Prior owner was honest man and I've got a receipt for a master cylinder rebuild kit so I've no doubt that he rebuilt it in the last six months.
Today while tearing down in preparation for repaint/restore I notice so brake fluid on the frame near the rear of master cylinder. (not completely sure its not seeping from reservoir)
Anyway, make the decision to take off the master cylinder, caliper, etc. so I can set it aside to eval and when I disconnect the rubber hose from the brake hard line the expected brake fluid comes out but so does all of the fluid in the MC reservoir. Am I nuts in thinking that I should have only had the fluid in the lines drain and not the entire reservoir? I've done tons of car/truck and motorcycle brake jobs over the years but I've never seen this happen. The brake cable was disconnected so there was no "tension" on the master cyl.
Trying to figure out what my next steps are. From the frame corrosion its obvious that leaking brake fluid is a long standing problem, and I'm hesitant to rebuild it AGAIN in the hope that it would fix it.
Any advice gratefully accepted.
Have a good one,
