Master Cylinder Upgrade

[Stevepipeman]

My OEM master cylinder on my 71 FJ40 won't hold pressure and needs replacement. I converted the to front discs when I did the resto 3 years ago and read at the time that I could have updated the master cylinder to one proportioned to 60/40 distribution. At the time I removed a restrictor from the front circuit of the old master to increase fluid volume to the calipers and they worked okay. Now that I need a new one, can anyone tell me what later Land Cruiser application would be best to be used for front disc/rear drum combination?
Thanks

Everybody who's anybody (like me) has been using an 80 series non-ABS brake master with good results.

With drum brake rears?

Good time to upgrade the rears to discs.

With drum brake rears?

I'm not sure that it really matters much. In my limited experience anyway.
I did the Toyota disc swap in '04 and just used the stock '74 MC. Put disc rears on in '10. Still with stock MC. Just recently put on a Cityracer booster and Napa 80 series MC.
Always had good brakes. Never felt the need for a proportionning valve.
I'm aware of the different cylinder bores and stroke lengths and stuff, but i don't autocross or drift and don't know if I've got a 60/40 bias or not.
Yes, these are brakes we're talking about, and we're supposed to be super smart and well informed when fooling with them but it's hard to go wrong mixing and matching LandCruiser parts.
The 80 series MC has been swapped into a lot of earlier rigs, I've yet to see the thread "OMG!, never run front discs and rear drums using an 80 MC".
So I'll go out on a limb here and say Yes, even with drum brake rears.

I now run the 80 series on two of mine. The earlier Non ABS one. Both with disk front and drum rear. I run the stock OEM Prop. Valve that attachs to the booster.
Here in Delaware we have to go through a State run D.M.V. inspection facility. They actually do a brake stop test that measures the front to rear bias. Both work and pass. You will still need to adjust your rear Drums occasionally.

For my 73, I swapped in a MC from an early 90’s Toyota pick up. Worked well with the disc swapped front end and stock drum out back. When the drums finally gave up the ghost, I used @Poser rear disc kit and the same cylinder. Working great to this day.

Thanks for your experience. I definitely want a MC that's used with, at least front discs and for everything I've learned since posting this thread. Looks like the Non-abs MC for FJ80 is the way to go.
