<VV> brakes - a word of caution

[Matt Nall]

   Upon disassembly, the mystery was solved.  The backing plate and everything 
inside the drum were still clean and bone dry.  Not a hint of wetness.  This, 
after a few thousand miles of travel.  So it appears that dot 5 brake fluid will 
seep on a car that has sat unused for an extended period of time.  In my case it 
was 19 months.

===========================================================


  Randy... ALL  Drum brake systems have a 10 psi  "Residual pressure valve"  to counteract the springs on the Shoes and keep pressure on the CUPS!!


No seal is "perfect".. after months of NO USE  that pressure is dissipated... and ANY FLUID can / will SEEP..


note:   On Disc  systems.. a  2 psi  Residual Valve   is only needed if the  MC  is below the Caliper / s
