Hand Brake Valve Manufacturers

A hand brake, also known as an emergency brake or e-brake, is a mechanism used to slow or stop a vehicle in an emergency situation. The hand brake valve is the part of the hand brake system that controls the flow of brake fluid to the brakes. It is typically located in the center console of the vehicle, near the driver's seat, and is activated by pulling on a lever or pressing a button. When the hand brake valve is activated, it sends a signal to the brake system to apply the brakes. The hand brake is typically used in addition to the regular foot brake and is intended as a backup in case of failure or emergency.
The hand brake valve, also known as a parking brake valve, is a component in a vehicle's braking system that allows the driver to apply the brakes without using the foot pedal. The purpose of the hand brake valve is to prevent the vehicle from rolling when parked, or in emergency situations where the foot brake is unavailable.
The hand brake valve works by diverting air pressure from the foot brake to the brakes on the rear wheels. When the hand brake lever is pulled, it opens the valve and allows air to flow to the rear brakes, applying them and locking the wheels to keep the vehicle stationary. When the lever is released, the valve closes and the air pressure is redirected back to the foot brake system, allowing the vehicle to move. This principle is based on the use of compressed air in a pneumatic braking system.
To maintain the hand brake valve, you can follow these steps:
Check for leaks: Inspect the brake lines and connections for any signs of air leaks, such as hissing sounds or moist spots on the lines. If you find any leaks, repair them promptly.
Lubricate moving parts: Apply a light grease to the lever, cable and other moving parts to ensure smooth operation and prevent corrosion.
Adjust the cable tension: Over time, the cable tension may become loose, reducing the effectiveness of the hand brake. To adjust the tension, locate the cable adjustment mechanism and turn the adjuster until the hand brake lever has a firm feel.
Test the hand brake: Regularly check the hand brake by pulling it while the vehicle is parked on a level surface. The brake should hold the vehicle securely and release easily. If the brake fails to hold, or if it is difficult to release, adjust the cable tension or have it checked by a professional.
Replace worn parts: If you notice any signs of wear or damage to the hand brake valve or its components, replace them promptly to ensure the safety and reliability of your vehicle's braking system.
By following these steps, you can keep the hand brake valve in good working order and ensure that it functions correctly in case you need to use it.
