why bigger brakes are better if the limiting factor is the tyre’s friction coeficient with the road?

125 views

If you press hard on the brakes of a car, the ABS system will take over and control the stopping and rotation of the tire to insure the shortest stopping distance possible. How can a bigger brake calliper or disk influence the braking distance if the stock one is very capable of stopping the wheel?

Larger disks help to dissipate heat faster. Brakes overheating will fail or not work properly. In racing or track conditions, keeping brakes at proper temperature is important.

But you are correct in a sense. Larger disks and calipers tend to be more cosmetic than useful for a daily driver on the streets. The only legal driving situation where brake fade should come into play would be driving down very long curvy steep grades.
