If sitting still in your car with the engine running you can apply the brakes and the pedal slowly goes towards the floor you have a defective brake master cylinder. The only repair is to replace the master cylinder. This is a very dangerous situation and must be repaired immediately. Failure to replace the master cylinder may result in an accident.

If you start to skid you should apply a quick pumping motion to your brakes if you have anti-lock brakes.?
False. If you have anti-lock brakes, just press firmly on your brake pedal and the computer will take over. Do not pump the brake pedal.

When you put on the brakes by pushing down the brake pedal air pressure is applied to the brake pads?
In all cars and most trucks HYDRAULIC pressure is used to apply the brakes. In an air brake system such as is found on medium and heavy duty trucks the air is actually released to apply the brakes.
What brake pedal is the cause of air being in the brake system?
The brake pedal has nothing to do with it. If air is in the system then bleed the brakes.
How do you test hydraulic brakes for leaks?
if the vehicle has hydraulic brakes, pump the brake pedal three times. them apply firm pressure to the pedal and hold for five seconds. the pedal should not move. if it does, there may be a leak or other problem. get it fixed before driving.
What is the brake pedal reserve distance?
It is the distance between floorboard and pedal top, when the brake pedal is fully depressed (after applying brakes).
Can the brake booster cause your brake pedal to go to the floor?
No, a busted brake booster will not cause the brake pedal to go to the floor. It will however cause the brake pedal to be extremely hard to push. A defective master cylinder will cause what you describe. Replace the master cylinder and bleed the brakes. It can because it happened to me. The booster lost vaccum and the pedal went to the floor. Sorry, you are wrong. The only reason the pedal went to the floor was because the master cylinder failed. The brake booster only boosts the pressure on the master cylinder and allows you to not have to push so hard on the brake pedal. Cars of yesteryear did not even have a brake booster and they stopped just fine albeit you had to push the pedal allot harder than with power brakes. A failing brake booster will not cause your pedal to go to the floor although it might cause it to go lower than normal before the brakes apply. As long as the master cylinder is good you will still have brakes, but you will have to really push hard and might even have to pump them up in order for them to stop the car.
When you apply the brakes why does the pedal depress all the way to the floor?
Check your brake fluid level in the master cylinder... you may have a leak some where
Can a brake pedal malfunction make your brake lights not work?
Usually that would be caused by a faulty brake light switch connected TO the brake pedal. If the brakes work the pedal is probably ok.
What could cause the brakes and brake pedal to stick when brake pedal is pressed?
Check around brake pedal for something rubbing. If OK, I'd look into the master cylinder.
