1944 M20 Armored Car hydraulics

[Chad Lares]

I'm having a hard time finding the seals to do a rebuild on the hydraulic systems in the M20. Specifically, that little plunder in the gas pedal, the ones for the master and slave cylinder in the clutch. Let's go ahead and throw in the one in the master cylinder for the brakes as well.

Can you list who you have reached out to for these parts?

Wow that’s bad news. None of those guys had any advice for this? Back in the day, you could take the master cylinder casting number into a NAPA store and get kits. I remember the clutch master cyl was the same as a brake master on forklifts and the brake master is the same as a CCKW or M135. Once you finally get everything rebuilt, it’s a nightmare to get the systems bled.

This is the fourth rebuild of the hydraulics. Ran out of seals. yea, bleeding it isn't an issue, just the seals. Have done this enough over the years.

You must be using DOT 3 brake fluid. Switch to DOT 5 and never have to rebuild again ever.

 

[Chad Lares]

would love to... except I need the seals first... which seem to be non-existent.

If it comes to this, this business in Houston can manufacture anything seal related out of any material. They make packing type seals for me constantly.
