The Composition of Brake Fluid
Brake fluid is a vital component of a vehicle’s braking system, responsible for transferring force from the brake pedal to the brake pads, resulting in the car coming to a stop. It is crucial to understand the composition of brake fluid to ensure the proper functioning of the brakes.
- What is brake fluid?
- Key components of brake fluid
- Boiling point enhancers
- Anti-corrosion additives
- Anti-wear additives
- Anti-oxidants
- The chemical that brake fluid is made of: Glycol-based or Silicone-based
Brake fluid is a type of hydraulic fluid used in hydraulic brake and clutch applications. It is a non-compressible substance that plays a crucial role in transmitting force from the brake pedal to the brake pads or shoes.
Brake fluid is typically made up of a mixture of various chemicals, each serving a specific purpose in ensuring optimal brake performance. The key components of brake fluid include:
There are two primary types of brake fluid based on their chemical composition: glycol-based and silicone-based.
Glycol-Based Brake Fluid
Glycol-based brake fluid, also known as DOT fluid, is the most commonly used type of brake fluid in vehicles today. It is a blend of polyethylene glycol and various additives that provide specific performance characteristics.
