Clutch Pressure Accumulator Replacement

[jporter]

I’m a new 01 turbo owner – used to have a 98 Boxster. My first work on the turbo was to change the clutch pressure accumulator this past weekend because of a very hard pedal at startup. This was a straight forward procedure and I spent most of my time trying to find the proper size/shape wrench to tighten the new accumulator to the slave cylinder. This fixed the hard pedal at startup and also improved the shift from 1^st to 2^nd that used to be unpredictable. The question I have concerns the bleeding procedure.

I initially thought that I would have to bleed the system using the bleeder valve on the slave cylinder. The repair manual seemed to imply that this was not necessary. The manual says “Bleed clutch high−pressure hydraulic system. To this purpose, depress the clutch pedal approx. 10 times”. I bled the system by pumping the pedal several times and put new fluid in the reservoir for the steering pump in the engine bay to keep fluid up to the proper amount. This worked and as I said the clutch works great. My assumption is that the bleeder valve on the slave cylinder only applies to the low pressure side (pedal side) of the system. Does anyone know if this is a correct assumption?

You are correct, the high pressure circuit is powered by the steering pump (as assistance) and used the PENTOSIN fluid from the reservoir on the pump. The low pressure circuit use the same PENTOSIN fluid (IMPORTANT!!!) that are contained in a reservoir under the black trim, below the front windshield, left side of the car, and be bleed on the slave cylinder.

RFM, Thanks for the reply and the great support on this site.
