Help please: MC and bleed problems

[flaatr@yahoo.com (Euroroc II)]

If this is on you 16V (I assume) then the MC has 4 spigots on it... One set 
goes to the right front and left rear and the other to the left front and 
right rear, dual diagonal blah, blah, blah. The two lines going to the back 
should have proportioning valves, one for each.

Where is the fluid going? I don't know. Pull the MC off and look to see 
that it's not leaking into the booster, never seen that happen but it's a 
thought. If all is ok in there fill and bleed again always starting at the 
farthest rear wheel from the MC and working your way to the front closest.

I can't offer any more help at this point but I can give you this advise, 
don't listen to your parents!
