It isn't too bad as long as you don't let the reservoir run dry while bleeding the slave.

You just gravity bleed...

Advance auto is also Western Auto in some spots. I think napa wants about $10-20 more for their slave over Advance even though they are both made by Perfection.

The suggestion to replace the entire slave is more a preventative measure an since you have everything apart it is a "might as well" type of thing.

If the slave you have now looks in great condition you could by all means continue using it.
