I do not have a brake bleeding kit, but just want to get any air out of the lines since my stopping power is almost non-existant. Can you flush the entire system by pumping the brakes, or should I just add Dot 4 fluid as needed and bleed brakes by pumping the brake pedal.

I Just made one of these last weekend, go down to walmart/lowes/home depot and get yourself a 10$ insectacide pressure sprayer kit. Take 10-15 minutes and open all the different models and pump them up to make sure that they will hold pressure for at least 5 minutes. Then go to the junkyard and get a brake res cap off of pretty much any BMW (mine's from a 318) just make sure that the gasket is good and the cap is not cracked. Probably cost $2 at most. Then get about 5' of 1/4 silicone tubing and run it through the cap. If it's 1/4" tubing, it will be tight enough in the cap that you don't need sealant. Pump up the bottle a little bit and go and crack one of the nipples...(run some of the tubing down to a catch tank).
After the first one, you get a good idea of how much pressure you need. If you want to get fancy, put a pressure gauge in the bottle somewhere. I think you want about 15-20 psi...
Good luck

If bleeding doesn't fix it, check your master cylinder. I bled my brakes a bunch of times, then bought speedbleeder valves for it, because I thought I was doing it wrong, or something. But, it turned out to be the brake master cylinder. Put a new one in and now the brakes are good. I got the speed bleeder valves online and they work good for one person to do the brakes, and I have one on the clutch too.

investment you can make. The best brakes in the world won't work if you've got air in your lines.
To pump the brakes it takes two people. One to pump & hold, one to bleed. it's pretty easy. pump two or three times till the pedal is hard then hold, bleed a little, close the valve before the pumper releases the pedal. repeat...

It works fine at 8 - 10 psi.

I use a small vacuum pump (intake of an air compressor will do..) and a quart jar with copper tubing soldered to the lid. Pull a vacuum through the jar, put tubing over the brake nipples, open the nipples and it will pull brake fluid through the system and catch it in the jar. Only takes a few minutes.

push it all the way through the back lines without re-pumping a few times. 15-20 will do the whole car on one shot. just my experience.

come to think of it I do have a topsider, it pulls oil from the oil pan with out having to lift the car...I can just put this over a loosened nipple and it will bleed the system.

did it the old fashioned way. i *have* a motive bleeder, but the cap doesnt fit on the dodge reservoir. so my sister and law sat in the car and pumped while i did the bleeders. No Big Deal. =)

beyond it's normal range of travel. Often the master cylinder bore is rough out there, and that can damage the piston seals. It's easy to damage the MC if you're not careful.
