Toyota Brake booster and master cylinder that fit FJ40

[darwink1]

Most toyota 4 post boosters and masters are swappable. I ran an early 90s runner booster in my old fj60 and currently run an fzj80 nooster and 70 series master in my fj40. Little tweaks have to be made here and there since they all vary in diameter and thickness.

Where the brake booster is concerned, why fool around. CityracerLLC has the right one for your 40 at a reasonable price. Bill

If you’re running 4wheel Discs, I’d go 80 series booster & Master... designed to run 4 discs right out of the box... and bordering on too powerful as if there could be such a thing.

City racer sells a bunch of different 80 series MC. Which one is for four wheel disc setup?

Thanks for the replies. The MC and booster are the original ones on the 1973 set up for drums all the way around. We re-bled and re-adjusted all of them and still have three pumps to get the brakes to bite. It has to be the MC or booster. Since I now have disc brakes up front and drum brakes on the rear, could I just use a setup like I have on my 98 Tacoma? It has disc front and drum rear. I recently had to replace both of them on it. They share the same reservoir. Thanks again for all of the replies.

And like mentioned earlier, we took the residual valve out of the front reservoir. The rear (drum) reservoir has its still in it. Does a more modern mini-truck MC and booster fix this?

I think all 80 series were discs front and rear.

I think all 80 series were discs front and rear.

I had a '91 FJ80, and it still had drums on the rear. For a 40 with discs on all four, I think you want the non-ABS FZJ80 master. Cruiser Outfitters sells brand-new Aisin ones.

What about that electrical plug on the side? just ignore it? or is the picture not correct?

If I am reading this thread correctly, it does not appear that sorenoneill is interested in this thread any longer..........no post from him since the original in 2007, not even a thanks. I would like to thank everyone for their input on this brake subject, even though he did not.

The plug is there as shown. It's for the low-fluid-level light. You can ignore it, or wire in your existing harness connection if you want. @Coolerman probably sells the right connector I would guess.

Note also that for most 40-series applications, you will have to re-route (and probably cut and flare) the the brake lines to fit the later FZJ master cyl.
