Is there a different booster you can use to replace the original? Having a hard time finding one with or without a master cylinder. Every place seem to be out of stock. Just wondering if there is a newer more available model. Thanks for any help!

Thanks for the reply. I looked at that post and was wondering does it matter if the master cylinder is a two part container? The original one is a single I think? Guess I haven't done enough with converting master cylinder to know if that makes a difference.Comment

I totally agree with Yadkin (Steve). For the sake of safety for you and your family, use a dual-reservoir (dual piston) master cylinder. Every car on the market has one (for many decades, now) because the NTSB requires it along with seat belts, etc.
There is nothing worse than having NO brakes.
Yes, you will need to modify your system but it really isn't hard to do and it can be done in one Saturday morning in your driveway.
You also need a combination proportioning valve. This ties both front and rear systems together by means of a hydraulic spool. If a brake line ruptures or a wheel cylinder comes apart, the spool will shut off the 'bad' system to prevent further brake fluid loss and it will turn on a 'BRAKE FAILURE' light while the 'good side' still works as normal.
You can buy pre-made brake lines at most auto parts stores OR you can cut, bend and flare your own (which is what I recommend). Your car's wheel lines already come to a tee on your frame so you only need to re-route the lines to a 'prop valve' at the front of your car.
Combination proportioning valves are sophisticated in their operation as they;
meter, giving initial pressure to the rear wheels, then to the fronts,
tie the front and rear systems 'together' with a spool in between,
turn on a 'FAIL' light and,
if you have DISK/DRUM systems this valve lowers pressure to the drum brakes but maintains full pressure to the disk calipers.
If all your front/rear brakes are the same, (disk/disk or drum/drum) there is a different combination prop valve for that application because both systems use the same pressure.
One of our longest topics on Squarebirds.org covers changing our cars to disk brakes. Many of our members have done it and none of them have switched back. My classics stop just like a modern car. - DaveMember, Sons of the American Revolution

I was just looking at RRS and saw this. They are supposed to fit Thunderbirds as well as Torinos.

To me that looks like more trouble than it's worth. If you had a truck without a console and you were trying to stuff a big block far back in the engine bay, maybe. It's not that hard to adapt a much less expensive unit to fit under the hood of our cars.Comment
