Thread: '30 Ford Brake/Clutch Pedal?

Tweet

Hey thanks guys! I will definitely look into a couple of these options. The link to the Deuce Frame Company was the one I had on order when I was told that he lost his supplier and had none on hand.

I have some calls to make, Thank you again,

32_40 I will definitely keep this in mind, I just don't know how much fabrication I am comfortable with on this specific peice. Just learned to Mig and working on my Tig skills

No worries.

The pedal actuation ratio is very important. You can't buy any pedal assembly, put a vacuum booster on it, and expect it to work properly. A lot of folks have posted problems, getting the correct combination of pedal ratio to work the particular master cylinder and brakes that they are using.

I bought a body/chassis, with a 7" single diaphragm booster, 3.8/1 pedal ratio and 1" master cylinder, but found the braking unimpressive with my high-dollar Wilwood disc brakes. A 7" dual diaphragm was better, but still not as powerful as I wanted.

I called Wilwood and got a recommendation for a minimum 8" dual diaphragm booster, to use with their brakes and a 1" master cylinder. I went a step further and reduced the master cylinder piston to 7/8" for more pressure. Now I've got brakes that are as easy to work as any new car.

A typical manual pedal assembly would have a pedal ratio in the 6-7/1 range, to use with a 1" master cylinder. Of course, it requires more pedal travel, than a boosted setup.

Vacuum boosters may also be troublesome if you've got an engine with a big cam and low vacuum. A hydraulic booster may be the answer.

Really?

Okay that just made the decision for me. I have a few numbers to check now but I will go with a power set up from the start. Looks like I will have an extra MC....maybe I'll save it for my next project

Thank you much,
