Pidurivedelikku

Pidurivedelikku, commonly known as brake fluid, is a hydraulic fluid used in brake systems and power steering systems. It is a non-compressible fluid that transmits pressure from the brake pedal to the brake calipers or wheel cylinders. When the driver presses the brake pedal, the master cylinder generates hydraulic pressure that is transmitted through the brake lines to the brakes. This pressure forces the brake pads to clamp onto the brake rotors or the brake shoes to expand against the brake drums, slowing down or stopping the vehicle.

Brake fluid is essential for the proper functioning of a vehicle's braking system. It must be able to withstand high temperatures generated during braking without boiling or degrading. It also needs to have a low viscosity to ensure smooth operation of the brake system. Over time, brake fluid can absorb moisture from the atmosphere, which can lower its boiling point and lead to corrosion within the brake system. Therefore, it is recommended to inspect and replace brake fluid at regular intervals as specified by the vehicle manufacturer. Different types of brake fluid exist, typically classified by DOT standards (e.g., DOT 3, DOT 4, DOT 5), each with specific properties and compatibility requirements. Using the correct type of brake fluid is crucial for maintaining the safety and performance of the braking system.
