Looking for an upgrade to dual master cylinders. Running Brembo 4-piston calipers all the way around. Would love a little more pedal control & not sure a single master cylinder is the right way to go, even with proportioning valve.

Searched forums but didn't come up with any answers.

Any advice?

Ask Brembo?

Pedal Control? What does that mean?

Just saying.....

What exactly do you mean by "more pedal control"? Dual masters will take quite a bit of work to adapt and you will lose power assist.

Tooting my own horn. Installed on probalby 25 racing S30s around the world including two S30s that are running the East African Safari rally next week.

Not sure I'd want that on an street car, however.

"This is a race only part and we will not sell it for a street driven car."

I saw that on your page. My comment was directed to the OP.

Ok, thanks guys. Guess I deserved Bruce's comments.

What I'm trying to do is get more boosting when braking. Perhaps the dual setup is totally wrong.

I'd like the big brakes to feel like big brakes, ie. step on the brake & car stops more easily. It does now take more pressure than I expected & almost feels like I have no boost.

Any recommendations. Really.

Maybe try a 280Z or a 280ZX brake booster.

thanks john. I have a 280 mc now. Which booster would be better & will it work without having to modify anything else?

I'll try to post a photo of the current setup to get a better idea.

You're going to have to experiment with different boosters. There was a bolt pattern change on the booster where it bolts to the firewall. Occurred sometime inn 1973 so you might have to re drill your firewall if you have an earlier car.
