Bleeding master cylinder.

I am going to use a power bleeder to bleed my brake system after replacing my master cylinder.

Do I still need to bench bleed the master cylinder, or will the power bleeder take care of it?

I don't mind flushing my entire system. It probably needs it anyhow.

Thanks.

You really should bench bleed the master cylinder before you install it, it probably saves time, and you're more sure of the job. I'm assuming you already know how to do the job?

Vacuum bleeding will probably take care of it, and pressure bleeding should take care of it, but the years have made me paranoid, and I like to be sure.
