Check the master cylinder.

Answerwhen you compress the brakecylinders in the rear to make room for the new once you have to pump the brakes until the new pads touch the rotors.it might take 2 or 3 pumps,after that you should be fine.If that don't work check for leaks....good luck

Have a helper pump the brake pedal on the 2001 Jetta several times then hold it down. With the pedal down, loosen the bleeder valve at a wheel cylinder and let some fluid flow til the pedal goes to the floor. Close the valve and repeat until the fluid does not have any air coming out with it. Do the same thing at the three other wheels.

a low brake pedal indicates worn brake pads and shoes.have then replaced

Two things, one the brake light switch needs to be replaced, it sits on top of the brake pedal. There is a recall for this switch for free, called an N4 recall. If you have not had this done then do so. The last thing thing is you have some bulbs out. They are single filament bulbs.

You don't have brake fluid There could be air in the system and it requires bleeding to rid it of air. If the vehicle is an older one, the master cylinder may be porus or the bore pitted. It should be resleeved or replaced. The seals could also be flat. Jam your foot down hard on the brake pedal. Is the pedal high? Does it sink to the floor if you rest your foot lightly on the pedal? www.powerbrakeandsteering.co.za

Try bleeding your brakes. If there is air in the system it can give a spongy feeling to your brake pedal and require you to pump your brakes and/or put your brake pedal to the floor.

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.

First, make sure the master cylinder is filled with brake fluid. If it is low, there may be a leak somewhere in the brake lines or a brake cylinder. If the master cylinder is bad, you can normally pump the brakes up, but the pedal will slowly sink to the floor again. The master cylinder needs to be replaced or repaired.

Behind the brake pedal stem. You need to crawl underneath the dashboard in order to see it.

did you bleed brake master if you did check brake hoses see if they move when pushing pedal down if it has rear brake drums see if wheel cylinders are leaking rear shoes could be out of adjustment

Usually means they probably didn't bleed the brakes or did not top off the brake fluid

There is a safety switch located behind your brake pedal arm behind the actual brake pad that evidently has gone bad that must be replaced, I believe average cost is @$20.00 for the part.

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

Although they can fail abruptly the most common symptom you normal see is that when you stop and hold pressure on the brake pedal it will very slowly go down toward the floor. It will not hold steady pressure because the seals are bad. It must be replaced immediately.

Adjust the brake switch located on either the brake lever itself, or it will be attached underneath the dash. SOunds like your brake switch is off or broken. Look at the brake pedal and there is a switch around it that gets activated by you pushing the pedal - that is what needs to be adjusted or replaced. The brake light switch has probably come loose or broken. Look under the dash near the brake pedal arm. There is a switch attached to a bracket.

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.
