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 push the brake pedal.
Check the brake switch up under the dash on the brake pedal. Lie on the drivers floor, look up and then push the brake pedal with yoru hand and see if there is any kind of electrical connector that actuates the brake lights when you push the pedal in.
Start the engine and then push the brake pedal down. If it is soft and easy to push then the booster is okay. If booster is BAD the brake pedal would be hard to push.
Push the brake pedal? What, exactly, are you asking??
sounds like you have a leak in your Brake Boost Controler, you should also check to see if there is any leaks in the vacuum lines that connect the engine to the brake booster.
Key on, engine off. (if push button start, press button twice without touching brake) press gas pedal to the floor three times.Key on, engine off. (if push button start, press button twice without touching brake) press gas pedal to the floor three times.
Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
Push the brake pedal to released.
usually they will leak out the back by the booster, your brake pedal will slowly go to the floor at stops or the brake pedal will go right to the floor when pushed.
Something is impairing the brake pedal to go to the floor. Only a mechanic can tell you what is happening.
Safest way: Set Parking brake Push clutch pedal to the floor Shift to neutral Turn key to start
The brake pedal will go to the floor but will have absolutely no effect on stopping the vehicle. When you push on the brake pedal it moves the fluid through metal tubes (called brake lines) to force the brake pads against the rotor which slows and stops the car. No fluid means nothing is in there to make the brake pads engage the rotors.
no you have a brake fluid leak somewere
There is an electronic relay switch which turns on the rear brake lights-It's located behind the brake pedal- It clicks when you push the pedal down, making contact.
Just above the brake pedal on the pedal shaft.
look on top of the brake pedal under the dash and you will see the switch, with one hand push the brake pedal down and with the other hand push the brake switch in as far as it will go in it's holder and then pull the brake pedal back with your hand to set it.
The clutch pedal.
ouch,are brakes adjusted correctly/ sit in vehical and pump pedal to get a full pedal,then hold pedal to see if it bleeds off and goes to floor,if it stays, replace shoes and pads if it goes to floor, there is a fluid leak somewhere is there brake fluid in the resevoir/ are there any brake fluid leaks ,check backside of wheels there is a brake fluid pump, on the chassis rail about level with the front of the front door on the left side.if this pump is bad your pedal will go to the floor
Do you mean when you push the pedal " hard " you hear noise..........if so could be the ABS..........if not, then please have your brakes checked for safety.
Near the top of the brake pedal pendulum is a push-switch when the brake pedal is moved this switch will trun the brake lights on and off.
probably have broken parking brake cable.
Please re-phrase your question; it appears you are saying the brake lights come on when you push the brake pedal and the lights are working (normal operation). If the lights are staying on after you release the pedal, then the problem is with th brake light switch (sticking). Thanks Malcolm
The most common symptom of a master cylinder that has failed is that when you stop and hold your foot on the brake pedal it will slowly fall to the floor. This is called pedal fade and means the seals within the master cylinder are leaking. If you push the brake pedal and it does not return it may be defective. You may also see a leak at the master cylinder.
why is my brake pedal hard on 2003 sunfirer
