Fluid Reservoir

A brake fluid reservoir in a car is an important component of the braking system. It stores and supplies brake fluid to the brake system when needed. Brake fluid is a special hydraulic fluid that is used to transfer force from the brake pedal to the brake calipers or wheel cylinders, enabling the vehicle to slow down or stop. The reservoir is usually located near the engine compartment and is connected to the master cylinder, which is the main control unit for the braking system.

The brake fluid reservoir is designed to maintain a proper level of brake fluid at all times. It acts as a storage tank, ensuring that an adequate supply of brake fluid is available to the braking system. The reservoir also plays a crucial role in preventing air from entering the system, as air bubbles in the brake lines can reduce braking performance or lead to a complete brake failure. To check the brake fluid level, a transparent plastic or glass window is often built into the reservoir, allowing the driver or a mechanic to easily inspect the fluid and determine if it needs to be topped up or replaced. Proper maintenance of the brake fluid reservoir is essential for efficient and safe braking.
