Had a quiet spell in work so knocked up the infamous Bias Calculator in an excel spreadsheet, if you are like me, you can change the numbers to your hearts content and see what difference the various sizes make.

enjoy ! Angelo

Hate to say it but you are missing a lot of factors in there...

You need to add vehicle axle weights, disc diameter (effective pad working radius) to start with...

What you have got is only really useful for matching m/c size to caliper sizes (column E to be similar)

hi rich,

i'm sure it is very basic, i was just using one i found that i think Lanner had posted up on another brake thread, seemed to be what people were using as a guide. But if it is misleading I'll bin it.:o

Agreed, but at least he's got one part of the equation correct. In anycase, I have yet to see anyone spec such outlandishly different sized discs (rotors) that would make a noticeable difference. Also, we would then use a bias valve or balance bar set up to tune in the brake bias.
