Power Bleeder - Why you need this tool

[tmontague]

Yes, once the bleeder is cracked open you can fairly easily push the SC piston back into itself and hold it there.

Your SC is likely fine and just needs to be bled. Typically when a SC goes bad they will leak and/or not disengage the clutch properly. They are not a common wear part on the Yaris to my knowledge.

Some cars need constant bleeding, the Z06 corvette is no exception, track time on that car leads to constant bleeds as the fluid become dirty quickly and clutch feel degrades. The Yaris isn't as sensitive and the fluid typically doesn't become dirty but I find a SC bleed every few weeks of you're at the track it every year of you just DD will do a lot for clutch feel.
