i just installed a new master cylinder and two new rear rubber brake lines.i hooked up my power bleeder.all wheels bled out fine however,i still have no brakes.i loosened the push rod adjusting nut so it is all the out (towards the front of the car).

From what I've seen discussed here, the way this system functions, power bleeders do not get the air out of them very well.. find some poor dude with big thighs and head for the right rear... Razz

I purchased the power bleeder because i usually work on this thing alone.I've never heard anything on the samba about power bleeders.

I have been around this car a half a dozen times bleeding out the brakes.And still pedal goes all the way to the floor.any ideas?

Adjust the push rod for about .040" play between it and the MC piston.

Single or dual circuit??

If that is a vacuum power bleeder, open the trash can and insert. Then invite a buddy over for some beers. Before providing the beers have your friend help you bleed the brakes.

I installed a new single circut ms.the power bleeder is a pro motive bleeder.It looks like a weed sprayer.To adjust the push rod ,how do i know when the rod is pushing on the ms?Currently there is no resistance on the pedal.

Is the power bleeder a vacuum or pressure type???

Turn push rod to rear a bit. Grab the rod with pedal in full back position. Should be able to wiggle push rod a little up and down when rod tip not in touch from the MC piston. If you have wiggle move the brake pedal by hand a little till rod is not wiggable. Then move pedal back and note at push rod how much play.

Did you adjust the brake stars for a bit of brake drag at each wheel??

Bleeder is a pressure type bleeder.Should i have a bit of brake drag @ each wheel?

Yes, you need a bit of drag so each shoes does not move about when trying to push the brake fluid.

adjust the brakes and do a manual bleed! Grab a friend, neighbor, parent, sibling and do a manual bleed for crying out loud. Power bleeders suck on these old things and are hit and miss.

ok!I have tried the manual pump the pedal a bunch of times hold then open the bleeder and on to the next one method.I also hooked the power bleeder to the reservior,then hooked the power bleeder directly to the bleeder at each wheel.still no brake pedal.

I bought a motiv power bleeder too...didn't work. What did work was a buddy at the bleeder nut and me at the pedal. The key is to make sure the brakes are adjusted properly.

You shouldn't even be thinking about bleeding your brakes unless they are first properly adjusted.
