Ans - Trailer brakes provide additional stopping power and help maintain control while towing heavy loads. The operation of trailer brakes typically involves a hydraulic or electric system that activates when the towing vehicle's brakes are applied. Common brake parts include brake pads, rotors, calipers, brake lines, and brake controllers. It's essential to choose the appropriate brake system based on your trailer's weight and your towing vehicle's capabilities, ensuring safe and efficient braking performance.
