【正文】 t until 1949 that disc brakes appeared on a production car though. The obscure American car builder Crosley made a vehicle called the Hotshot which used the more familiar brake rotor and calipers that we all know and love today. His original design was a bit crap though the brakes lasted less than a year each. Finally in 1954 Citro235。d cover these because they39。t) when you step on the brakes, the air bubbles press instead of the fluid transferring the motion to the brake calipers. Voila. Modern brake fade. So how do the engineers design brakes to reduce or eliminate brake fade? For older vehicles, you give that vapourised gas somewhere to go. For newer vehicles, you find some way to cool the rotors off more effectively. Either way you end up with crossdrilled or grooved brake rotors. While grooving the surface may reduce the specific heat capacity of the rotor, its effect is negligible in the grand scheme of things. However, under heavy braking once everything is hot and the resin is vapourising, the grooves give the gas somewhere to go, so the pad can continue to contact the rotor, allowing you to stop. The whole understanding of the conversion of energy is critical in understanding how and why brakes do what they do, and why they are designed the way they are.

The simple answer: they slow you down. The plex answer: brakes are designed to slow down your vehicle but probably not by the means that you think. The mon misconception is that brakes squeeze against a drum or disc, and the pressure of the squeezing action is what slows you down. This in fact is only part of the equation. Brakes are essentially a mechanism to change energy types. When you39。ve ever watched Formula 1 racing, you39。re about the most basic type of functioning brake that you can see, watch working, and unde
