What is a blown brake line?
Motor vehicle brakes are usually hydraulic, which means that the brake pedal is basically a pump. pushing the brake pedal pumps some brake fluid through pipes and hoses out to the brakes at the wheels, activating the brake pads. The pipes and hoses are also referred to as "lines", and they can spring leaks if they get too old, damged and worn.
Why does our 1997 k2500 have low brake pedal only when 350 motor is running?
Pedal pumps up fine, but when you run the engine, the brake booster applies more force to the lines. Thus compressing any air that may be in there. You will need to bleed the brakes more. I sometimes bleed the brakes with the engine running to correct this.

What does ABS mean on a 1999 ford E150 XLT warning light?
It means that your Antilock Brake System is not working. The ABS system works when the system senses that the vehicle is going to go into a skid. While you hold your foot down on the brake pedal, the ABS system pumps the pedal to keep the vehicle straight while stopping. Chances are that you have a bad wheel sensor.
2001 impala you hear a eeerrrhhhmm sound as your brake pedal forces itself upwards for about 2 seconds that's when the message system displays service your traction then disables it?
the traction light comes on telling you there is a low traction condition, not that the system needs service. the anti-lock brake system is the noise you hear. it is a series of hydraulic pumps that is cycling the brake pressure on the locking wheel. that is also what you feel on the pedal. the system is working as it should.
Why does the brake pedal seem very soft even though brakes work?
asuming the brakes are fine. what we have is servo assistance all cars have brake servo's these unit's aid the driver to operate the brakes because with out servo assistance you could not stop the car on your own. how ever if you must check your brakes turn the car off now pump the brake pedal after 3 or 4 maybe 5 pumps of the pedal it should become solid if it not then get them looked at. but lets say they are now with the pedal feeling solid hold the pedal down as hard as you can now start the car now as you start the car the pedal should go down pretty much all the way down this is the servo kicking in which is great but if the pedal does not go down the servo needs looking at. and this goes for all cars .

How do you know if you need a master cylinder?
If you are sitting at a light with your foot on the brake and you feel the brake pedal slowly sink to the floor but it pumps back up and the brake reservoir stays full, you have a bad master cylinder. -OR, if the brake reservoir gradually lowers every day and you have to keep topping up the fluid. You check each wheel and they are all clean. -Then looking carefully at the master cylinder one day, you see the stains on the front of the booster - - -

Brake Pedal goes to floor after changing brakes on 2003 Saturn L200 and bleeding brakes throughly What could be problem Car is mint too new to be master cylinder 30K miles?
After changing the brakes the first few times you press on the brake pedal it will go to the floor; that's because the calipers haven't been pushed back to position. Remember that you had to retract the calipers completely before you could put in the new brake pads. Sometimes it takes a few pumps before the calipers are back in position. Make certain that the brake fluid is all the way up, then bleed the brakes again, and watch that fluid level. If it goes low for just one pedal push then you'll suck air again and you'll have to start over. Just one bubble of air in the brakes will cause trouble.
