Service Brake Lines:
Service brake lines are used to transmit compressed air from the air reservoir to the brake chambers of the vehicle. When the driver applies the brakes, the compressed air travels through these lines and actuates the brake chambers, causing the brakes to engage and slow down the vehicle.
Control Lines:
Control lines, on the other hand, are used to transmit control signals from the driver's controls (such as the brake pedal or air valve) to the various components of the air brake system. These signals are typically pneumatic or electrical and serve to regulate the flow of compressed air in the system.
In summary, while both service brake lines and control lines are part of an air brake system, they serve different functions. Service brake lines transmit compressed air to actuate the brakes, while control lines transmit control signals to regulate the operation of the brake system.
