What does the brake fluid reservoir do

Brake fluid reservoirs are canisters that connect to the brake master cylinder. The brake fluid reservoir stores your vehicle’s brake fluid and protects it so that your hydraulic braking system can work properly.

What happens if brake fluid reservoir is empty?

If the fluid level gets too low in the reservoir, air will eventually be drawn into the system, past the master cylinder (the part operated by the brake pedal that pushes fluid to the wheel cylinders) into the brake lines.

Do I need to bleed my brakes after adding fluid?

Can You Add Brake Fluid Without Bleeding? Bleeding is not a mandatory part of this process, so yes, you can do it without it. … Bleeding is something you should do when you completely drain the reservoir and push the brake pedal or when there’s a leak because it lets air bubbles into the lines/pipes.
