When it comes to safety, the smallest actions can have the biggest consequences—especially in cars. One such action that many drivers perform without thinking is pressing and holding the handbrake button when pulling the lever.
It might seem like a harmless habit, but in truth, this one mistake could put your vehicle—and more importantly, your life—at risk.
In this article, we will explain what the handbrake button does, why holding it down during use can be dangerous, and how to use the handbrake properly.
If you want to protect your transmission, prevent rollaways, and extend the life of your braking system, this is a habit worth breaking.
What Exactly Does the Handbrake Button Do?
The handbrake button—also known as the parking brake release button—is located at the end of the handbrake lever in most vehicles with a mechanical handbrake system.
When you pull up the lever, the rear brakes are engaged through a cable mechanism that locks the rear wheels, keeping your car stationary.
Pressing the button releases a ratchet-and-pawl locking mechanism, allowing the lever to move freely up or down without “clicking” into place.
The clicking sound you often hear when pulling the handbrake without pressing the button? That is the ratchet locking in place.
This lock is essential because it holds the tension on the brake cable, ensuring that the rear wheels remain locked. If this lock is bypassed—or released too early—the handbrake loses its ability to hold the car securely.
Why Holding Down the Button Is a Risky Habit
1. You Are Bypassing a Safety Lock
When you pull up the handbrake while pressing the button, you are essentially disabling the ratchet mechanism.
That means there is no locking resistance as you pull the lever, and once you release your grip, the lever could slip down if not held firmly.
If that happens and the lever drops just slightly, the tension on the brake cable might loosen enough for the car to roll.
Many drivers hold down the button to avoid the clicking sound, thinking it is more “polished” or “gentle” on the system. In reality, this behavior sacrifices safety for silence.
2. You Risk an Unsecured Vehicle on a Slope
On a slope or incline, even a momentary slip of the hand can cause a serious accident. Releasing the button prematurely or not setting the lever firmly means your car could start rolling backwards or forwards—especially if you are parked on a steep hill. Rear wheels lose their hold, and gravity does the rest.
3. You Can Accidentally Damage the Mechanism
Over time, avoiding the ratchet mechanism can lead to wear in unintended areas of the handbrake assembly.
This includes the release button itself, the spring tension inside the lever, or the pawl that is supposed to lock the handbrake into place. A worn-out handbrake mechanism means reduced reliability when you need it most.
How to Properly Engage the Handbrake
Using the handbrake correctly is not just good driving practice—it is fundamental to car safety. Here is how to do it the right way:
Step 1: Come to a Complete Stop
Always ensure the vehicle is completely still before applying the handbrake. Applying it while the vehicle is still slightly moving—even at crawling speed—can stress the brake cable and damage the system.
Step 2: Keep the Button Unpressed When Pulling Up
Pull the handbrake without pressing the release button. Let it click. Each click is the sound of the ratchet securing the brake cable into place. Pull it firmly until you feel resistance—typically 4 to 7 clicks depending on your vehicle.
Step 3: Do Not Rely on the Gear Alone
Some drivers park their vehicle in gear or ‘P’ (Park) without using the handbrake. This is a bad idea, especially on slopes.
In manual vehicles, this places stress on the gearbox. In automatic vehicles, it overworks the parking pawl inside the transmission. Always use the handbrake as your primary means of holding the vehicle.
Step 4: When Releasing, Press the Button
The only time you should press the handbrake button is when releasing the handbrake. With your foot on the brake pedal, press the button, then lower the lever gently.
Releasing it without pressing the button can wear out the ratchet teeth and damage the mechanism over time.
Does This Advice Apply to Electric Parking Brakes?
No. Vehicles with electric parking brakes operate via an electronic switch or button, and they do not use a ratchet-and-pawl system.
These systems automatically apply a specific amount of pressure to the rear brakes and lock them in place digitally.
However, just because electric parking brakes are “smarter” does not mean they are foolproof. Always wait for the dashboard confirmation before assuming the brake is set. If unsure, apply it again and listen for the motorized locking sound.
Common Misconceptions About the Handbrake Button
Let us clear up some myths:
- Myth: Holding the button prevents wear.
Fact: The ratchet system is designed to withstand thousands of uses. You are not doing the system a favor by silencing it. - Myth: The button must be held down to pull the lever up.
Fact: The ratchet works independently of the button. The lever is built to be pulled up without the button. - Myth: Only manual cars need the handbrake.
Fact: Every car, regardless of transmission type, should use the parking brake. Automatics can roll, too.
Handbrake Safety for Beginners and Learners
If you are teaching someone to drive, instill proper handbrake use early. Many bad driving habits—like coasting in neutral or riding the clutch—are hard to unlearn. The same goes for misusing the handbrake button.
Explain that the click is not a flaw but a feature. If they get used to silent application early on, they may develop a lifelong habit that puts their safety at risk.
When to Inspect Your Handbrake
Like any mechanical component, the handbrake can wear out over time. Here are a few signs your handbrake may need attention:
- The lever pulls up higher than normal (too many clicks)
- It fails to hold the vehicle on a slope
- You hear grinding or popping sounds when applying or releasing it
- The warning light stays on after disengaging
Have a certified technician inspect the cable tension, pawl condition, and lever integrity. A failing handbrake is not something to postpone.
Final Thoughts
The sound of a properly engaged handbrake might not be the most elegant thing in your car, but it is one of the most important.
By avoiding the handbrake button while pulling the lever, you are ensuring that the ratchet locks your rear wheels securely.
In rainy weather, on a steep hill, or even on a flat driveway, this simple step could be the difference between a parked car and a runaway one.
Take pride in driving well—and safely. Your vehicle, your passengers, and your peace of mind all depend on it.
