Working principle:

Mechanical braking relies on friction braking, calculated as in equation (1), and in some embodiments of the present application the brake pads 66 are made of a high coefficient of friction material to increase friction.

f＝μ＊Fn (1)

f frictional force

Mu sliding coefficient of friction

Fn positive pressure
