After replacing the CMC and CSC been having this problem. Clutch pedal is fine when i am driving in town. Then when i get on the freeway it loses pressure a little bit, but still have some pressure to push the clutch and shift gears. Then when i get back into town and use the clutch pedal more it is perfectly fine.

I check all the lines and the fittings that go into the CMC and CSC when i first did it, I did NOT tigthen them all the way good. Then i rechecked and tightened them, now the fittings are COMPLETELY dry. Is it possible i still have air in the system? I mean i bled it so many times... its now pissing me off.

And i replaced the hose from the clutch reservoir to the CMC

Let the car sit for a few hours, then re-bleed the clutch. When you bleed the clutch, don't pump the pedal. Press it down 1x only each time you open the bleeder.

ok ty will try again

 

Problem fixed. Turned our the Duralast CMC was trash. It wasnt holding pressure. Changed to a new CMC not duralast and OEM slave. Brand new again
