brake bleeding

[08cayenne]

my 2008 cayenne 3.6 has 254700 happy miles on it
and I just changed the rear rorors and break pads and because I had never bled the brakes I thought it would be a good idea so I tried to pressure bleed the brakes. I couldn't get much fluid to flow out and now I have no brake at all I've tried to pressure bleed again with no success. anybody have any suggestions

any pedal pressure? - any leakage on inside of wheels? - if you have a helper you could try the old school method - at least that would tell you if any fluid is getting down to wheel cylinders - if no leakage i'd say you have a LOT of air in the system - couldn't tell you what went wrong with the pressure bleeding - did you turn the caliper piston in when you compressed it?

[08cayenne]

I did, I have always changed my own brake pads and or rotors and I have always had a full solid brake pedal and because I had never bled or changed the brake fluid I decided this is the day; could I have damaged the master cylinder or should I continue trying to pressure bleed?

[08cayenne]

sorry but no; there is no peddle pressure and I have not seen any leakage at all

did you release the parking brake before bleeding? - put a hose on the bleeder valve and run it into a jar with some brake fluid in it - then open it while someone else presses the brake pedal - something should come out - air or fluid - i just read where you have to have someone else continuously pump the pedal slowly while the pressure bleeder is hooked to reservoir while you open the bleeder valves one at a time - did you do this? - sometimes just cracking that valve open isn't enough - you might have to open it a turn or two - i've never used a pressure bleeder so it's all new to me

i saw your post on the other thread - i wouldn't try the jack stand thing - did you try all the steps i suggested above? - what came out of the bleeder valve when you opened it and someone pumped brakes?

[08cayenne]

Yes I have tried to bleed with someone pumping the brake pedal but to no avail: without a diametric tool how else can I get the ABS to activate

[honerboys]

i'm not sure but i don't think the abs should stop the brake fluid from flowing to the calipers - so when you open the valves on the calipers and pump the brakes nothing comes out? - no fluid ..no air? - and the reservoir is full? - sounds like your master is not pushing fluid then - could it be full of air? - could you have pumped all the fluid out and replaced it with air? - i've never used a power bleeder so i can't advise you as to whether you did that right - how did you hook it up?
