SUVs aren’t going anywhere, nor will we see a decline in their popularity anytime soon. Every year, there’s a new type of SUV being launched or modern features being updated.
One thing about SUVs that isn’t discussed enough is their ever-important braking system. Due to the large size and weight of an SUV, they typically require much more stopping power in comparison to other standard passenger cars.

As a trusted automotive expert, braking systems are not something Subaru shies away from. In fact, we conduct numerous road safety tests each year so that we can remain the top-rated safety pick for another 14 consecutive years. In this blog post, we’ll explore the different types of brake systems in SUVs, the factors that affect their performance, and the benefits of choosing an SUV with advanced braking systems.

Understanding SUV Braking Systems

Did you know that SUVs have a different type of braking system compared to regular cars? Due to the larger size and weight of an SUV, it requires much more force to stop and this is the main reason why most SUVs come fully equipped with larger brake pads and rotors.

SUVs use two main types of braking systems, namely Hydraulic and Regenerative brakes.

• Hydraulic brakes rely on hydraulic fluid to transmit force from the brake pedal to the brake pads. When applying pressure to the pedal, the hydraulic fluid creates pressure and causes the brake pads to press against the brake rotors.
• Regenerative brakes use electric motors to slow down the vehicle while converting the kinetic energy into electric energy, which is then stored in the vehicle’s battery.

In addition, many modern SUVs are equipped with anti-lock braking systems, ABS for short. This helps prevent the wheels from locking up during hard braking on slippery surfaces. Furthermore, some other advanced brake assist systems can detect when the driver is trying to stop and will apply maximum braking force to reduce the stopping distance.

Another unique braking system is the automatic emergency braking system. This can detect a potential collision and automatically applies the brakes to avoid or minimise the impact. Emergency braking systems, on the other hand, allow the driver to apply maximum braking force in case of an emergency without locking any of the wheels.

Factors Affecting SUV Brake Performance

There are plenty of factors that can actually affect the performance of an SUV braking system. Let’s get into it.

• For one, the weight and size of an SUV is something to consider. A general rule of thumb to remember is that the larger and heavier the SUV, the more braking force it needs to stop. 
• The next thing to consider is the type of driving conditions. Wet or slippery roads can also affect the performance of the brakes. 
• Your SUV needs strong and durable tyres to drive smoothly. The condition and quality of the tyre says everything. If it is worn or underinflated, it can dramatically affect the stopping distance of an SUV.
• High-quality brake pads and rotors can provide better stopping power and reduce wear and tear on the braking system.
• You can’t forget about maintenance and frequent SUV inspections. Regular inspections are crucial to ensure the optimal performance of an SUV’s braking system.
• Last but not least, driving style and habits can also affect the lifespan and performance of the brakes.

How Long Should Brakes Last on an SUV?

Brake pads wear out more frequently, whereas brake rotors tend to last much longer. Generally, you should look at replacing your brake pads after each 100,000km and your brake rotors every 112,000km. Again, this is in general situations, and the lifespan of brake pads and rotors can vary, having you replace parts sooner than expected.

Some factors that affect brake pads and discs include:

• Poor driving habits
• Bad road conditions
• Maintenance frequency

Regardless of the above, you should always keep an eye out for signs of worn-out brakes, which can be grinding and squeaking noises, pulsation in the brake pedal or reduced stopping power.

Troubleshooting Brake Problems on an SUV

While having brake problems is somewhat normal, it is, however, not recommended to leave it until the very last minute to have it fixed. If you’re experiencing brake problems on your SUV, it’s important to diagnose and fix it as quickly as possible.

Some common brake problems include loud brake noises, vibration or shuddering. Most of which is caused by worn-out brake pads or rotors, improper installation or air in the brake lines. If you find that your SUV’s brakes are making weird noises, start shuddering or more; it’s best to have it inspected by a professional mechanic to identify and fix the issue.
Here are some of the most common brake problems that SUV drivers encounter, along with their possible causes and solutions:

• Brake Noise

> Problem: If you hear a squealing, grinding, or squeaking noise when you apply the brakes, it could be due to worn-out brake pads or rotors. It could also be caused by debris or rust on the rotor surface.

> Solution: Check the brake pads and rotors for wear and replace them if necessary. Clean the rotor surface using a wire brush and brake cleaner spray.

• Brake Vibration

> Problem: If you feel a pulsation or shaking sensation when you apply the brakes, it could be due to uneven brake pads, warped rotors, or worn-out suspension components.

> Solution: Have the brakes inspected by a professional mechanic to determine the cause of the vibration. Replace the brake pads and rotors if necessary and have the suspension components checked.

• Brake Fluid Leak

> Problem: If you notice a puddle of fluid under the SUV or the brake pedal feels spongy or goes to the floor, it could be due to a brake fluid leak.

> Solution: Check the brake lines, callipers, and master cylinder for leaks. If you find a leak, have it repaired immediately and refill the brake fluid reservoir.

• ABS Warning Light

> Problem: If the ABS warning light on the dashboard stays on or flashes, it could be due to a malfunction in the ABS system.

> Solution: Have the SUV’s ABS system inspected by a professional mechanic to determine the cause of the malfunction.

Why Choose an SUV with Advanced Braking Systems?

There are many reasons why you should choose an SUV with advanced braking systems. Apart from making you feel like you’re on top of the world and completely safe, here are some valuable benefits of having an SUV with high-quality and advanced braking systems.

• Enhanced safety features such as Anti-lock Braking systems (ABS), Electronic Brakeforce Distribution (EBD) and Brake Assist all contribute to improved safety on the roads.
• Shorter stopping distance. This can help reduce stopping distances and allow SUVs to come to a stop much quicker and safer without locking the wheels.
• Reduced risk of accidents and collisions. SUVs with advanced braking systems provide better control and stability, which can reduce the risk of accidents and unwanted collisions.
• Improved driving experience. Thanks to the intelligent and adaptive features of advanced braking systems, it can enhance the driving experience. For example, sensors can detect potential collisions and offer a layer of safety and peace of mind to the driver.
• Outstanding customer satisfaction ratings. The people have spoken. Almost every Subaru owner has provided amazing testimonials and expressed their love and appreciation for their SUVs.

SUVs have different braking systems compared to normal cars due to their weight and size. Investing in an SUV with advanced braking systems can provide numerous benefits, such as enhanced safety features, shorter stopping distances, and improved driving experience. It’s important to keep in mind the factors that affect SUV brake performance and the signs of worn-out brakes.

Regular maintenance and inspection can help prevent brake issues and ensure your SUV’s braking system is in top condition. As a trusted automotive expert and advisor, Subaru recommends considering SUVs with advanced braking systems for safer and more reliable driving.
