What happens if I get air in my master cylinder?
Bleeding the master cylinder and brake lines is the process of removing air from the hydraulic lines. Air bubbles will also make the brake pedal feel “spongy,” meaning when you press the brake pedal down, little or no braking force will be felt by the driver.
How do you get air out of your brake fluid line?
If your vehicle has squishy-feeling brakes, the way to get the air out of the lines is to bleed the brakes. To do the job, you need either a brake bleeder wrench or a combination wrench that fits the bleeder nozzle on your vehicle, a can of the proper brake fluid, a clean glass jar, and a friend.
What happens if air gets into brake fluid?

What happens when you let the master cylinder run dry?

Do you need a new master cylinder for ABS?
If the module is also clear, you may just need a new master cylinder. While running pump the pedal until it is firm. If it holds in the same place it is air in the lines, if it slowly descends to the floor it is the master cylinder. No, I didn’t bleed the ABS module…
