did you buy a new brass sleeved 13/16" MC and the 13/16" seals at the same time?   I wonder if we both got 3/4 seals by mistake??

I hope Miles or Mike will ring in on the leaking MC.  Mike rebuilt mine and I know both know a lot and have been around here for a long time so maybe they can help out.

Yes for 2 out of the 4 seals you unscrew it. 1 is on the very end and The very last seal though has to be pulled over the larger portion of the piston
This is how mine was atleast. The books I have online didn't add much help.

Hey sorry I was at the movies, I still need to read all the emails and get caught up and I will take a look at the MC when I get home and give you the size. I replaced everything. The whole braking system is new or rebuilt how ever you want to say it. I believe it's the 3/4 MC, I will check when I get home tonight.

Eric;
Who did the brass sleeving?
And, you can do a bench bleed to see if the master is working just by attaching the reservoir to the master and holding your fingers over the outlets.  I'm not aware of more than one piston set for the 13/16 master, but the 3/4 master has three different end pistons and without the correct width for the seal there can be all kinds of problems.
I normally clean the cylinders with lacquer thinner after cleaning and then lube the seals with brake cylinder assembly lube.  Also cleaning all the lines with denatured alcohol will protect everything from contamination.
I have gotten seals from different sources and what Miles sells is the best bet.   You also have to understand that check valve for the rear has larger and fewer holes that the front check valve.  Also one has a rubber spacer and the other a metal washer.  Because the seal has to seal around the piston and the cylinder there are all kinds of issues even causing them to be cut on a sharp non-flush brass sleeve or bleed back hole not de-burred .  Clean is all important with brakes but bad parts or good part being sold by some one who does not do their home work can be just as devastating.

Re: leaking master cylinder

Post by Eric Geiger »

Everything was purchased through Bruce online at
honda600carparts.com .
The kit came with 2 new check valves but both were identical.  I used my plastic washer from the original cylinder along with the new springs supplied for one and a supplied metal washer for the other.
It will build pressure but always would leak before enough would build causing us to stop bleeding the system and pull the master back out.
I've been in contact with Bruce
