brake bleeding

[Kneale Brownson]

Audi recommends pressure bleeding (I use the
Eezibleed:  http://www.rdent.com/pages/tools.html).  When you do a two-man
brake bleeding by having one person pump the pedal and hold it while the
other opens and then closes the bleeder, there's a possibility of pushing
the pedal beyond its normal travel, and therefore, moving the piston in the
master cylinder beyond its normal travel.  It's possible the bore of the MC
can have corrosion/debris in those areas outside the normal amount of
travel for the piston,  which might lead to hastening the demise of the
seals on the piston.
