Another Brake Hangup

[Supersport396]

So my front brake is dragging and taking a test drive locally I was lucky to get home. If I crack the bleeders it rolls free so I'm sure it's the splooge valve. It will happen again in short order. My worry is I can't seem to get the reservoir off without possibly destroying it and or being able to get a correct o ring let alone reinstalling it. I have this type, not the one that came on it with the pull back bars (1980).

Is there a replacement master I can get that isn't junk?

You don't need to remove the nylon reservoir bowl to clean the spooge hole.

Just find the tiny (smaller) hole in he bottom of the reservoir and push a fine wire through it.

If after you clean out the spooge hole and you still have brake drag you may have to clean under your caliper piston seals.
