well, if you hold the brakes on when a car is wide open they will overheat and just fade. Try making 3 or 4 hard stops (not locking the tires up but just appling them hard from like 80kmh) and see how well they work on the third time compared to the first. Thats called brake fadding where the rotor and pads overheat and will emit a gas which will prevent the rotor and pad from making full contact with each other. This is why drilled and slotted rotors are so popular for racing use, the holes alow the gas to escape and the slots scrape off the overheated material. Anyways thats you lecture for tonight
