A properly functioning brake system is super important for cars. But have you ever wondered what makes the brakes work so well? The answer is brake oil or brake fluid. These lubricants ensure your vehicle stops smoothly when you need to. Whether you’re a seasoned driver or a newbie just getting to know your car, understanding brake fluids is essential. So, let’s get to know how brake fluid works, why it matters, and how to take proper care of it.
Brake fluid, also known as brake oil, is a type of hydraulic fluid that plays an important role in your car’s braking system. The word ‘hydraulic’ might sound fancy, but it just means using fluid to move things. So, when we refer to hydraulic brake oil in India, we’re just referring to these brake oils that help cars stop smoothly.
Braking often generates a high amount of heat. Thus the brake fluid is made to withstand high temperatures and pressures without boiling or freezing. The brake fluid also ensures that the pressure is evenly distributed to the brake pads.
How it works – When you press the brake pedal of your car, the brake fluid transfers the force to the brake components. This is how your car comes to a stop. Think about it, without the brake fluid, the braking system would fail.
It is extremely important to maintain proper brake fluid levels. This is because a brake fluid fulfills the following functionalities:
Brake fluid ensures that the right hydraulic pressure needed for braking is maintained. Without the right pressure, there is a chance for the brake system to fail. Thus the brake fluid plays a significant role in preventing brake failure.
The brake system of your car has to work perfectly even in adverse conditions. In other words, the braking response must be consistent under varying temperatures and pressures. Your brake oil facilitates this. It maintains the performance of the brake system and ensures a reliable braking response.
Brake fluid absorbs moisture, preventing moisture from accumulating in the brake lines. This will ultimately help prevent rust. This will also reduce the risk of vapor lock. Vapor lock occurs when moisture turns into vapor under high temperatures.
A lesser-known functionality of brake oil is corrosion protection. Moisture buildup in the brake lines is bound to cause rust and corrosion in your brake system. However, any high-quality brake oil can prevent this, prolonging the life of your car’s braking system.
If you regularly check and replace your brake oil, it will maintain the efficiency of the braking system. This will ensure optimal performance and reduce wear on brake components.
Now let’s discuss the different types of brake oil:
This is a common type of brake oil that works well for regular driving conditions. However, this glycol-based brake oil is not suitable for high-performance conditions.
The DOT 4 is glycol-based and has a higher boiling point than DOT 3. This makes it the right choice for vehicles that undergo intense braking. Opt for a high-quality brake fluid like Addinol Brake Fluid DOT 4 if you are a spirited driver or if you have a heavy vehicle.
Unlike the brake oils we discussed till now, the DOT 5 is silicone-based. This means that it doesn’t absorb moisture. Obviously, this makes it the perfect fit for vehicles that are used in wet conditions. However, these brake oils are not recommended for everyday vehicles.
This is another glycol-based brake oil that is ideal for high-performance cars. With a higher boiling point than DOT 3 and DOT 4, this brake oil is commonly used in racing vehicles and sports cars.
Fully synthetic fluids are advanced brake fluids designed to provide better performance and durability. They can handle higher temperatures and pressures, making them ideal for high-performance cars and extreme driving conditions.
Choosing the right brake oil is important and it’s not as complicated as it might seem. The first thing to do is to check your car’s manual. The manufacturer usually specifies the type of brake oil that works best for your vehicle. If you’re unsure, you can also ask a mechanic, who can recommend the best option based on your driving conditions.
If you live in a hot region or frequently drive on hilly terrains, opt for a brake fluid with a higher boiling point like DOT 4 or DOT 5.1. For instance, in India temperatures can soar and traffic can be intense. In such a condition you need brake oils that can withstand high temperatures and prevent brake fades. You can follow these extra tips to make the right choice:
So, there you have it – a comprehensive guide to brake oil. It might not be the most talked-about fluid in your car, but it’s definitely one of the most important. It ensures that your brakes work properly, provides corrosion protection and ultimately keeps your vehicle safe and efficient. Whether you’re driving a compact car or a high-performance sports car, choosing the right automotive brake oil can make all the difference in your driving experience. So, the next time you’re topping up your fluids, don’t forget to check that brake oil too.
