These can go bad sitting on someone's shelf, and there's little turnover in our parts these days, so I suspect there are a lot of these parts which have been sitting around for a long time. What brand was it? I agree that it is important to get the rear brakes adjusted at least somewhat before you try to bleed, but I've never seen the need to do any more than this. If you only replaced the MC, then you should find the brake feel to be the same as what it was, or better, when you started. I agree that if you have the front jacked way up, there may be a bubble in the MC that you can't bleed out. I've never noticed this, but I suppose it's possible. I think I've done lots of brake bleeding with the front jacked up. Bubbles in the lines will get pushed either up or downhill since the line is small. Bubbles in larger chambers are another matter. You should check under the floor mat near the pedal to make sure that the main line to the rear didn't break when you moved it. That wouldn't be at all uncommon on one of our old cars, and it would certainly explain your observation. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
