I have struggled bleeding my clutch slave cylinder after a total engine rebuild. I have tried manual, vacuum, and pressure bleeding, yet still I only get 1/2 pedal pressure.

When manual bleeding, my helper held the pedal to the floor while I opened then closed the bleed valve. I didn't get air, just pure fluid.

I then added a pressure bleeder onto the reservoir and pressurized to around .75 bar. Again, holding the pedal to the floor, opening then closing, yielded no air. With the system pressurized, the pedal felt great! It was stiff all the way to the top, returned on its own, and I could feel the slave cylinder actuating the release fork from under the car. Once pressure was removed, the slop returned.

Does this sound like the master cylinder? I'm not sure what those symptoms would look like.

The only other change to this system is the hose from the slave cylinder to chassis tube was rebuilt by Amazon Hose with steel braided. I can't imagine the hose volume would change??

Anyone else experienced this or have suggestions?
