Do you bleed brakes with truck running or off?
6 Answers. If what you meant was bleeding the brakes at the calipers to remove air from the system, you should bleed the brakes with the car off. While ‘pump’ was the wrong word to use, the brake booster runs off the engine vacuum (it’s a large diaphragm that multiplies brake force), and this should not be active.
Why are my brakes still spongy after bleeding?
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.
Do you need to start car to bleed brakes?
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.
Should vehicle be running while bleeding brakes?

How do you fix spongy brakes after bleeding?
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. (Bleeding the brakes uses fluid to push air out of the brake system.) Over time, brake fluid absorbs moisture.
Why does my brake pedal go to the floor after bleeding?
Because of high pressure in the brake fluid, the brake pads squeeze into the rotors causing friction resulting in the vehicle stopping. If you have a brake fluid leak, you’ll feel your brake pedal going to the floor because there isn’t enough force to compress the piston.
