Need part numbers for C15A brakes

[Geoff Winnington-Ball (RIP)]

...when he first learned to drive, the way one stopped one's [auto]mobile was to stick one's feet out through the floor and drag them on the ground. To accelerate one began to run in place until said [auto]mobile began to move again.

He's really not much father ahead than that, so don't worry too much if you can't find what he thinks he "needs"...
