RETRO: 1949 Crosley First Disc Brake Used Airplane Parts

In 1949, the tiny Crosley two-door weighed just 1,000 lbs, and the brakes were hydraulically actuated 6-inch discs. The brakes were adapted from a Goodyear-Hawley design and used off-the-shelf aviation parts. While this article from the April 1949 issue touts the advanced design and jet-age technology of the Crosley, after a year, the system was dropped for two reasons. First, the aircraft alloy parts had corrosion problems. Second, airplanes typically use the brakes only during takeoff and landing. Thus, constant use of the brakes caused the caliper mechanism to fail prematurely.

Benefits of Using Brake Parts Designed to Work Together

When replacing brake system components, it might seem like using compatible parts from any manufacturer – regardless of brand – should get the job done. However, for the safest brake job with the best performance, it’s always best to use parts from the same manufacturer, like ADVICS, where our brake pads, brake rotors, hydraulics, calipers
