How to Brake and Stop a Car in the Shortest Distance
Braking and Stopping a Car with ABS
Press down the brake firmly and smoothly.If you push your foot down on the pedal in a car with ABS, you will feel the brake pulsating under your foot, sometimes violently. Don't be afraid of this or let go -- that just means the brakes are doing their job. Depress your brake pedal with rapidly, but not instantly. This is essential to maximize the braking potential of your car. The goal is to bring the vehicle's tires just shy of breaking traction. It is important, though, to avoid "squeezing" down on the brakes if your car has ABS.
- The key is to apply the brakes quickly and deeply, while applying pressure with the left foot against the footrest to stabilize the body.
- As the car's speed is being scrubbed off, you can progressively and gently ease off of the brakes to keep them at the point of maximal efficiency.
Don't brake and swerve the car at the same time.Gentle turning while braking can help you avoid a collision. However, don't ever swerve or jerk the steering wheel, as this can cause the vehicle to go out of control. It is not uncommon for people to swerve to miss a small animal and end up colliding with a tree or another car. In some circumstances, such as if a child jumps in front of your car, it is prudent to turn while you apply your brakes. You should practice this in a safe environment so you'll get an idea of how the vehicle will react. Here are some different ways to brake your car:
- Brake-turning.Turning the wheel into the corner while still lightly on the brakes. This causes the car to lean forward, pressing the front tires to the ground, giving them more grip for steering. This a basic technique, and no corner should be made without it.
- Trail braking.This is a method of feathering the brakes while turning into the corner and it will provide the best and safest control over the vehicle as it is leaning on the front tires, allowing for more traction to those tires.
- An emergency stop.If a need to stop quickly is due, you should not fear using the brakes, even mid-corner: With ABS, depress the pedal all the way down. Without ABS, brake moderately hard (70%) while taking off a bit of steering.
Avoid using your transmission for quick stops.The transmission is design to accelerate the vehicle not slow it down. The design of the load points on the transmission gears are not designed for this. It is not a component of the braking system. If you operate a tractor trailer, it is a different story. They are equipped with air brakes and engine brake for a reason that is irrelevant for cars. However, it is a good practice to use engine braking for maintaining or decreasing speed on long downhill stretches.
- The heat generated is absorbed by the engine and removed efficiently by its coolant, radiator, and fan, which prevents the brakes from overheating so they will be most effective when needed for maximum braking.
Focus on where you want to go, not what you want to avoid.It's very difficult to steerawayfrom something that you're looking at directly, and many people have a tendency to focus on what they are worried about colliding with. Instead, concentrate on where you want the car to go (to the side of the object) and pay attention to how the car feels—whether you're at OSP or locking up.
Braking and and Stopping a Car without ABS
"Squeeze" the brakes.If your car does not have ABS, then you shouldn't hit or slam the brakes. Instead, you should squeeze the brake pedal firmly with your foot to stop the car as quickly as possible. You should squeeze the pedal down until right before the tires begin to skid, which will reach the limit of the traction of the tires. If you push down on the pedal too hard, you will lock the brakes and will lose control of your vehicle.
Brake at the limit before the brakes lock up.This is called "threshold braking" and will make your car stop as quickly as possible. Listen for a faint howl from the tires, which will tell you that you haven't reached the limit and that you're doing the right thing. If the wheel locks up and you've lost control of the car, then you've gone too far and have to let go and reapply the brakes again.
Don't look at the object that you are colliding with.Look to either side of the object and try to aim the car away from it instead of colliding with the object head on. If you're mesmerized by the object that you're about to hit, then you won't be able to focus on threshold braking, which will require your full concentration.
Press your left foot against the floor.Pressing your left foot against the rest pad area will help you brace your body against the damage and will make you for sensitive to knowing how you should modulate the brake pedal.
Practice threshold braking.It takes time and practice to master this type of braking, and spending some time doing it in an empty parking lot can improve your chances of success if the time ever comes. Also, practicing squeezing the brakes both firmly and lightly in your everyday driving can help you improve your braking skills -- and can save your life when the time comes.
- You can measure this by setting up markers as to when to start braking and when you stop the car, and you can visually see the difference between your tires locked up and not.
- Extra practice: Purposely lock up your brakes. Now practice reducing pressure on the pedal until it stops locking up, then apply pressure again to the OSP (optimal squeeze point) again. Inevitably, you will go over your OSP, or you will change surfaces while braking, that is why this practice is essential.
- Take note: each surface and speed will have different OSPs. This is why you should practice while it is dry, then while it is raining, and then when it is snowy, if it's possible.
QuestionHow much distance is needed to stop safely if a car is traveling at 100 km per hour?wikiHow ContributorCommunity AnswerIt depends on the car and the condition of the brake pads, brake calipers, brake fluid pressure, tires, suspension, and brake rotors (these will change if the car has drum brakes).Thanks!
QuestionIs it necessary to push the clutch while using the brake to stop the car? Or when you are using 3-4 gear in hills while going uphill?Top AnswererYou need to push the clutch in to change gears but when needing to brake in an emergency, don't push it even if the car stalls.Thanks!
QuestionCan I stop with my brakes without pressing the clutch?wikiHow ContributorCommunity AnswerUnless you're driving in neutral, you have to press the clutch or else the engine is going to stall when you slow down.Thanks!
QuestionWhen driving and coming to a stop sign, do I press both the clutch and brake at the same time before driving off?wikiHow ContributorCommunity AnswerJust press your brake to reduce the speed of your car, and when it is about to stop, press on the clutch so as not to stall.Thanks!
