What Are The Different Types Of Brake Fluids?

There are different kinds of brake fluid for your car. Most fall into the DOT 3 and DOT 5.1 classifications. DOT 3 brake fluid is hygroscopic, which means it absorbs moisture from the air. DOT 4 and 5.1 brake fluids are non-hygroscopic. They’re typically used in collector cars and military vehicles. Here are some different types of fluids you can buy from brake fluid manufacturers in UAE.

DOT 3 brake fluid:

DOT 3 brake fluid is a cost-effective, reliable option. Its boiling point is lower than DOT 4 brake fluid. This difference is due to the way brake fluid absorbs water. Brake fluids from new containers have a dry boiling point of 401 degrees Fahrenheit, whereas brake fluids contaminated with 3.7% water have a wet boiling point of 284 degrees Fahrenheit. It is suitable for re-filling brake and clutch systems in heavy-duty commercial vehicles, 4WDs, and agricultural equipment. Because of its high boiling point, DOT 3 brake fluid can absorb up to 81% of water, reducing the risk of corrosion.

Silicone brake fluid:

Conventional brake fluids are classified according to their chemical composition and boiling points. The former is made of glycol, polyalkylene glycol ether, or mineral oil. This fluid is not used in most vehicles. There are also D.O.T. 3 and 4 brake fluids, which are silicone-based, as well as D.O.T. 5.1, which is a diethylene glycol-ester base. The specifications indicate the minimum boiling points of these fluids.

Non-silicone brake fluid:

Silicone-based brake fluid is preferred by many motorists as it is compatible with anti-lock brakes. Silicone brake fluid is thicker than glycol-based brake fluid and is incompatible with other DOT specifications and mineral brake fluid. Silicone brake fluid is a relatively recent development that was introduced in the early 1970s. Many organizations praised this fluid for its safety and reliability and predicted that it would become the brake fluid of the future.

Silicone-based brake fluid is much less likely to cause an accident because it has a lower boiling point and does not absorb water. Silicone fluid is hydrophobic, meaning that it does not absorb moisture and will not corrode metal brake parts. Silicone brake fluid also has higher compressibility than glycol brake fluid, making it easier to pour. Silicone brake fluid is also more durable than glycol, which tends to rust and cause brake pedals to become mushy.
