Sticky Clutch Pedal after complete clutch replacement.

[Boxyowner]

Looking for your help? I just did a complete clutch replacement on my 2003 Boxster. After getting the engine and transmission in and completely bleeding the clutch hydraulics 3 time, my clutch pedal sticks after depressing especially at higher rpms. Did something else break in the process? Thank you for your responses.

Did you bleed the clutch with the pedal held to the floor?  If not, re-bleed it.

I followed Bentley's recommendation and press the clutch pedal all the way down prior to start of bleeding.

Clutch Disc

Release Bearing

Flywheel bolt

Clutch release bearing

Clutch release bearing O-ring

Pressure plate bolt

Clutch Slave

Ok, the reason I asked is that it sounds like you are pushing the pressure plate over center (turning the fingers inside out), which will cause the pedal to stick to the floor.

Are all the parts OEM or after market?

All are OEM

I am thinking of changing out the clutch master cylinder? Any thoughts.

A lot of expense and effort if it is not the source.  I would start by double checking the OEM part numbers against what Porsche lists.  You can use Sunset Porsche's online parts system to do this.

 

Was there any problem with the car's hydraulic system before you did the clutch?

When you bleed, did you make sure the brake fluid reservoir is full at all times and there's no air introduced into the hydraulic lines? In my '03 996, there's a separate partition for the clutch at the rear portion of the reservoir, which can run empty pretty easily if you don't keep an eye on it when bleeding the clutch.