QuestionCan I use clutch and brake together?Top AnswererJust brake without clutching, as the engine will help slow down the car.Thanks!
QuestionWhen do I use the handbrake?wikiHow ContributorCommunity AnswerYou can use the handbrake to do a handbrake turn or a power slide but usually, just use it to park the car. The handbrake will lock the rear wheels, so you can leave the car just still and make sure it goes nowhere. Be sure to put it on before releasing the foot brake so that the car doesn't jump or roll forward when on a slope or in a car park.Thanks!
QuestionWhat is the safest way to brake?wikiHow ContributorCommunity AnswerThe safest way to brake is to gently push your brake pedal until your car makes a complete stop. In emergency cases, press it rapidly while also possibly turning the steering wheel. In extreme cases, you can even use the hand brake to direct your path away from the object of collision, but you should have an idea as to when you should let go of the hand brake to avoid the car from stalling.Thanks!
QuestionHow do I drive a manual motor vehicle?wikiHow ContributorCommunity AnswerBefore you start, you should adjust your seat and the mirrors. Once you have done that, you put your left foot on the clutch (the pedal on the very left) and your right foot on the brake (the pedal in the middle). You can now insert the key and turn it to start the engine. Disengage the parking brake and shift into first gear. Release the brake pedal. Now, you must slowly release the clutch (if you do it too fast, you will kill the engine).Thanks!
QuestionDo I brake with the left or right foot?wikiHow ContributorCommunity AnswerAlways the right foot for braking and accelerating. The left foot is only used for the clutch pedal.Thanks!
QuestionWhat can cause the emergency brake to cut off the engine?wikiHow ContributorCommunity AnswerIf your car gets too slow, the engine's rotation speed is too low for it to function properly, which can cause the engine to die.Thanks!
If your car has anti-lock brakes, or ABS, stop your car by pressing down on the brake pedal firmly but smoothly. If your car does not have ABS, squeeze your brakes to the point right before they lock up. Practice in an empty parking lot so you can get a sense of when they lock up. Regardless of your brakes, do not jerk the wheel while braking to avoid a collision. Instead, focus on where you would like the car to go and steer that direction while applying gentle pressure to the brakes.
- If your rear brakes are stronger than your front, stop driving the car. Although a perfectly balanced front/rear bias will stop the car the quickest, all car manufactures engineer with front bias. A bit of front bias is the safest condition. If your rears keep locking up first, then something is wrong. Stop driving the car. It needs to be inspected by some competent in diagnosing and repairing brake systems. The repair may be as simple as using a more aggressive pad compound in the front or less aggressive pad compound in the rear. If your rear brakes lockup, back off the brakes until they are no longer locking. Braking with rear brakes locked will likely result in a spin.
- If you experience poor front-to-back balance during a situation where you cannot check/change/clean them: if the front brakes are stronger than the rear, brake normally (while you will stop slower than with balanced brakes, this is still your best option).
- Some times a good cleaning is all they need. The easiest way to clean them is to accelerate to highway speeds (65-70MPH) (in a safe area) and stop very quickly (do not lock up the brakes).
- Practice in a safe location. Keeping you, your car, and others in the area safe is worth more than all the skills you think you have.
- You want to hear a little bit of squealing when braking hard. This lets you know you are at the limit of your traction.
- On a vehicle which the brakes are out of balance (the rear brakes are much stronger than the front or vice versa), be sure to check brake pads and rotors and replace them if necessary.
- On low traction surfaces (loose gravel, snow, or ice) no squealing will be heard, and the OSP is more difficult to achieve. It is safer to keep traction and not push too hard (this also keeps your ability to steer).
- On a vehicle which the brakes are out of balance (the left side brakes harder than the right or vice versa), enough traction must be kept to allow for the correction in vehicle direction.
- Try applying the hand brake a little bit to reduce the stopping distance. Do not apply them too hard. Start lightly and keep increasing it. This requires a little bit of practice. It really helps.
- Repeated or extended application of your brakes at high-speed can heat up the brake system and cause glazing, or brake fade. Brake fade will reduce stopping power. If during the braking practice, you notice increased stopping distances or a spongy brake pedal feel, allow the brakes to cool down before continuing.
- Just because you are well-acquainted with your brakes doesn't give you an excuse to make it a habit of making sudden stops or tailgating. Always be aware of the road, keeping a safe distance from pedestrians and other cars.
- If you overstep the OSP you may lose the ability to steer. While braking (as stated above) steering should be kept to a minimum, but losing traction could make the vehicle go in a direction which is not desired. Be sure to be comfortable with theextra practiceon step 3
- Never break the law! Obey speed limits, research state and local laws, and be sure to obey all the laws.
- Always drive safely. Be observant of pedestrians and other vehicles.
- Any practicing you do should not be done on public streets! Your own private property is the best.
- Don't put an automatic transmission in reverse attempting to slow the car down. There's a chance it will stall the engine and you will lose power steering and braking.
- Practicing panic stops that results in leaving rubber on the pavement may rotate the tire on the rim. This will make the tire unbalanced which will result in a rougher ride. Tire balance will need to be checked after such an exercise.
- Panic stops may cause rotors on disk brakes to pulsate and vibrate the steering wheel under braking. This is commonly inaccurately described as "warping" the rotors. Even on race cars, the rotors don't warp. What causes this is the brakes being overheated. When the pads become overheated, they leave residue on the rotor. Typically, this happens after a panic stop or at a stop light when the brakes remain depressed. They are not allowed to cool naturally. Pad material is transferred to the rotor at the location it is being held tightly. This uneven buildup of material will be noticed whenever the brakes are applied again.
