Brake MC question... (1 Viewer)

1982 FJ40 stock front disc/rear drum setup...

I’ve got to replace a leaky MC and can get a roughly identical cylinder to replace it but wondered if a 80 series non-ABS MC would be a good choice with my current setup?
I have found references to this with 4 wheel disc setups but wondered if anyone had done this with the front disc/rear drum setup and found it advantageous?

This is what I’m looking to use:
OEM Brake Master Cylinder for '94 Land Cruiser FZJ80 Without ABS

I can't think of a good reason NOT to use it. Getting rid of an extra reservoir is a good reason TO use it. Pretty much a bolt on deal. You just need to be sure the push rod stroke is correct.

Yes, an 80 series MC is a good upgrade, I just did mine, but I've got 4 wheel discs. Check availability of rebuild kits for your current MC. It's an easy rebuild.

It is a good upgrade, but will make your brake pedal stiffer because its a larger size piston.

Its the setup I run and I like it.

since you have rear drums you may be better off with the virtually identical master from a 90’s 4Runner or FJ80.

The 80 series is a larger size piston? I thought it was a smaller diameter...pushes less fluid but at a higher pressure. Am I wrong again?

I use a MC from the 60 series trucks, I have Toyota front mini truck discs and late rear drums and the mini truck booster. That combination works well.

I recently replace my BB/ with a dual diaphragm BB and FZJ80 non ABS MC from city racer. Added a brake proportioning valve from wildwood. 1911 helped me throughout the process.
Nice upgrade

My setup, you can see not much clearance between the booster and intake manifold.

working on adding this:
