Anotherwords after 4 or so pumps > they are just about perfect. It is the nature of the system that the pressure in both systems (front and rear) will always be equal, unless one piston is bottomed out. It seems likely that if you didn't pump, but just pushed down 1 stroke, you would have one system working and the other one not. If you could determine which one was NOT working at that time, you would then know for sure where to look for your flaw. > Is it possible to vacume air somewhere but not leak fluid? It's possible, but in that case you would usually find your system getting worse each time you used it. > Ive been through my system so many times now that I understand the way > they work better than ever before, but i just dont get it.

You mean you don't have to pump when you're standing still???? In that case, I'd take the rear drums off and make sure all the hardware is in there right, especially the angled adjuster screw slots. Then look at the front rotors to see if they have big accumulations of rust in some places which might push the pads back as the lumps rotate past them. If this were the case, their might not be anything wrong with your hydraulics at all!!! > To make sure Im bleeding correctly....... bleeding procedure is as > follows: > > start with farthest from MC first, Right Rear: pump till pressure, > hold. open valve, close valve. release peddle. > > Left Rear, same > Front Right, same > Front Left, same Is that correct? At this point, I don't think the order matters. What matters is "Do you see air bubbles coming out?" I generally use an 18" hose into the bottom of a liter pop bottle. Run the hose all the way to the bottom of the bottle so the fluid that accumulates there will keep air from running back up the hose. Form a small upwards loop just outside the bleed valve so that bubbles will tend to drift away from the bleed valve. Just open the bleed valve and let the person at the pedal pump continuously. You will see that the fluid moves mostly outward with small inward bits as the pedal comes up. You only have to open the bleed valve 1/2 turn. Watch for bubbles. I don't think you are going to see any. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA *******************************
