DOT 4 BRAKE FLUIDS 

 

Brakes are essential for any car and this makes brake fluid one of your car's most important components. Brake fluids resist the moisture that can cause vapour lock brake failure, protect against corrosion, and withstand high brake temperatures. Brake fluid Dot 4 is used in the brakes and clutches of most modern cars.

 

WHAT IS BRAKE FLUID?

 

Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in cars, motorcycles, light trucks, and some bicycles. It transfers force into pressure and amplifies braking force. Most brake fluids for cars are glycol-ether based, but mineral oil and silicone-based fluids are also available.


WHAT DOES BRAKE FLUID DO?


Modern engines work at high pressure and place heavy demands upon braking systems. When we think about brakes we typically think about discs and pads and expect them to experience wear and tear. Important though discs and pads are, they are part of a hydraulic system that relies upon a brake fluid to function and will not work without a brake fluid. A healthy brake fluid is therefore essential. For the majority of cars this will mean a brake fluid Dot 4.
