were 4 wheel drum with the ports on the driver side. 76-77 were disk-drum with the ports on the p***enger side.
relic you're right. I stated too much of a generalization on the applications. Looks like this instead... 76-77 bronco, 75-76 E100, E150, 73-79 F100, 75-79 F150, and 73-76 F250 I think these all would have disc/drum and the line coming out either side would be fine for me. It also has a 1" bore and I know the GM ones want a 1" bore for disc/drum. I think I should try it, what do you guys think?
I have similar brakes that you are using. I choose to use a M/C from a Mustang II with 15/16 bore that was disc-drum spec. I am very happy with this combination.
Give the guys at Master Power Brakes a call, 888-351-8781. All they do is brakes for Rods and Customs.
Yup , any of those should work , depending on which side you need the lines on . If you need the lines on the other side , the Mustang 2 one will work just fine with the 15/16" bore .
