Hello folks,
Quick question about how OEM brake bias is set up on cars. I understand that old cars used to have the ‘proportioning valve’ that would help control the HYDRAULIC brake bias (which nowadays is replaced by EBD), but I would like to know the actual brake bias as in how much more front bias would a large 6 piston caliper have over a small 4 or 2 piston caliper. I understand that brake bias hydraulically generally stays the same (unless EBD/ABS is enabled, meaning 50/50 until a wheel locks up) but what I’m asking is basically how would you calculate a car’s true brake bias using caliper size and piston width, etc?
Thanks!
