[Spridgets] Brake Master Cylinder

[Glen Byrns]

Its for retaining a bit of residual pressure so the brake shoe return 
springs don't fully retract the shoes causing you to have to pump up to get 
brake action each time.  Its also helps for solo bleeding.  HOWEVER!!! It 
has less function in a disc brake car and will cause the front discs to 
constantly rub a bit too much and wear out the pads pretty fast.  Disc brake 
conversions require you to punch a small hole in the rubber cup to mitigate 
the effect.
