Big Reds installed, but now what master cylinder to use?

[70Ghia]

And I used the non-turbo m/c

do you think i'll be ok with stock for now, cause i have a show coming up very soon, and the car still has to get painted.....

[BuG60]

Sorry, BuG60 and VRSICK are the same people, me....

On my laptop it uses my old name.
Question remains though, the stock MC is installed right now, and I think i'm gonnah have to stay with it, atleast until after it gets painted, and after my first car show coming up in july. But after that, I will NEED to replace it with something else.

PS, MBT.de doesn't have anything there....

It's not pressure you need to worry about, it's f/r bias (of pressure) and fluid volume displacement that needs looking at. The pressure is simply proportionate to applied pedal effort.

The stock m/c works* with most 'big' calipers because the orignial drum brakes have no self-adjustment to compensate for wear. They rely on the long stroke of the m/c.

You will be able to tell if your m/c is big enough if you bleed the air out by the pedal method.


* 'works' in terms of volume but not necessarily in bias

The sure way to know if your system works as a system is to have them tested on a plate brake tester, just drive on, hit the brakes and let strain-guage technology interpret the reaction of the road.

I'd be looking at the m/c off a T2 before that off a 944
