Engine Braking Is It Harmful? Discover The Truth

When it comes to reducing speed, there are two options: using the brakes or engine braking.

Although engine braking is the most appropriate driving technique in some situations, many drivers still have doubts about how to do it and whether it damages the vehicle.

In this article, explore what engine braking is, how to do it correctly, its advantages and disadvantages, and precautions to take.

 

What Is Engine Braking? 

Engine braking means reducing speed by slowing down the engine.

In other words, this procedure consists of shifting down in the gearbox to reduce the speed of the vehicle.

This technique is useful on downhill slopes or when you want to slow down in a controlled manner.

 

Is It Better To Use The Brakes Or The Clutch To Slow Down?

Ideally, you should use a combination of both.

Engine braking is effective for controlling speed and reducing brake wear, especially on downhill slopes.

In emergencies, it is best to use the brakes to come to a complete stop.

 

When Should You Brake With The Engine?

Engine braking is particularly useful in the following situations:

• Long descents: helps control speed without overworking the brakes;
• Driving on slippery surfaces: provides greater control and reduces the risk of skidding;
• Tight corners: allows for a more controlled and safer approach;
• Heavy traffic: contributes to smoother and more efficient driving.

What Are The Advantages Of Engine Braking?

Although many people still associate this practice with more experienced drivers, the truth is that engine braking has several benefits for both the vehicle and the driver.

From reducing component wear to improving road control, discover the main advantages of this driving technique:

 

1. Reduces Brake Wear

When braking with the engine, the driver uses the resistance of the engine itself to slow down the vehicle, relieving the load on the brakes. This means that the brake pads and discs are not used as much, which extends their service life.

On routes with many descents or constant braking, this advantage becomes even more evident.

 

2. Prevents Overheating Of The Braking System

On long descents, continuous use of the brakes can cause them to overheat. This reduces their effectiveness and can cause serious malfunctions.

When braking with the engine, the effort is distributed, preventing excessive heating of the braking system components.

 

3. Increases Vehicle Control

Engine braking allows for more progressive and controlled deceleration. This is very useful in tight corners, on slippery surfaces, or during steep descents, where the risk of skidding is greater.

By using the engine to brake, the driver maintains greater traction and stability without relying exclusively on the braking system.

 

 

How Do You Brake With The Engine?

To brake with the engine, you should:

1. Take your foot off the accelerator;
2. Gradually reduce the gears;
3. Avoid sudden reductions. If you skip several gears at once, this can cause wear on the clutch and gearbox;
4. Only use the brakes when necessary, as engine braking should complement, not completely replace, the use of brakes.

To brake with the engine in vehicles with automatic transmission, check the settings for your model. Most models automatically adjust the gear to assist with braking.

 

What Are The Disadvantages Of Engine Braking?

Although this driving technique is very advantageous, poor execution can cause:

• A considerable increase in engine speed;
• Locking of the drive wheels;
• Wear on the gearbox.
• Deterioration of the transmission;
• Increased effort on the engine block;
• Greater wear on the engine.

 

Is Engine Braking Bad For A Car? 

Engine braking, when done properly, can extend the life of your brakes and improve driving safety.

However, sudden or incorrect braking can cause wear on the clutch and transmission.

 

Does Engine Braking Wear Out The Clutch?

Engine braking does not cause significant wear on the clutch, provided that the technique is performed correctly.

What can lead to premature wear of components is abrupt downshifting or excessive use of the clutch during braking.

 

Does Braking With The Engine Down Consume More Fuel?

In many modern vehicles, the fuel injection system cuts off the fuel supply when braking with the engine down, resulting in zero consumption during this period.

However, when coasting in neutral, the engine continues to consume fuel to keep running.

 

What Precautions Should You Take When Braking With The Engine?

To use this technique effectively and safely, you need to:

• Avoid multiple downshifts at once. Choose to shift down one gear at a time to avoid overloading the engine and clutch.
• Pay attention to the engine speed. Do not let the engine rev too high when slowing down.
• Combine this technique with the use of brakes. In some situations, it will be necessary to use the brakes in combination with engine braking.
