Understanding The Various Types of Brake Fluids

Imagine you are driving a car which is beaming up more 100km/hr, and suddenly you spot a red signal, you apply brakes, right? Just imagine stopping an object that is running at speed. It is a difficult job. And this difficult job is performed by the brakes of a vehicle. It is one of the most important parts of a vehicle. Brakes help to hold the motion of a vehicle and bring it to rest. However, it is important to maintain the brakes and provide it with fueling every now and then. This brake fluid helps the smooth functioning of the brakes and the car. However, as observed brake fluids are one of the most neglected areas of the vehicle. You always think why bother and worry if the brakes of the car are performing well. This is overlooked but fueling the brakes is important because it helps to transfer the foot pressure to the brake or the hydraulic clutch system. It is important to understand that proper care and good maintenance is vital just like other fluids are important in the vehicles. When a person thinks about brake fluids, there are two things that spring up: What is the right time? Which fluids are the most compatible with the vehicle? We all have studied chemistry, and if you have a special inclination towards the subject, then you can check for yourself that this fluid has combinations of many types of glycols. A glycol is a mixture of alcohol based fluids and non-petroleum. In addition to this, there are many silicon fluids that can’t be mixed with other fluids. A brake fluid should maintain some kind of specific properties. When you drive for a while, you will notice that brakes get hot and reach up to 1200 degrees and hence needs a high boiling point. Also when it’s winter the brakes too get told, and hence it is important to understand the freezing point too. With these two extreme climatic changes, it is important to understand that brakes are made of rubber and hence should not damage the covering. Let’s learn more about these fluids, so that next time you are aware of the kind of fluid your brakes needs for a smooth functioning. There are 4 kinds of brake fluids. DOT 3 A DOT 3 is the most used type of brake fluid. This type of brake fluid is used in domestic cars. According to the SAE (Society of Automotive Engineers), a DOT 3 is equipped enough to absorb 2 percent of the volume in water measurements every year. However while using this brake fluid, it is important to understand the due to excessive moisture, there can be corrosion in the entire brake system which can lead to issues like a vapour lock inside the system or a spongy pedal too. This fluid has a tendency to absorb moisture from the atmosphere and hence can damage the paint on the car.

DOT 4 This fluid is processed to use for all vehicles. The boiling point of the DOT 4 is higher than the DOT 3, and it does not absorb moisture that quickly. The DOT 3 AND DOT 4 are considered to be interchangeable. It is advisable not to use a DOT 3 for a vehicle that is already using a DOT 4. This fluid is used for very high street and many high performances. DOT 5 A DOT 5 brake fluid is referred as a synthetic brake fluid. It is a silicon based brake fluid, and it does not absorb any kind of moisture. Many street based drivers use this kind of synthetic fluid because it is not corrosive to the paint of the car unlike DOT 3 and DOT 4. This fluid does not harm other brake components. This helps to preserve your car for a longer period of time. However, this synthetic fluids have a few drawbacks like with compression it can make the pedal spongy. The colour of DOT 5 is different from DOT 3, and DOT 4 and hence can not be mixed with other fluids. DOT 5.1 A DOT 5.1 is a non-silicon based polyglycerol. This fluid has a boiling point over 500 degrees. A DOT 5.1 can be mixed with both DOT 3 and DOT 4. A DOT 5.1 generally has a higher rate of boiling point. This fluid is highly recommended for high duty performance. Always remember to use the right kind of fluid for your brakes. This will help in the smooth functioning of the vehicle.
