The parking brake, also known as the emergency brake or handbrake, is a secondary braking system designed to hold a parked vehicle in place and provide an extra safety margin in emergency situations. While it is often overlooked in daily driving, using the parking brake correctly can reduce transmission wear, protect your vehicle’s rolling stability on slopes, and serve as a reliable fail-safe if the primary braking system fails. This article explains when to use the parking brake, how to apply it properly for different transmissions, and common myths and maintenance tips to maximize safety and longevity.
When To Use The Parking Brake
Use the parking brake whenever you park on an incline, on level ground when you want an extra hold, and during long-term parking to minimize load on the transmission. On steep hills, activating the parking brake before shifting into gear helps prevent the car from rolling as the driver moves from the brake pedal to the seat or door. In cold or slippery conditions, the parking brake adds a redundant hold to reduce the chance of creeping or rolling after you stop. For manual transmission vehicles, the parking brake is especially helpful in keeping the car stationary while starting on an incline.
How To Use It Correctly
Automatic Transmissions
Stop the vehicle completely, apply the regular foot brake, and then engage the parking brake. If the vehicle is on an incline, keep your foot on the brake until you feel the car secure, then shift to Park. In most cases, you should avoid releasing the foot brake until the parking brake is fully engaged to prevent a sudden lurch. When leaving the car, ensure the parking brake is fully set and the transmission is in Park before exiting.
Manual Transmissions
With a manual transmission, come to a complete stop with the clutch engaged. Shift into first gear or reverse, then apply the parking brake. In some situations, especially on very steep hills, you can use the parking brake in combination with the clutch to prevent rollback while releasing the handbrake and engaging the appropriate gear. Always release the parking brake gradually once the vehicle is ready to move to avoid a sudden shift in balance.
Parking Brakes On Hills And Slopes
On hills, the parking brake acts as a critical fail-safe to prevent unintended movement if the primary braking system fails or is compromised. Start on a hill by applying the foot brake, set the parking brake, then release the foot brake to test that the car remains stationary. When leaving, ensure the vehicle remains secure by keeping the parking brake engaged until you are ready to move. For manual transmissions, using the parking brake can help mitigate rollback when starting on an incline, reducing strain on the engine and transmission.
Common Myths And Misconceptions
Myth: Parking brakes are only for emergencies. Reality: They provide an essential hold when parked and add redundancy to the braking system. Myth: You should use the parking brake all the time while driving. Reality: It is not designed to replace the foot brake during normal driving and can wear the system if used improperly. Myth: If the car rolls when parked, the parking brake failed. Reality: It can fail due to wear, improper adjustment, or ice; regular inspection and maintenance are necessary to ensure reliability.
Maintenance And Safety Considerations
Regular inspection of the parking brake cables, shoes, or pads is essential. Look for signs of wear, fraying, uneven tension, or sluggish engagement. If the parking brake feels weak, drags, or does not hold on a known incline, have it inspected by a qualified technician. In colder climates, ice can hinder parking brake performance; use extra caution and avoid relying solely on the parking brake in severe conditions. Do not rely on the parking brake as a substitute for the primary braking system when driving; it is a safety backup, not a primary method of stopping.
Emergency Use And Quick Reference
In an emergency where the primary braking system fails, immediately engage the parking brake to buy time and slow the vehicle. If possible, steer to a safe area and alert others while gradually reducing speed. After stopping, keep the parking brake engaged while you assess the situation and call for assistance. Remember to have the brake system inspected as soon as possible after an emergency use.
