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 luckHave 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.
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
a low brake pedal indicates worn brake pads and shoes.have then replaced
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.
Check the caliper slides (may be frozen) should slide freely to compensate for brake pad wear
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.
