Is the Parking Brake Lever the Handbrake?
3 Answers
Parking brake lever, commonly referred to as the handbrake, functions to provide resistance to the vehicle when parked, preventing it from rolling. The parking brake, also known as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. The force applied by the parking brake is much smaller compared to the service brake, sufficient only to prevent the vehicle from rolling on slopes. Below are introductions to disc brakes and drum brakes: Disc Brakes: Disc brakes, also known as rotor brakes, are named for their shape. They are hydraulically controlled and primarily consist of components such as the brake disc, wheel cylinder, brake caliper, and brake lines. The brake disc, made of alloy steel, is fixed to the wheel and rotates with it. The wheel cylinder is mounted on the stationary base of the brake assembly. Drum Brakes: A typical drum brake mainly consists of components such as the backing plate, brake drum, brake shoe, wheel cylinder (brake cylinder), return spring, and locating pin.
That's right, the parking brake lever is what we commonly call the handbrake! I've been driving for over 20 years, and veteran drivers all refer to it that way. This thing is particularly common in traditional fuel-powered vehicles, usually standing upright on the right side of the driver's seat—pull it up, and it locks the rear wheels. Don't underestimate this little lever; it's what prevents your car from rolling at red lights or on slopes. However, many new cars now come with an electronic button instead, tucked near the dashboard. The principle is the same, except instead of manually pulling a cable, an electric motor does the work for you. New drivers should practice getting a feel for it in an empty space first—pulling too hard can cause wear, while not pulling tight enough is dangerous.
To put it simply, the parking brake lever is the official name for what we commonly call the handbrake. In the auto repair world, we usually refer to it as the parking brake lever. It operates by using the principle of leverage to pull a steel cable, which then locks the rear brake pads. Nowadays, some cars have done away with the physical lever, but the function has been carried over to electronic parking brakes. I remember one time a customer complained about the lever sticking; when we took it apart, we found that a spilled soda from the cup holder had seeped in, and the sugar had gummed up the mechanism. So, it's best to engage the handbrake firmly and decisively—you should hear about six or seven 'clicks' for it to be properly set. If you see a red circle with an exclamation mark lit up on the dashboard, chances are the parking brake isn't fully released.
