As a teen, I was wheeling an inherited 1950 Windsor when a car Hollywooded a stop sign and appeared directly in front of me. With lightning-quick teen response, I crushed the brake pedal, felt I was good and then felt the pedal go to the floor as a maybe15-year-old brake hose ruptured. Again, quick, because there was no "Dodge-ing" him, I yanked the parking brake which locked up the back of the Flush-o-Matic tranny and rear tires without breaking any U-joints. Close one. Disc brakes are no substitute for defensive driving. I figured the reason the brake pedal on our C-300 was so there would be room for both feet. Happy Mother's Day out there.

A little story behind that... About 20 years ago I was driving my daily driver, a 1947 Desoto Suburban with a 139.5-inch wheelbase, down a San Francisco Bay Area Freeway at 65 MPH. Coming close to a place called the Caldecott Tunnel a guy in a car cut me off and then stopped dead. With drum brakes I know I could not stop and I also knew that if I tried I was likely to fight the steering to keep it straight. I had to crank over on the steering to the right hoping my peripheral vision was correct that nobody was next to me. When I made that maneuver to miss the idiot, I was now heading to the tunnel entrance wall. I had to swing the steering back straight and all the while I was sure the thing was going to snap and roll. I figured I was dead. The front of the Desoto tried to lurch over, but it did not. It felt like the very long wheelbase held it back as the car twisted in the middle. I got the car to settle down and through the long tunnel. When I popped out the other side a guy cam up next to me in an SUV and rolled his window down and yelled at me that that was great driving. He saw the entire episode. I yelled back that I needed to change my underwear. The next week I started on a front disc brake set up for that car so that a high-speed panic stop would at least have some decent directional control. Particularly for such a tall center of gravity car. Doing that conversion, I learned all about "modern" brake systems and their components.
