•Your foot pushes on the brake pedal.

•The piston pushes the brake pad (green) toward the brake disc (grey).

•The break pedal pushes a piston (blue) into a master cylinder filled with hydraulic brake fluid (red).•The brake fluid squirts down a long, thin pipe until it reaches the slave cylinder at the wheel.•When the fluid enters the cylinder, it pushes the piston in the wider cylinder (blue) with an increased force.

•When the brake pad touches the brake disc, friction between the two generates heat.•The friction slows down the outer wheel and tyre, stopping the car.

•Air brake systems are bulky, and require air compressors and reservoir tanks.

•Air brakes, where a valve is opened and air flows into the lines and brake chambers until the pressure rises sufficiently.

•Compression problems with air brakes can cause delays in braking performance.

•Air Brakes have a longer stopping distance.

•Hydraulic systems are smaller and less expensive.

•Hydraulic systems rely on a single stroke of a piston to force fluid through the system.

•With innovations like anti-lock brake systems, traction control, and electronic stability control, hydraulic brakes have become safe.

•Vehicles with hydraulic brakes have shorter stopping which arguably makes them a safer product.
