- No real disagreement but two more points: (1) If the fluid disappeared
- but the pedal wasn't feeling bad before the fluid was gone, the slave
- cylinder is more likely than the master cylinder. Not only that, its a
- lot easier to get to and replace! Look for leakage there, where it is
- mounted to a flange on the transmission bell housing casting. (2)
- While you can bleed it, the Corolla I had (I replaced the slave
- cylinder twice, never had a master cylinder problem, which is a slight
- statistical reason for point (1) as well...) would bleed itself if
- you just pumped the pedal up and down a lot. A hydraulic clutch differs
- from the brakes in degree: The clutch slave cylinder moves a long way
- each time you push the pedal, when compared to brake calipers or wheel
- cylinders, so a greater volume of fluid moves up and down the line.
- Apparently this can eventually get the bubbles back up through the
- master cylinder and out, at least it worked on that Corolla.
