Thanks for the info. With my current set up I have to lift my foot off the gas and over to the brake pedal, so that wouldn't change for me. And my pedal sticks out much further than original. But my braking power with the current setup is not great. Unfortunately if I ever change it out I will have a big hole in the firewall that I would need to fix.

Kevinpackard,
Have we discussed you setup? I don't recall if it was you or someone else I talked to about their setup. Either your booster is too small, master cylinder bore is incorrect or the pedal ratio. Do you know the answer to those items? Earl

Sure glad I wasn't driving the car till the treadle-vac is converted. I was taking pics for ABS Brake and I lifted the OE booster up finding the underside covered in brake fluid. The previous owner said I could hop in the car and drive it across the country. Lol Mind you it has 30 plus year old all cracked up tires on it too. Guess he likes to live on the edge. Lol
The earlier cars have an area cut out in the toe plate for the accelerator pedal rod. The later cars must of moved the throttle rod further right as their toe plates don't have this notch. So they want to add it. I told them it's no big deal as I will trim it with my plasma cutter when I cut the clutch hole in the new toe plate.I sent their builder a ton of pics and measurements. Sounds like they are going to borrow my OE plate. This should allow them to cover the earlier cars better. Earl Attach file:  IMG_20240212_175803116.jpg (3,997.47 KB)

The question I have has anyone used this booster/master cylinder on a drum braked car with torsion level suspension. Brake pedal being higher than stock not a problem in my view as most old cars had brake pedal higher than throttle as well as clutch. Looks like best replacement for tredlevac being new parts as apposed to 68 year old parts .

I can't speak for the torsion suspension part, but the ABS kit would work on drums. Just let them know as you wouldn't want the 1 1//8" bore on drums. You'd want a 1" bore or smaller for drum/drum power brakes. You'd also need a 10 psi residual valves front and rear on drum/drum as close to the master as possible. That keeps the cups expanded in the wheel cylinders and makes up for the overcoming of the springs. Will keep your pedal travel down and firm.

Quite a regular

This looks like a great kit. Is this something they have available to order or did they custom make it for you? I'm interested in purchasing one for my 55 Clipper.

Quick update. Do not order the ABS kit for the earlier cars at this time. I'm working with them. There is fitment issues. I will do a full update tomorrow when I have more time.
