The ABS accumulator on my '96 GS-R is leaking. I searched and saw where there is an o-ring that fails when this happens. My question is how difficult is it to remove the accumulator? There is a bolt on top of the unit, is this what holds it in place or are there other bolts on the bottom? How much fluid does the accumulator hold? Can the fluid be removed other than pouring out when the accumulator is removed? Any help would be greatly appreciated.
