Should use them to re-confirm the Peugeot brothers' brake testing.
Run them down a hill, and get someone to jam a broomstick into the rotating wheel to work out whether it's better to stop the front or the back wheel.
When I was 18, I had my favourite hill to ride my "Super Elliot Special 10". I could go faster than the Porsches in the area, requiring heavy braking (I did have dimpled Aluminum rims) before a "T" intersection at the bottom.
One day I replaced the brake pads with brand new $2 (K-Mart) pads.
Tore down the hill, and bedded the brakes in using a manner that the Critic would be proud of.
The rubber peeled off the pads, and I was left with squat, with an 18 wheeler with right of way.
Made it...just.
Calling "No Brakes" may have worked equally as well.
