I'm running a heavy pressure plate in my Accord, and after 10-15 min of continuous shifting when I get around traffic lights, my clutch doesn't disengage as well as it should and shifting becomes difficult without double clutching between gears.

I don't have any leaks, but either heat or stress on the master/slave cylinders from the heavy pressure gradually appears to lessen their ability to fully disengage the clutch disc.

Some of you out there are running heavy pressure plates as well, so how do you mitigate this issue? Swap out master/slave cylinders annually? Run a twin-disc setup? Maybe the short length of soft line becomes a weak point after some use? Give me some ideas!

Are you running a factory line/dampener setup or a stainless line?

I don't recall from your build thread.

AFAccord

Stock master, line, and slave. There's no point to replacing the whole hard-line, but I don't know whether that short rubber section is giving me the issue, or if it's the master/slave cylinders themselves.

Although it isn't anything too heavy duty, I have an Exedy stage one organic clutch in my Accord and with the B&R stainless line AND a shot master cylinder it still engages wonderfully. Do you know if the 6th gens came with clutch dampeners on the OEM hardlines?

AFAccord

I'm using an ACT XT pressure plate. It's not the heaviest one I've driven, and it's also not the first pressure plate to give me pedal problems. Don't know about the dampeners, though from my memory, it's straight line all the way. 6th gen lines aren't detachable like some of the other generation accords and preludes. I'd have to custom make a braided line to replace the flex portion.

Some companies actually make the rubber section in stainless just for replacement. Unless its literally a sold line to the rubber, no fittings involved where they connect.

AFAccord

Yeah, it's strictly a crimp connect, no fittings at all.

What fluid are you using? It could be due to boiling.

I'm almost certain I used the same DOT 4 that I used when I flushed the brakes last year. Then again, I don't remember disconnecting the slave cylinder during my build, so it may still have old fluid in there. I don't think the clutch system is subject to the same heat as the brakes though.
