so, I'll start off by saying I'm fairly new to the honda scene, furthermore this is the first manual car I've driven.

so I've replaced both master and slave cylinders for the hydraulic clutch line and have bled the system multiple times, based off multiple posts here. I've done it by myself and with a friend, not sure if to the tee or not, but I've gotten good pressure built up and gravity bled prior to manually bleeding it(redundancy is always a sure fire way to make sure it's done right, right?), but I keep noticing a really odd trend. After I get really good pressure built up, if I were to put my hand on it slowly, as you would if you were driving, the pressure I had built up is totally lost and depresses to the floor. What gets even more odd is when I slam my hand down on the clutch pedal again, the clutch slave moves and the mechanical arm sticking outside the transmission will move and I can put it in gear. So it's like there's only pressure built up at the time I exert a good amount of force on the pedal and that's maybe with a 60 percent success rate. Does anyone have any ideas on what that might be?

 

Either a fluid leak, or your new master cylinder is a dud. Chain store, I assume?

 

Or you have leak/cut in the line somewhere.

 

It was a chain store, unfortunately... any brands I can trust if this is the case?

 

And also, I've inspected the line several times, and no visible leaks.. I mean, it's a hard line so it would be very apparent if that was the case right?

 

You would know when there's a leak because the fluid level would go down in the reservoir. Suggest trying another MC.

 

Return both parts you bought.

Oem brand. I use exedy on my civic and integra.

 

So internal leaks on these MC's are fairly common from chain stores? I take it?

 

That beats the #@&! out of the prices I just paid for OEM...
