Larger bore brake master cylinder

[gofastgeorge]

OK, I found a picture of a 1-1/16" bore brake master cylinder in Japan,
that a guy was selling for a Mk3 Supra/Soarer.
Being in Japan, it was made out of Unobtainium.

Now, I can not find out what car this was possibly from.
Everything I am finding is 3/4" or 7/8".
Do any of you hard core Supra guys know
what that master cylinder was out of ??

I believe DrJonez, a member here, took the stock one and drilled it out. That's all. I'm sure he'll post up if he looks at this thread.

George: Why do you want to go larger?

i was going to put a spare one in my work van.i'm under car and truck hood's all day,maybe match it up with something.i'd like to have a direct bolt up with little to no modifing

I would look at Toyota 4x4s, and Hino vans.

You guys do realise a larger bore Master will require MORE pedal pressure don't you?

 

[annoyingrob]

lol. Right. Mechanical advantage works the other way doesn't it. Maybe we just want less pedal movement.......

6-piston Wilwoods.
I am concerned about peddle travel after I put the big calipers on.

I ran my TTV8 240z without boosters so had to learn all about sizing

bigger = more pedal effort/less pressure/shorter stroke

smaller = less ledal effort/more pressure/longer stroke

In my case I could change pivot points and MC bores to get the exact result/feel I wanted/needed and it worked perfectly.

George: All depends on the piston sizing in the calipers.
