Power brake booster

[thormotorsports]

I have seen quite a few boosters on FJ40s. What is the best one to use? I take it that the bracing on the firewall needs to be cut to install the booster. Thanks for your help, Al

You can use lots of different ones, I used a 94 Toyota truck booster and master. I also used the adapter from JTOutfitters to clear the rib on the firewall, and adapt the three hole fire wall mount to the four bolt booster.

Oh, and you will probaly get lots of responses telling you to search. There is tons of info on here about doing this.

I'm in the process of adapting a system from a 2500 silverado. It uses the power steering pump as a booster instead of using a vaccum type. Tons more pressure.

I'm thinking of going this route on my 67. Does anyone know if I'll have any issues fitting it in there? I just don't want to drop $60+ for something I wont be able to install.

Does this used up less room in the engine bay? The brake boosters are big and ugly.

can you run the mini truck master cylinder as well or should you upgrade it to a larger bore master? I have drums all around btw.

Yes, you will have issues. You can either cut the firewall brace, graft in a later firewall section, or get an adapter like the ones Wardens used to sell. I think Mark A. on here was selling them at one point, not sure if he still is. JTO does, but you would better off with mark if he is still doing them.
It is not a quick and easy swap, but it is doable. I used a 94 4 runner booster and master.

I have 4 boosters (2mini/runner and 2 fj40) if anyone needs them, PM me. $30 ea. Somehow I ended up with a pile of them.
