The Stovebolt Site Forums The Shop Area Driveline Brake bleeding on my 1961 C40

I am well aware of the various bleeding techniques, but does anyone know of a master cylinder top with fittings that can be used with a pressurized top side brake bleeder for an original style 1961 master cylinder? I had a vacuum one and it worked well enough, but this would make it ten times easier and faster. The adapter that came with the bleeder must be for later years and bigger master cylinders.

High Plains - Is your master cylinder the single chamber for brakes only, or the side by side dual chamber for brakes and clutch operation?

It's the side by side, I'll grab a picture of it

What about something like this Adapter plate assembly???

If I did the math correctly, it looks like the plate is about 3-5/16" x 4-1/8" and should span your side by side dual master cylinder. You just mount it long ways across your chambers long side and it should properly cover the chamber and still fit without interference against the firewall, I think.

You could even fabricate a similar plate to specifically fit your application using common materials from a hardware store.

Looks exactly like what I need, the bleeder came with something similar but was about double the size and had two holes, tried to make it work but it didn't. Will probably just order that and be set

This is my bleeder. I clamp it to the master cylinder with a C" clamp. Hook it to compressor and adjust pressure to 5 psi. Check fluid level after a bleeding a wheel cylinder by cranking pressure back down and refill master cylinder as needed. Works like a champ. The bottom is a layer of 3/16" rubber matting.

If it's the side by side dual master cylinder Hydrovac system, it will gravity bleed. The one in my bus has, several times.
