Brake Pedal Feel - Need some help, after bleeding ?? Its kinda soft. Options

[913B]

Is it suppose to feel hard on the first push. The pedal goes almost all the way down, then the 2nd and 3rd pump the pedal feels hard, but if I wait a few seconds the hard pedals goes away ?? Is this normal for an early 71 with 19mm MC or do I still have air in the system. I bleed it with the Motive Power bleeder and manual bleeding it with the speed bleeders. Is the problem with the speed bleeders ? I recently rebuilt all the calipers and install new lines, no leaks, but the MC is used though.

Let me know your experiences fellas ?

start at the bleeder closest to the MC. End at the bleeder farthest from the MC.

Other way around.

That "limey" up top is a typo.

You can "edit" your posts you know... (IMG:style_emoticons/default/confused24.gif)

No I did not bench bleed the MC. I installed it dry

Not a problem really.

I thought the power bleeder would do magic.

It should really... OK, let's go through a check list:

1. Bleed furthest to shortest distance.
2. Tap lines and calipers with a plastic mallet or the wooden handle of a standard hammer while you bleed.
3. Adjust the pedal clearance/master cylinder rod.
4. Make sure the venting clearance is adjusted to .004"
5. Get a decent pedal and bed the pads.
6. Bed the pads again.
7. Bed the pads again and drive the car.

What happens "VERY OFTEN" (as in, almost 100% of the time) with a new caliper rebuild is this; the new seals are aggressively pulling the pistons back off the pads and rotors. Even a small amount will cause a soft pedal feel. As you bed the pads, you will heat up the calipers and the seals and they will break in. As the seals brake in, your pedal will begin to come back up.

Follow this procedure:
