Boosterless Twin Master Cyl Brake Setup
Hey All,
As some people may know I like a lot of people am sticking a V8 in my track car. This has thrown up a fair few issues to overcome, one of which is brake booster and clutch master.
The booster is in the way of the drivers side bank and has to go, I've found a way around this but haven't got the know-wats to follow through with it.
On page 16 of the tilton catalog (linky: ) there are 2 different designs of remote master mount housing things, now either of these should fit and coming in at under $300 they are a lot less than the whole pedal boxes.
I'm leaning toward the 72-610 (side by side) but may need to got the 72-650 depending when they get back to me with some better diagrams.
Now the issue I'm having is matching the master cylinder size to the brake calipers, the front brakes are R33 GTS-T 4 pots and the rear are the 2 pots off the same car. dose any one know how to find the sizes to suit this setup?
I also need to find the bore for the clutch master from a supra (i figure as it using a supra clutch that it should be fine)
Cheers
Guys

10 char apparently
looking up the 33 bore size is nice and all but minus the booster it will bean that a fair bit of effort is needed to apply plus there are 2 master cylinders for the brakes, 1 front and 1 rear.
it uses a slave from a supra that i haven't confirmed a bore size as of yet.
Ah yes, forgot this.
Well, I have no real answer other then I would go for a SMALLER bore master cylinder if your running no booster. I found going smaller master for my hyrdo made it work better, (more pressure formed opposed to volume moved?).
whoops :/ forgot sorry
yea as said above something smaller, less movement so to speak but alot more force
as far as clutch goes if i get a clutch master the same bore as the slave was originally matched to that should be perfect right?
I heard 1 inch front, 0.7 rear, for a twin master set up. I'm running the same brakes, and mine will be around that mark.
yep should be
Cheap and easy... Freight from them is pretty good as well
