You really should connect all the lines up exactly the way they came off. Normally this won't make any difference, but in a failure the braking could be L/R unbalanced if you swapped things around. The ports on the front of the MC are for the front brakes and the rear ports should feed the rear circuit. If you replaced your 70 MC then it is likely that you need a new steel line for the LF brake because the new MC has different ports. The switches go on the left side. If you aren't getting fluid out, loosen line fittings one at a time and bleed to that point to get started. You may find that you can bleed just fine up the start of the hoses but nothing will come out of the other side of the hoses. In this case you probably have hoses which have deteriorated in the inside and have become blocked. This is unfortunately common these days and these hoses can only be replaced. - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
