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

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?

Are better as they stay cooler. The colder it is the better it brakes. If a metal disc brake stays at low temperature, it means it will brake with the same force for the same pedal input. This allows you to have better control as you can predict the brake response. If you brake enough to trigger the abs, you don’t benefit from it, as you are not leading the vehicle, you are a passenger of your vehicle. For non professional drivers, it may give no benefit as the driver has no idea of what he is doing. For a better driver the better feeling of the brake is a big reward.

Rally drivers, which resembles as a sport what you would need to do on common roads, brakes are the primary mean to shift the car weight and balance your front and rear while making a turn. Now, unless you drive downhill on wet slippery roads for many minutes, trying to push your limit, a normal standard car with standard brakes will do its job regardless and stay cool enough regardless. If you actually push that limit, you would feel the difference between big brakes and small brakes. Again, it’s about control and feedback. It’s not about braking more. For braking more you are right, you need the brake power and tires to be of the same level. Improving only one won’t give results.

For carbon brakes, it doesn’t work like that. They get hot they brake better. So, brake quality is important there but with different technical solutions.
