Master Cylinder size
« on: January 14, 2009, 01:51:09 PM »
Is a cnc 3/4 master cylinder big enough for 4 wheel disk brake with single pistons on each?
Its better to be a smartass than a dumbass!

I believe it may be.

I use 5/8 bore masters on 2 front twin pistons.

 I can tell you that you will need a 7/8" bore to run two 4 piston wilwood calipers with 1.75 pistons!

Hi Punk, your question is very valid but im afraid its not as simple as that. There is much more we would need to know before anyone can give an opinion. Such as....

Diameter of pistons in master cylinder (hydraulic advantage)?

Diameter of disc (mechanical advantage)?

Ratio of brake pedal (again mechanical advantage)?

The simple answer is try it and see, thats what I would do, identifying a problem and then rectifying shouldnt be too much of an issue.

Some problems you may face are; good braking but excessive pedal travel, hard pedal, overly sensitive braking or damn perfect.

Good luck
