Ok, how does the master cylinder come apart? I need to get the plunger out of the thing, and I can't figure it out. I know it comes apart because honda sells the rebuild kit for it. The question is how to get it apart?

I no longer have a manual (went with the bike) but my recollection is that the resevoir prys off, then there is a circlip in the hole under that. The circlip is really hard to get out because of all the old gunk you'll find under there.



Somebody correct me if my memory is shady.

Take the lever off. Once the lever is off there is a snap ring inside around the piston, it is a real pain to get to but once you get that off it all comes out. You might have to pry it out but it will come out.

Well, i have concluded that this master cylinder is NOT like the one in my manual, not even remotely. the one in the manual is NOTHING like the one i have, and the one on the honda parts fiche is a little closer to the one i have, but still isnt "it"....i have no clue how this thing comes apart. no clips or anything anywhere

Got a picture of your mc so we can tell you. I looked on the monster project but there wasn't a right view.

never mund. the c-clip was on the face of the plunger underneath the rubber boot that protects the plunger. unfortunately, this brake master cylinder is NOT from this bike as far as i can tell, so getting a rebuild kit in the future wont be very possible......and to think i'm having this part Chromed

This doesnt appear to be for this bike, according to the manual or the parts fiche. If someone knows something, Holler! Thanks!

As long as you're at it can you measure the MC piston length and width in millimeters. It resembles one I have seen before. But really the only part in question would be the piston width to replace the rubber on it.
