Thanks guys. I’ll go over those sums Stefan! I did actually include the coefficient and pad numbers in my attempt. Coefficient I used 0.5, 2 pads, and disc rad at 0.08 then rounded it all up to 0.1. I have no idea what the pad coef is.
You guys don’t spend very long braking do you! I think you are all underestimating the actual time spent braking. However, variations in these parameters don’t affect the end result a great deal. ( no wonder I’m always at the back! ).
You’re right about bent legs/ leg pressure etc. Probably best to err on the low side for foot pressure on the pedal.
When I was measuring the pedal ratio, David noticed that it was easy to reach the bulkhead with the pedal under full braking pressure. I suppose it’s possible that during those ‘poor braking moments’ my pedal was actually hard up against the bulkhead and no additional pressure was being created, hence reduced clamping force and therefore no brakes. Probably a more realistic cause than fade, as your sums show.
So what do we think a realistic foot pressure might be?
