What Part Does the Handbrake Act On?

[DiLucille]

Handbrake acts on the rear wheels. Also known as an auxiliary brake, it operates differently from the main braking system by using a steel cable connected to the rear brake to stop the vehicle. Prolonged use of the handbrake can cause plastic deformation of the cable, which is irreversible and gradually reduces effectiveness while increasing the handbrake's travel distance. When using it, ensure the vehicle is stationary, then pull the handbrake upward to engage the parking brake. The handbrake system also includes a return spring - stretching when engaged and retracting when released. Extended usage may also cause deformation in this spring.

When I first started learning to drive, I was also curious about which wheels the handbrake actually stops. Later, I learned that it mainly engages the rear wheel braking system. To be more specific, when you pull the handbrake lever, it activates a steel cable that pulls the rear brake pads or shoes, pressing them against the brake discs or drums to create friction and prevent the wheels from rotating, thus keeping the car stationary. I drive a manual transmission car, so every time I park, I have to press the clutch, shift to neutral, and then pull the handbrake. If I'm on a slope, I need to first stop the car with the foot brake and then firmly engage the handbrake to prevent rolling. I remember one time when I forgot to pull it, and the car slowly rolled backward, almost hitting a wall—it was quite a scare. Beginners should make it a habit to check if the handbrake is fully engaged. During regular maintenance, it's also important to have the mechanic inspect the cable for wear to avoid failure and added risks. Essentially, its core function is to lock the rear wheels to ensure parking safety, separate from the foot brake used during normal driving.

Years in the auto repair business have taught me that the handbrake serves a straightforward purpose: it specifically engages the braking components on the rear wheels. Its internal mechanism connects via levers and cables to the rear wheel brake shoes or disc brakes, creating friction to halt wheel rotation when engaged. Unlike the foot brake, which uses a hydraulic system for comprehensive control, the handbrake is mechanical, offering greater reliability and longevity. In practical use, be mindful that cables may wear out or rust, leading to failure—common in older vehicles. I recommend an annual inspection of the braking system, especially after the rainy season to prevent rust. New drivers should avoid engaging the handbrake while moving, as it can damage the drivetrain or cause skidding. Modern electronic handbrakes still physically lock the rear wheels, operating on a similar principle but with more user-friendly controls. Veteran drivers might miss the mechanical feel, but the safety performance remains identical.

We veteran drivers pay great attention to details. The handbrake specifically controls the rear wheel braking – simple yet practical. Older models used manual levers, while many modern cars feature button-controlled electronic systems, but fundamentally they all serve to lock the rear wheels and prevent rolling. I always emphasize this parking routine: engage the gear and apply the handbrake for double security. On slopes, press the foot brake first before firmly pulling the handbrake. I've witnessed careless cases where vehicles rolled away and crashed – how dangerous! Regular brake pad replacements ensure long-term effectiveness.
