I got the powerbleeder from 928Spec last week.
I have an AX on Sunday - so I decided to go ahed and flush and bleed and go ahead and put the AX wheels/tires on.

WOW - A one man job - SOOOO EASY - And did it in lesst than 45 minutes!!

At $39 - this is a MUST HAVE!

 

I prefer the vacuum method, but either is a blessing.

 

The power-bleeder definately rocks. I alternate between blue and gold fluid.

 

Question.

When replacing the master cylinder and then using the power bleeder, is it still necessary to bench bleed the master cylinder?

 

I've tried vacuum, brake pedal, and power bleeder. In my opinion nothing beats the power bleeder. One person operation, no need to constantly refill the reservoir. Easily done in 1/2 the time of vacuum bleeding. Unless you are using the fancy speed bleed screws with the vacuum bleeder it is difficult to tell when all of the air is out since air is always being sucked through the screw threads.
