Default Brake bleed questions & info needed

Well I replaced my calipers,lines and rotors. I bought pressure bleeder and got clean fluid and no bubbles at each caliper. I took out the master cylinder to clean out the reservoir. I loosened the fittings on the side to bleed it as well. With the engine off the pedal is pretty firm but with it running the pedal goes almost to the floor. I plan to bleed the system again but that failing will I have to take it to the dealer to do the ABS auto bleed? I was hopeing to avoid doing that more from a time stand point rather than financial. Unless they can do it on a saturday which I need to check on. I only pumped up the pressure bleeder to 10 psi do I need to do more? I bought the universal kit. It is not all that good of an attachment method. The thing slipped of the reservior twice, once causeing quite a mess. :mad Anyway did anyone on the forum have a similar experience? If so what did you do? Also the rotors I put on have a zinc plateing. Should I have scuffed it off or will the pads do the job. I drove it and did about 10 stops but the Zinc didnt all come off. I probably should have used the old pads as the dimpls and slots on the new rotors seem to be shaving the pads a bit. Thanks for any help :thumbs: One other thought. My car is a 2000. I am sure the fluid had never been changed. It was black and nasty looking in the reservoir. Do you think the rubber parts inside the master cylinder had deteriorated to the point where after I flushed it all out they dont seal properly anymore? I was going to rebuild it but there are no kits for it in the autoparts store. A new one is $174 delivered from fredbeans. Pretty pricey so I figured I would just change the fluid first. If I pump the brake the second pump gives a firmer pedal bly a bunch almost normal.

At this point you may want to try an old fashioned bleed where you have somebody at the pedal and you do the fittings. Make sure you get the sequence right which is RR LR RF LF if your car is a 2000 or earlier. I think you have an FRC? Use a hose long enough to keep the hose buried in some extra brake fluid fluid in a bottle so you won't suck in air if you don't quite get the stroke and you opening and closing the valve just right with your partner. Unless you ran the resivoir dry I seriously doubt you have air in the ABS.

One thing I really have grown to apprecite is the speedbleeder valves. They, virtually, assure you will get no air in the lines on a bleed and even allow one person to do it although I still like two so I can watch for bubbles and do a "safety check stroke" to make sure the valve is closed and nothing is leaking.

Good luck. Let us know what you find.
