Brakes are bled with the engine off. A running engine supplies a vacuum boost to the brake system. To properly bleed all the air from the system, there needs to be NO boost. Just pump the brake pedal until a solid pedal is felt, then bleed each caliper (if equipped) until the air is evacuated.

If air gets into the brake lines, it can prevent brake fluid from flowing properly, causing the brake pedal to feel spongy or soft. If the brakes are soft or spongy, this is a good time to change or flush the brake fluid. Flushing the brake fluid, commonly called bleeding the brakes, gets rid of the air.

Can ABS lock up your brakes?

The Brakes Lock Up

The ABS system is specifically designed to prevent any wheel from locking up during heavy braking. So, when an ABS control module fails, you’ll likely notice it when you’re braking heavily. A bad ABS module can behave erratically, making your brakes lock up even under normal braking.
