Some geeky numbers about brakes
So I stumbled across some statistics about brakes on the internet, and remembering how much I was around when shopping for new brakes, I thought this might help some going in the right direction.
A general design rule-of-thumb for twin rotor brake systems is as follows:
30:1 - soft feel
27:1 - sweet spot for design
23:1 - firm feel
20:1 - wooden feel
You find the number by dividing the surface area of the pistons (calipers and M/C)
SP1 OEM calipers (34/32) = 6848,4 mm2
SP2 OEM calipers (32/30) = 6044,6 mm2
SP1 M/C (19mm) = 283,5 mm2
SP2 M/C (16mm) = 201,0 mm2
SP1 OEM = 24:1
SP2 OEM = 30:1
Not having tried a SP2, Im guessing the brakefeel should be a lot softer?
