And Jaguar was so worried that they put a little metal emblem on the rear bumper with a red triangle to warn drivers behind.
Not quite, back in the days of vintage motoring (we're talking just after the retirement of the red flag man here) there were cars with some pretty terrible brakes on the road and you didn't know how well a car might stop. There were many advances in brakes in a short time from cable and pushrod operated axle brakes to fully hydraulic wheel brakes and these triangle badges were used to show what kind of braking the car ahead might have. I've seen them labelled '2 wheel brakes', '4 wheel brakes' and 'hydraulic brakes'. I've never seen one labelled 'disc brakes'. I don't think they were a legal requirement but were commonly used just to show when a car had a new type of braking. Maybe they were used to show the advent of disc brakes but I'd have thought the badges were a lot older than that to be honest.
I don't think that's quite right about the Mk2 Jag being the first use of disc brakes but I can't remember what else might have used them.
