Why not fit a bigger bore master cylinder and have some much needed comfort room? Surely you can understand this would be better and safer?
Martin.
It's called compromise. There are several factors that have to be weighed when designing an apply system, and among them are comfort, seating location, pedal efforts and M/C operation.
Close to the floor is fine as long as you can fully stroke the master. Wear and fade won't change the total stroke available, as many OE vehicle's pedals will also be "close" to the floor during a full stroke check. Floor carpet doesn't have to be 1" thick to be comfortable, especially around the pedals.
Going to a larger M/C bore will increase pedal effort, without ratio change, and has to be considered. Keeping a manual system around 50 lbs. or less pedal force for most braking is a good target.
A few vehicles will allow a long brake pedal to stop well above the floor without looking or being awkward, but most will not.
