Today doing a Dr Bike I encountered someone whose rear brake on their road bike was not working and he was confused as to why. On closer inspection there was something installed on the brake cable on the brake caliper. I asked what it was and he explained it was the sensor for a rear brake light, the rest of the system had been removed.
It was one of these devices.
I am not sure that it was designed for a caliper brake.

The stupidity was the way the sensor had been installed it stopped the brake actually working!
So it was now a device that lied, it told the person behind that his bike was stopping but it couldn't.
It made me think of this thread.
