9 Times You Should Be Using Your Emergency Brake—and 3 Times You Shouldn’t
It was one of the first things you learned in driver's ed, so of course you know when to use your emergency brake… or do you?
Are you sure you’re using your emergency brake correctly?
Every car has an emergency brake—whether it’s a manual lever in the centre console, a foot brake on the floor near the pedals, or a modern electric push-button in the dashboard—but many drivers don’t know when they should be using it. Not really, anyway. So, what’s the story? The emergency brake was designed to hold, not stop, a vehicle, but using it can help you regain control of your car in extreme situations. There are other times you should be using your emergency brake, too, including a variety of parking situations. Here’s when you should be using this important safety feature—and when you shouldn’t.
Every single day
Applying the parking brake every day can take pressure off the transmission and other drive components, including the parking pawl, which locks up your transmission when you park but, of course, could always malfunction. According to Firestone, you should actually engage your emergency brake before shifting into Park “to limit the stress that’s put on your transmission, provide you with an extra layer of security, help prevent parking failure, and even prevent transmission repairs down the road. Think of the two systems like a dynamic duo—they’re better together!”

When your brakes fail
As its name implies, the emergency brake is there for emergencies. One of the most critical and frightening emergencies for a driver is when the brakes fail. In the event you are unable to stop your car, Nationwide Insurance suggests that you “slowly pull up on the emergency brake handle or press the pedal down to come to a complete stop.”

When parking on a hill
The classic and most obvious time to use your emergency brake is when you need to park your car on an incline. Whether you leave your car facing uphill or downhill, you will want to use the emergency brake to ensure you don’t find your vehicle at the bottom of the hill!

When parking on flat ground
Yes, you read that right. Numerous automotive experts say that you should use your emergency brake whenever you park your car, whether you’re on a hill or not. One reason for such frequent e-brake usage? “Emergency brakes that aren’t used can rust, which makes them less likely to work properly in an emergency,” according to Nationwide.

If you have a brake-fluid leak
According to Chaya M. Milchtein of MechanicShopFemme.com, “If you lose hydraulic power in your brakes (i.e., if you get a fluid leak), you can slowly apply your parking brake to help you get control of your vehicle.” Admittedly, this is not a perfect fix, says Milchtein, “as the parking brakes are intended to keep your car in one place and not stop a running car because they only engage the rear wheels.” But desperate times call for desperate measures, and this is one of those times—and something that can help you until you’re able to pull over safely.

While your car is getting serviced
“When your vehicle is being flat-bedded for service, you should apply the parking brake to remove the stress from the transmission,” says Lauren Fix, the Car Coach. Using the emergency brake when your car is getting serviced can also help keep the mechanics safe while your car is being loaded onto their truck. If your car needs a flatbed for service, it might be time to get a new ride.

When changing a flat tire
Fix also suggests using the emergency brake when changing a flat tire. This is an important safety precaution that will ensure the rear wheels don’t spin during the tire swap. This, along with blocking the tires with rocks or blocks, will keep the vehicle from rolling. Of course, it’s also essential for your safety to change a tire on flat ground, notes Edmunds.com.

When parking along a curb
The primary reasons to use your emergency brake all involve, in some way, a parking scenario. Richard Reina, Product Training Director at CARiD.com, adds parking along a curb to the list. “When parking along a curb in close quarters, use of the parking brake can help prevent transmission damage if your car gets nudged or bumped in its parking spot,” he explains. Plus, it can prevent your car from rolling if it gets hit.
When parking close to another car
If you’re parking anywhere near another car, use your emergency brake. “When you are parked close to somebody else, the emergency brake prevents the car from rolling,” explains Tommy of Vekhayn.com. “Because even if your car moves just an inch, it can cost you hundreds of your hard-earned dollars [if you cause damage to that nearby parked car].”

But don’t use your emergency brake during a snow or rain emergency
An emergency’s an emergency, right? Wrong. Anthony Diemedio, a service technician at Rafferty Subaru in Newtown Square, Pennsylvania, warns against using the emergency brake in a driving emergency that happens when it’s snowing or raining. “The rear wheels will lock up and you will lose more control and make things worse,” he explains.

When temps dip below freezing
While you’ll obviously need to use your emergency brake when it’s cold outside, you should be wary when the thermostat stays below freezing for a significant amount of time. According to How Stuff Works, “the emergency brake cable can become frozen and fail to release when the lever is disengaged.” If your emergency brake freezes up, don’t simply forge ahead and try to drive like that. Instead, wait for the brake to thaw or jack up the car and use a hairdryer to bring the temperature up.

When driving your car in normal circumstances
“Riding the brake” while driving causes friction on the brake pads against the rotors; that produces heat and makes the brake fluid boil. According to the Car Talk column in SF Gate, “Boiling brake fluid can’t transmit pressure to the brakes. So you may step on the pedal and the brakes don’t work!” While most drivers have accidentally left on the emergency brake at some point, it’s important to be vigilant and make sure your emergency brake isn’t engaged while driving. In fact, this is one of the ways you’re shortening the life of your car.
