Are the piston bore diameters the same on the clutch master cylinder for the Civic and the Integra? I am using a Civic clutch master cylinder with an Integra slave cylinder and am not getting the performance I'd like out of my clutch. It seems to grab lower than expected. I tried looking around but none of the posts I've read specify which master/slave combo I should be using for optimum performance. Any input would be appreciated, whether it be opinion or fact. Thanks again.

 

Upon further research, some of my parts guys are telling me that the bore would be different (Specifically in the GSR) and I would probably need to get a GSR master/GSR slave combo in order to get good operation. Any other opinions would be accepted and hopefully someone else will find this information useful to them too.

 

From what I know, the cylinder bore doesn't make a difference... Fluids don't expand, hydraulic physics... Just some clutches tend to grad earlier than others... It has nothing to do with your master/slave cylinder combo.

 

Thanks for your input but I actually disagree. Wouldn't the bore size in the master would determine how far my slave gets pushed out? Thus having an effect on where my clutch grabs, if I'm correct. But then again this is all theory based off of my personal knowledge. I may be incorrect.

 

i would leave you slave and master alone. bleed your cluth, and flush it with new fluid. if the pedal still contues to be low, then adjust it up using the threaded adj rod on the clutch pedal.

 

I'm sorry, I hadn't been clear. I've already bled the system throughly (both at the master and slave) and adjusted the pedal to proper height. It is where the clutch is grabbing, not the pedal height, that's the problem. I wouldn't even really call it a problem. It's just not "normal" to me.

No, it doesn't because you have the same amount of pedal:piston travel, if you were to measure the distance beetween the springs on the pressure plate on your clutch, there would be the diff.

 

Interesting. I'll be sure to look deeper into the concept as a whole. Thanks for your input. I appreciate it.

 

no prob.
