Why is my brake fluid low?
COMMON CAUSES OF LOW BRAKE FLUID. 1. Worn out brake pads. Brake pads have the function of squeezing the brake disc thus slowing down the wheel. They logically wear out over time as the friction material on the pad is softer than the disc. The level of brake fluid in the system is calibrated when the brake pads are new.

What happens when brakes are worn down?
Worn brake pads – When pads are worn down, the caliper piston is forced to travel farther to the brake pads, away from the housing.

What is brake fluid?
Brake fluid sometimes referred to as hydraulic fluid, is used to move the parts of a brake system. Brake fluid should reach certain standards to work effectively. It must stand a high temperature. It must be free from contaminants like water, air, and dirt. The system must have good working parts.
Why is my brake system sealed?
The system should be completely sealed. Leaks cause excessive loss of brake fluid which results in more pressure applied when pressing pedals. The brake system has to sustain enough level of brake fluid to keep it working. Avoid implications when you’re not driving low with brake fluid.

Annoying noises. If you have no idea how will low brake fluid cause noise, think again. Low brake fluid causes squeaking. Low brake fluid noise is an indication that parts like brake pads are damaged. The repetitive applying of force causes damaged parts. 5. Leaks.
How does brake fluid affect rotors?
The pressure from the fluid causes the rotor to squeeze with the brake pads. Brake pads come in contact with the wheels to slow it down and eventually stop it from moving. To put it simply, pressing the pedal pushes the brake fluid down to the mechanisms of the brake system to apply pressure to the rotor.

What happens when you put your foot on the brake pedal?
That means when your foot on the brake pedal operates the master cylinder which squeezes the fluid into the lines that force is transmitted almost completely to operating the brakes. When there is air in the line all you do is move the air around a little and you apply very little force into operating the brakes.
Why does my brake pedal feel spongy?
When you have only a little air in the lines the pedal just feels "spongy" because you compress the bubbles down to nothing and then you are closing the brakes. When there is a lot of air, or no fluid at all, you just don't operate the brakes at all, and you have a very bad day..
Is brake fluid hydraulic or lubricant?
There's a bit more to it, but that's the simplified version. Bottom line, unlike your engine where the fluid is a lubricant, in your brakes the fluid is a hydraulic fluid.
