Principles of braking
|
Friction between braking surfaces converts kinetic energy into heat. In drum brakes, wheel cylinders force brake linings against the inside of the drum. In disc brakes, pads are forced against a brake disc.
|
Drum & disc brakes
|
Drum brakes have a brake shoe that expands against the inside of a drum; disc brakes clamp a flat disc between two pads; an antilock braking system is a control system that applies maximum braking force without wheel-lock or skidding.
|
Coefficient of friction
|
The coefficient of friction is the measurement of friction between pairs of surfaces.
|
Lever/mechanical advantage
|
Mechanical advantage (MA) is the factor by which a machine multiplies the force put into it.
|
Hydraulic pressure & force
|
Hydraulic pressure is transmitted through liquid & can transmit increased force.
|
Brake fade
|
Fade, or brake fade is the reduction in stopping power caused by a buildup of heat in the braking surfaces (and in the case of drum brakes the change in dimension of components in response to heat).
|
| Regenerative braking |
Regenerative braking is any technology that allows a vehicle to recapture and store part of the kinetic energy that would ordinarily be lost when braking. |
