BRAKE & FRONT END September 1963 In the 1950s and early 1960s, it was not uncommon for a driver to brake at the end of the long straights at Indianapolis. Engine technology was out pacing chassis technology and scrubbing speed was essential for making it through the corners. Also, in those days, cars came off turn four fast and ducked into the pits at speeds that would scare modern drivers. The hottest setup was disc brakes. Some of the systems were adapted from aircraft manufacturers like Lockheed and Goodyear. These systems soon found their way onto passenger cars.
