I'm considering upgrading my master cylinder. I have installed the bigger BMW 320 Front Calipers and have Stock Calipers on the rear. I see from other threads that the 19mm master cylinder is a common upgrade, but what about 23mm. Automotion sells a 23mm as an upgrade, but it seem to me that it may to much for my application.

One of more often overlooked issues surrounding a change in the master, is the issue of pedal travel. Given no change in the piston diameter in the caliper, installing a larger master will allow for less pedal travel when exerting the same amount of downstream force. The brakes will definitely -feel- harder. However, the trade off is that with less pedal travel per unit of force applied, it will be that much harder to modulate braking force with your foot.
But, as Jake says about engines... "It's all about the combo". It's master/caliper/pad/tire all working in unison. Crappy tires (as Brett so wisely commented), will result in crappy braking. Same can be said about any other component in that path. -Josh2 |
