I have seen a lot of posts regarding brake feel however my setup is a bit different than the articles I have seen. My car is mainly used for spirited street driving and occasional auto-x. Here is my current setup (all components are close to new):
-“wide-A” 911 front calipers -vented front and rear rotors -“vintage brakes” 914/6GT rear calipers -19mm master cylinder -ss brake lines -adjustable proportioning valve I realize my brakes are overkill for my needs. I have bled the brakes many times. My main question is- would a different master cylinder be of benefit? If so- larger or smaller? |

Larger MC = harder brake pedal, less pedal travel & less force at the caliper.
Smaller MC = softer brake pedal, more pedal travel & more force at the caliper. I’ve always liked the brakes on my bicycles to have that light soft spongy feel but to be powerful at the wheel. I found it easer to modulate and easer at the end of a long ride or race. We did the opposite at the shop for new bikes that people wanted to test ride in the parking lot. They wanted stiff quick moving brakes. |
