Reply to "clutch adjustment"

I'm not sure what the normal pressure in the system is, but I would guess around 450 to 500 PSI. It depends upon the ratio of the master cyl and slave cyl bores, the pressure plate spring rate, and how quickly you depress (or stomp) the clutch pedal.

The Aeroquip FC332-04 hose has a fair amount of elasticity, has a max 250 PSI rating (you knew that), has a max temp of 300*F, and is not approved for impact hydraulic applications. Stomping the clutch during a fast shift could be construed as an impact application (kind of). If it were my car, I would get rid of the rubber hose and use the ss braided teflon hose. Besides, the ss line looks much better than a hose (even if the hose is blue!?) IMHO.

This all assumes (fatal error) that the clutch master and slave are functioning properly and free of air.

Other possibilities would be if the clutch pedal is not returning fully (broken spring?), the clutch master cyl push rod is too long, or the master cyl is by-passing.
