Park brake lever/handle (hand brake)

The park brake lever, commonly known as the hand brake, is a crucial component in a vehicle’s braking system. It is typically located between the driver and passenger seats in a car, or sometimes as a foot pedal in some vehicles. The primary function of the park brake is to keep the vehicle stationary when parked, especially on an incline, and to serve as an emergency brake in case of a failure in the main braking system.

Basic Function

The park brake lever operates independently of the vehicle’s hydraulic brake system. When engaged, it mechanically applies the brakes on the rear wheels, preventing the vehicle from moving. This is achieved through a cable system that connects the lever to the brake mechanism at the wheels.

Operation

• Engaging the Park Brake: To engage the park brake, pull the lever upwards until you feel resistance and hear a clicking sound. This indicates that the brake is securely in place.
• Releasing the Park Brake: To release the park brake, press the button on the end of the lever and lower it back to its original position.

Maintenance

Regular maintenance of the park brake is essential to ensure its proper functioning. Here are some maintenance tips:

• Regular Inspection: Check the park brake lever and cables for wear and tear. Look for any signs of fraying or corrosion.
• Adjustment: Over time, the cables may stretch, requiring adjustment to maintain proper tension and effectiveness.
• Lubrication: Periodically lubricate the moving parts of the park brake system to prevent rust and ensure smooth operation.

Failure and Troubleshooting

Failure of the park brake can lead to dangerous situations, especially if the vehicle is parked on a slope. Common issues include:

• Loose or Stretched Cables: This can result in the brake not holding the vehicle securely. Adjust or replace the cables as needed.
• Corrosion: Rust can cause the cables or brake components to seize. Regular lubrication and inspection can prevent this.
• Worn Brake Pads or Shoes: If the brake pads or shoes are worn out, they may not provide sufficient friction to hold the vehicle. Replace them as necessary.

In case of any issues with the park brake, it is advisable to consult a professional mechanic to ensure safety and proper repair.
