Can't get clutch to pump up like it should. What to do?

[sdt354]

I've always had issues with bleeding clutch systems. The trick that I figured out (at least it works for me) is to remove the slave cylinder from the engine and clamp the piston with a C-clamp as if you were trying to push it back in like a brake piston. Then hand bleed like normal. The clamp helps build the pressure in the line quicker since you have something solid like the clamp to push rather than the clutch spring that compresses a little.

Just my $0.02.

Doug, you might have something there. Or loosen the bolts and let the piston out, and when done bleeding crack the bleeder and re-tighten the bolts to get out the last bit of air. Never tried it, just thinking outside the box.
