Hi,
On our F2 outfit we have a 0.625 (5/8") bore master cylinder feeding the front brakes (2 calipers) and a 0.7mm bore master cylinder feeding the back and side calipers.
Hope this will help

Hi Petercaughlin
It's not just a matter of Mastercylinder size, you have to take the rest of the system into consideration, lever ratios, number and type of calipers,etc.
As Whites knows as he baffled the living daylights out of everybody in his F2 thread !
But the bottom line is. . .the mastercylinder doesn't actually effect the braking efficency, only the 'feel'. so it's a matter of driver preference really.
That is unless you are trying to create some sort of 'bias' system, but that's not really the way to do it.
Big cylinders = hard pedal, less travel.
Small cylinders = softer pedal, more travel.
Hope this helps

I'm just about to list a 0.7 cylinder on the auction site....kezz32 wrote:I have just discovered that one of my master cylinders is well worn, weres best place to get ap 2623 short cylinders from guys ?
The only reason I'm not using it is the pushrod thread length is wrong for how I want to fit it - according to the AP Racing guidance - the pushrod's are matched to the cylinder - they will have them back to fit a different pushrod - but it would cost something like £40 - so if I can get decent money for it - I'll sell & buy a new cylinder with the correct length pushrod....
