[A4] Clutch Woes - Round 3

[Richard Andrews]

I use the pressure bleeder in conjunction with standard bleeding techniques
on clutch systems.
10psi should be sufficient. pump up the reservoir, then pump the pedal with
the bleeder closed, then with an
assistant, open the bleeder, and have them SLOWLY press the pedal down.
when the beyond half way on the travel, close the bleeder. then pull the
pedal up and pump it several times before repeating the procedure above.

I would do this several times like 10x at least.

This should give you good results.
