I just had the slave cylinder & the clutch on my 93 Si done.
The clutch pedal works fine, doesn't release pressure if held down & it returns by itself but it is really soft - I could probably push it in easily by hand - with my foot it has almost no "feel".
The mechanic said that this was because the master cylinder needed replacing but that doesn't seem right to me.
To me either the pressure plate, for some reason, requires less force to disengage the clutch (weaker?) or the mechanical advantage of the new slave cylinder is different which would cause a difference in where the friction point would be but the friction point is normal.

Is the mechanic right? If the master was in need of replacing it would be leaking & slowly re-engage the clutch even w/the pedal held down, no?

 

Bump - anyone?

 

this tends to happen a lot of the time when you change the clutch assy. Differences in the pressure plates number of finger cause the pedal feel to be harder or softer and oem replacements all seem to be a little different. You might just have to get use to the new feel of the clutch

 

yes, but loose enoug ht omove by hand is too loose, the only way to change mechanical advantage on the slave cylinder would be to make the release fork longer, which isnt gonna happen lol. I would make sure its fully bled, sometimes they can be a bitch to bleed, i had to do mine 3 separate times before i got it right.

okay, now that that is out of the way, does the clutch engage or not? when you turn the motor over, can you change gears while parked with the clutch in? thing im looking for is if the slave cylinder is actually disengaging the clutch, or if it is a leak in the MC. if the clutch doesnt disengage, you have two options, either there is air in the lines, or the MC is leaking, causing the clutch to not disengage, ensure everything else is right though, right release bearing and so forth were installed.

 

This is usally caused by not bleeding the air from the line properly...

 

Bleed the hell out of it an it sould fell nice to the foot.

 

i've always gravity bled my clutch m/c and slave with no probs. Then after a couple hundred miles, i'll crack the bleeder again to get any aire bubbles stuck taken out.

 

I never had a problem bleed the mc or the slave for that matter. but air in the lines can be the cause but since he had the shop do the clutch you would think they got it right...... or maybe not. just reread his post and they only changed the slave might be time for the master
