1500 fnt discs & 944 rear discs

[Shad Laws]

Hello-

cheers again
it looks like im gonna have to run a proportining valve then in order to run the setup i can afford

Sounds good!

just out of curiosity i tried to work out the braking bias on a stock bug, i got 3:1 now surely this has got to be way off??
bug drum rear cylinders are stock 19mm cyls and front disks at 40mm, what you make of this shad?? is it a different calculation for drums???

The physics is the same, but the parts we could previously neglect can no longer be neglected...

When you have two disc brake setups with similarly-sized rotors, similar pad materials, similar heat/water/etc. problems, and similar wheel speed (i.e. not a 30" rear wheel and a 10" front one :-), then you can just think about the area ratios. But, when you change one of these substantially, you can no longer neglect the effects of these things.

Drum brakes have a LOT of very big differences compared to discs, so the simple approximations used above are no longer very good approximations.

Take care,
