Clutch pedal effort change

[royp4]

This is a rather strange occurrence. I have a 2003 Carrera Cabrio 996. After normal acceleration, the clutch pedal requires what I consider to be normal effort to depress. After running up to 6000 rpm when accelerating, the clutch pedal effort decreases somewhat. I have not detected any sign of clutch slippage or any other abnormality. My question is whether this is common, and whether it is an indicator of some undetected problem. I failed to mention that after a few minutes the pedal effort reverts to normal. Thank you in advance for any advice on this baffling occurrence.

While I can honestly say I have not personally encountered what you are describing, normally when a clutch in one of these cars is on its way out, the pedal effort increases, not decreases.  When was the last time your brake and clutch hydraulics were flushed?

Is there an accumulator on this model or is that only on the Turbo models?

The 996 does not have a clutch accumulator, which is just above the clutch slave on the turbo (black ball like device in photo):

Clutch and brake systems flushed and refilled 2/9/15 by dealership. I had noticed this occurrence both before and after the service. Just wonder if I should be concerned, and trying to understand what could cause this. Thank you for your time.

Any changes in pedal effort is reason for concern.  How many miles on the clutch?

[royp4]

Clutch is original and just turned 80,000 miles. No sign of slippage or noise. Only occurrence is the temporary change in pedal force seen only after winding engine to 6000 rpm or so. Perplexing!

80K is a better than average life for the clutch, so it may be approaching its time.

JFP I'm afraid you're right but don't really want to believe it. I think I'm going to continue driving and be alert for any further anomalies. Thank you for your input.
