Abstract
A brake performance monitor has a first sensor 12 for detecting movement of a brake device to apply the brake, and a second sensor 14 for detecting a predetermined force necessary to apply the brake in normal operating conditions. If the braking force deteriorates, the brake movement is detected before the predetermined force is reached, and an output device 10 signals the fault, for example by halting the machinery 4 being braked.
