If I change clutch MC it'd be my 3rd. But I've been through 3 sets of rear bearings, 2 fronts, 2 sets of 4 spindles, 2 MC brake... lolll A clutch MC is not expensive. I'll troubleshoot a little more and if I can't work it out I'll get a new one.
Bob shortening the rod should put less pressure on the fluid then? You really mean the rod in the MC that attaches to the pedal box and pushes onto the diaphragme of the MC?
The MC is pumping fluid through the output hole, but I don't know if it does it as designed.
I cannot pump fluid through the line, cuz it pumps a few inches out and takes it back in, if the hard line is empty (which it is), then the fluid moves a few inches in and then back in the MC.
Pumping by hand is a good idea to test.
The vacuum bleeder didn't help.
The slave is attached at the bottom of the gearbox, say at the same level as the X bars on the rear gearbox support, I'd need to either raise the gearbox and engine by 2 feet or lower by 2 feet the MC. Not sure I follow you I this test?
Maybe I could test by removing the line at the slave and pumping air out?
Axles, DSS does not know why it's different than ours, but they do know it fits on the same spindle assembly as we checked our spindles and they have the same measurements. Since they sold more than 1 sets of their Level 5 CVs to 2002-2007 WRXs and they never complained, I then believe I'm missing something. DSS asked me to try removing the inner seal #2 and see what happens. I wonder the consequences of removing that seal, though. Dust, dirt, etc. And if other owners did that or not. I think the DSS guy doesn't know how the seals are installed on the Subaru. I believe they did it once when they designed the part and since it worked they never retest it. Which makes sense.
If that doesn't work, I may send off my assemby to them to figure out.
