(2) Larger piston in your caliper means your piston moves more slowly for a given amount of fluid. It is only the piston moving forward against the pads which causes the car to stop. Now you must move the brake-pedal/master-cylinder farther to accomplish this, thus you are spreading the same amount of force (moving piston towards pad) as before over a longer master-cylinder stroke, which results in a lighter pedal feel, which begats greater pedal feedback/sensitivity. This reduces the former mushy/"dead" pedal feeling, instead returning a sensation of responsive, fine, direct control.
I assume you ment to say "moves less for a given amount of fluid" speed of movement is dependant on the speed you press the pedal. in this instance it will take approx 16% more pedal movement to move the pads by the same amount when compared to the standard brakes.
The amount of actual pedal movement is also dependant on other factors like how flexable the caliper is and how far off the disc the pads run when the brakes are off.
Also the increase in brake force at the contact patch, the bit where the tyre meets the road, is around 35% more for the same line pressure hence the lighter pedal and more feel with these calipers and discs.
Nitroman, what was your previous post about, do you need a new cotter pin? or are you after the bits to fit this conversion?
