Problems with clutch master and slave cylinders

Hi all,

I have purchased these slave and master cylinders new quite a while ago for my project. Now that finally everything is in the car I was unable to have the clutch operate.

I have bleeded the clutch following the procedure described in the w/shop manual via the right front brake calliper. I was able to have fluid go backwards in all the circuitry and fill the small reservoir. But the clutch pedal kept going down with no resistance and the clutch was not operating.

I took both master and slave cylinders out. The piston in the slave cylinder is quite sticky and the spring is not able to push the piston back. I took it apart and all seems in good condition. The bore is not pitted and the seals look supple and not damaged. But still, it's sticky when I put everything back together with brake fluid.

The piston of the slave cylinder is all the way inwards and I have no idea how to get it out. The bore is not pitted, I had it soak the whole night in some WD40 and then tried to bang the slave cylinder on a piece of wood to have the piston come down to no avail.

I have no idea how to solve this. Any help would be greatly appreciated.

Thanks in advance!
