Questions about bleeding brakes
 

After flushing through the system with a power bleeder, my pedal seems soft. I have been told to finish bleeding the system by pumping the brake as I bleed. Do I just open the bleed valve while the brake pedal is pressed down hard or do I have someone pump the pedal in and out? Also, will I have to worry about watching the reservoir or will filling it up between bleeds be enough?

1) Pump pedal 5 to 6 times, then push pedal hard and hold, open vaule on caliber and when fluid stops, close value.
2)Pedal should be on the floor now and lift your foot off the pedal after the value is closed.
3) go to 1
4) Check fluid level after two or three cycles of doing 1
5) Start bleading from farest caliber and work to nearest one

Bill is correct. The only thing I would change is to close the bleed valve BEFORE the stream stops flowing to prevent any air from flowing back into the caliper.
This does require 2 people to do the job.
A power bleeder should allow you to do the job by yourself. YOu have to make sure your not allowing the power bleeder to get air in it. and you bleed from the farthest to the closest to the master cylinder.

To manually do it, I do the following with my Son, Daughter or Wife I haven't been able to teach the doq how to do this.

I call "press"
He/She/Goddess/Dog still won't do it, presses the pedal.
I open the bleed screw and then close it before the fluid stops.
I say "cycle"
The "operator" releases the pedal and then presses and holds the pedal.
I then open and close the bleed screw as above.

The pedal will move down as you alow the fluid to come out.
After a couple of cyles of this check the fluid level in the reservoir
Check it carefully the rear reservoir is hard to see.
I do the bleeding untill all dirt and air is gone.

A couple of points: Park on a level surface or have the front of the car a little higher. This will insure that new fluid will fill the rear chamber of the brake fluid reservoir. Also be gentle with the bleeder valves.
