What does it mean to depress a brake pedal?
It means push the brake pedal down with your foot, preferably your right foot! This action slows the vehicle’s speed (if you’re moving) and if you keep pushing down steadily and holding, the vehicle will eventually stop.
What happens when you press the brake pedal?
When the brake pedal is pressed, the two-way valve internal to the booster moves in conjunction with the pedal. The valve closes the pull of vacuum to the rear of the diaphragm and the engine vacuum is only pulling on the front while atmospheric pressure is allowed into the rear of the booster.
How to diagnose hard brake pedal master power brakes?
A) With the engine not running, press and depress the brake pedal several times to remove any vacuum from inside the booster. B) On the last push of the brake pedal, hold moderate pressure on the brake pedal. Don’t push like you are panic stopping, but simply hold pressure like you are sitting at a red light.
Why does my vacuum not kick in when I press the brake?
You press the brake and the boost doesn’t kick in, so the brake is difficult/impossible to push. Typical responses online are that they suspect that the brake was depressed a few times after the car was turned off and it drained the vacuum system. This is not the case however.

Went out into the Jeep to take my father to lunch and it wouldn’t start. Had to press the unlock button on the FOB a couple of times and then it started. Same thing happened after lunch. Just a little bit frustrating.
When do I need to depress the brake pedal?
How far you have to depress the pedal depends on the reason for doing it. If you’re starting the engine (e.g. in a Chrysler 300c, the instrument panel instructs you to “Depress brake pedal and press the Start button.”), then you only need to push it down a short distance.

Why does the brake pedal go to the floor when starting an engine?
It is a built-in safety feature. There is an adjustment on the brake pedal position switch that can be adjusted so you do not have to press the pedal down so far and hard. When you do push the brake pedal down it should not go to the floor when starting the engine, unless there was a loss in brake fluid or other problems.
