How Does a Handbrake Work?
The handbrake, also known as the emergency brake or parking brake, typically controls the rear wheels of a car. At the same time, the foot brake is responsible for all four wheels (or just the front wheels in some cases). The main brakes are operated hydraulically, and the handbrake uses a mechanical connection to ensure it can serve as a backup if the primary brakes fail. Pulling the handbrake lever applies pressure to the rear brake pads or shoes, stopping the car independently. This functionality is crucial when driving on slopes or uneven terrain, providing an added layer of safety and control.
It’s designed not just for parking but also for emergencies or when starting on an incline, making it a vital component of your car’s braking system. Understanding how the handbrake in a car operates helps clarify its importance. Here's how it works:
- Cable Connection: A metal wire links the handbrake lever to the rear brakes, transferring the lever’s force with minimal power loss. Pulling the handbrake lever, the cable tightens, pressing the brake pads (for disc brakes) or brake shoes (for drum brakes) onto the discs or drums, halting the car's movement.
- Independent Rear Brakes: In modern vehicles, especially premium models, the rear axle has dedicated discs and brake pads for the handbrake. These components don’t connect to the primary braking system, improving holding strength and reliability.
- Electronic Parking Brake: Over the past few years, electronic parking brakes have become increasingly common. Instead of a mechanical cable, electric actuators are used to engage the brake pads. Pressing or pulling a button activates small motors that clamp the pads onto the discs, providing more convenience and precision.
How to Use a Handbrake in A Car?
Using a handbrake might seem simple, but doing it right makes all the difference for your safety and your car’s longevity. While the design varies between vehicles, a manual lever, an electronic switch, or an automatic system, the basic function remains to keep your car securely parked. In vehicles with a manual handbrake, you typically pull the lever up to engage it and push it down to release. With electronic or automatic parking brakes, it’s often just the push or pull of a button.
How to Use a Handbrake in An Automatic Car?
The correct technique for using a handbrake in an automatic car ensures better control, prevents unnecessary wear on the brakes, and, most importantly, keeps everyone safe.
When you're done parking
In automatic cars, the parking brake is designed to be simple and reliable. Here’s how to use it properly:
- Step 1: Press the foot brake firmly to bring the car to a complete stop.
- Step 2: While keeping your foot on the brake, shift the gear to "Park" (P). This locks the gearbox and prevents the car from rolling.
- Step 3: Locate the handbrake lever (usually between the front seats) and press the button on the end of the lever.
- Step 4: Pull the lever up firmly while pressing the button until you feel resistance. This means the rear brakes are engaged.
- Step 5: Release the button while holding the lever up, then double-check the parking brake light on the dashboard to confirm it’s engaged.
- Step 6: Once the parking brake is fully applied, gently lift your foot off the brake pedal.
When you're ready to go
When you’re ready to drive an automatic car, here’s how to properly release the parking brake:
- Step 1: Press and hold the brake pedal firmly before starting the car or moving the gear lever.
- Step 2: Shift the gear from "Park" (P) to "Drive" (D).
- Step 3: Locate the parking brake lever and press the button at its end.
- Step 4: While holding the button, gently lower the lever to release the parking brake.
- Step 5: Check the dashboard to ensure the parking brake light has turned off.
- Step 6: Slowly release the brake pedal, then press the accelerator to drive forward smoothly.
Note: The process is even simpler if your automatic car has an electric parking brake. Press or pull the button marked with a "P" to engage or release the brake. The system’s electric motors automatically apply or release the rear brakes without manual effort.
How to Use a Handbrake in A Manual Car?
How you use the handbrake also depends on your car’s transmission type. Parking or starting on a slope in a manual car requires a different approach than an automatic.
When you're done parking
Using the handbrake in a manual car, especially on slopes, needs a little extra attention. Here’s how to do it right:
- When parking on a flat surface: Shift the gear lever to neutral and pull up the handbrake. This keeps the car still without putting extra strain on the gearbox.
- When parking on an uphill slope: Shift the car into first gear, then pull the handbrake up firmly until it locks. First gear helps prevent the vehicle from rolling backwards.
- When parking on a downhill slope: Put the car in reverse gear before applying the handbrake. This helps hold the car in place and stops it from rolling forward.
When you're ready to drive
When you’re ready to drive a manual car, follow these steps for a smooth start:
- Step 1: Press the clutch and brake pedals to stop the car completely.
- Step 2: To release the handbrake, gently lift the lever slightly, press the button at the end, and lower the lever fully.
- Step 3: Shift into first gear and slowly start lifting your foot off the clutch while gently pressing the accelerator.
- Step 4: On an uphill, use the handbrake to prevent the car from rolling backwards.
- Step 5: Find the "biting point" where you’ll feel the car wanting to move forward as you slowly release the clutch.
- Step 6: Rev the engine slightly to the ideal RPM, then release the handbrake. The car should move forward smoothly without rolling back.
Mastering the handbrake in a manual car gives the driver greater control in challenging situations, enhancing both safety and driving experience. This skill is especially valuable in stop-and-go traffic or when navigating uphill and downhill.
