More on Master Cylinders

Still no success in my quest for a good fitting MC (good fitting without a lot of mods) I've been looking at 68 mustangs and as good as they are, they won't quite make it. I've started to really look far afield. I'm thinking of one of the newer ones with a plastic reservoir, mounted remotely. Anybody ever try this? How did it workout? I have to be able to get under the cross channel and take the cap off to fill it. Any small foreign ones that will work? I was even looking at the ones for a Clark fork lift. Maybe a Kubota or something?

If there is anyone who can help you it is Richard Lacy of Early V8 Garage in California. He is a flathead guy, but I bet he knows a lot about Model As.
 
Look up VW beetle/ghia/bus/thing masters, their relatively small. Same with chevy chevette or s10 with manual brakes.

what about things like corivairs?
 
I agree with Ray on this. You can't brake any harder than full lockup and that is very possible to do with mechanical brakes. And, if you lose one hydraulic brake, you are done. If you lose one mechanical brake, you still have three to stop you.

or in the case of my bailing wire truck, one emergency brake, and 2 fronts haha rears were disconnected and ******* out of the way.
 
OK Here's the deal! I don't have a proper cross shaft and without it I'm limited to a direct, inline pushrod. I don't know where to find a cross shaft. I think if I had the ALL the parts, I'd put the mechanicals back, but I don't have them either. JR-41, Thanks for the suggestion, but I've got one of them from Speedway and I can't make it fit without it near dragging on the ground. It was also suggested to get a 68 mustang, which is smaller, yet in comparison with the 40 ford that was there, it's still too big.
Picture this, The MC is bolted to a plate which is bolted the front of the channel/ cross member and in line with the brake pedal. The MC is mounted to the backside of the plate and is under the cross member (Can't get the cap off to fill it) I see some modification coming up unless I can find a MC small enough to fit. And I thought this would be easy!

Try Laine family website, he has done the conversion to hydraulic brakes using remote reservoir in 31 coupe. His post is full of tips and illustrations you will find very helpful.

The problem is that you need a master cylinder that when combined with the correct linkage will produce the right volume and pressure. The early Ford wheel cylinders needed a lot more volume than the current master cylinders are designed to produce.

A Voltswagon master cylinder might work for you. My 68 Dune buggy uses a 68 m/c that has the reservoir mounted inside the car. Under the dash and away from the m/c itself.
 
anyone ever watch Fast and Loud, they used a mastercyclinder on a few A's

mounted to frame under floor board and has linkage to connect it to the brake pedal.

I looked and a late 60's early 70's VW transporter with power brakes
uses a 15/16" bore MC which might be big enough to work.

Thanks for this site! I really appreciate it. Nice job! He had a load of crap to start with and made a nice, clean professional job of it! Now I have a new, previously unknown to me, problem. The arm on the brake pedal has been reversed! My lack of familiarity (Ignorance) didn't allow me to see it until I was checking out the pedal on my T.S. So start with a fresh, unwelded pedal and I may duplicate what he has. Except for the 1 to1 ratio of the of the reversing lever. I'll go something like 10 to 9. Thanks again!

ohhh didnt know that about the ford cyl...hmm i know some people with chevettes put a 70's corivette master on for better braking ratio...
