Hello from Atlanta GA.  My daily driver '81 has mysteriously lost brake fluid over the past week.  I found a leaky clutch slave cylinder, and therefore replaced both master and slave, bled clutch, and all seemed fine.  Today however I noted a clutch judder, checked the brake fluid reservoir, and discovered that I again had an almost empty brake fluid reservoir.  Careful inspection of the clutch and brake lines, drums and calipers showed no fluid loss/wet areas.  The brake m/c is one year old Busdepot unit, servo unit original.  Questions--  should I replace both brake M/C and servo?  Remanufactured units OK, or should I only go with new more expensive Busdepot or Vanagain.com units?  Is the servo unit replacement the job from Hades---R&R dash, heater controls, instrument panel...?  Any short cuts to replacement? How long should this job take someone who does all of his own van work?  Anything else that I should do whilst I have the dash off the van?  Thanks!

Regards,

Michael and Christina Nichols
