2005 JCW 64000 miles. My son's car. ABS light popped on then car got progressively harder to shift. Pumping clutch pedal gets the shift full into gate. My thoughts are master or slave sucking air. No indication of fluid leaks at the slave end of system. Any thoughts or experiences out there? Should I just replace both? Feeling the throw of the slave it seems short but As my own JCW is apart on a blown engine removal I have no gauge. Any help appreciated. Thanks, Scott
