Master Cylinder

Stock. Now, inexpensively available from the vendors I'm told.

Mark, Is step bore 2 different bore sizes for front and back brakes? Looks like/maybe larger bore is closest to booster? Then rear brakes have higher pressure? What does the "dual sevro" booster mean?

It looks like a good approach, thanks for the pic.

Stock master cylinder isn't an impressive system for an up-grade, after removing it to get a good look, I decide not to replace it with a factory one. Thanks.

Dual servo from Precision Proformance. I also had Bob make the Polished Stainless Lines. The way to go.

Boxxboys, which/what clutch master is that, looks like Precision Proformance, Italian version? Thanks.

I wanted something complementary to a mid-engine sports car ... so I designed this version of tandem brake hydraulics. This uses modified Tilton master cylinders and balance bar. (plumbing is temporary)

Mounts to original vacuum booster with clearance for hood.

Adjustable front to back brake pressure without proportioning valve.

Lightweight, compact design, 90% aluminum.

Integrated brake light switch.

Simple hydraulic pumping.

Isn't this like the set up that Dennis sells at Pantera Performance?
Where did you get your master cyls?

Yes, Dennis sells a tandem master cylinder setup that is manufactured by CNC. It is the same concept, but I wanted the features that I listed above in a modern approach.

Looks awesome, lots of engineering involved there!

Brooke, 4 days of CAD, 4 days of machining, a few days of debug. Another day to re-design and machine another the push-rod and add the brake switch. The original master cylinder failed on 5/24, I was back on the road 6/15. 2 pairs of master cylinders before I got the size correct. Excellent support from Tilton's Product Engineer Tim.

Jon, sorry for th late reply. Clutch Master is from Precision ProFormance. The version he "sells."

Dave, Your workmanship is excellent, I am considering the clutch master you are using over the CNC one I have. I think it's important to be able to see the fluid level.

Credit where credit is due...

Thank you Steve > Fountain Hills, AZ for his patience, experience and craftsmanship.
