What are the three main components of the braking system?

The three main components of the braking system include service brakes, emergency brakes, and parking brakes.

Service brakes are the primary brakes used to slow down or stop the vehicle during normal operations. They are typically engaged with the brake pedal and are designed for consistent use in everyday driving conditions.

Emergency brakes, also known as emergency stopping systems or fail-safe mechanisms, provide a backup to the service brakes. They are crucial in situations where service brakes fail or when a sudden stop is necessary. Emergency brakes are usually manually operated and can be engaged independently of the main braking system.

Parking brakes are intended to keep the vehicle stationary when parked. They prevent the vehicle from rolling and are an essential safety feature, especially on slopes or uneven terrain. The parking brake is often engaged after the vehicle has been parked and ensures that the vehicle will remain stable until the driver is ready to drive again.

Understanding these three components is crucial for safe vehicle operation, as each plays a distinct role in the vehicle's overall braking capability.
