Need some help on brake pressure accumulators

[zak_62]

Hi. I need to replace the pressure accumulator on my 964, but I have never worked on a system with pressurized accumulator before. Is there any difference in the procedure in comparing to the standard vaccuum boosted system? Should the pressure accumulator also be bleeded?
Thanks
Isaac

The system is very different from the vac booster. Pressures are a lot higher in the accumulator. There is a specific bleed sequence and also a fill sequence for replacing the accumulator. I would suggest you get hold of the factory manual for the detailed instructions or someone may be able to post them up.
