So I got the MC taken apart, cleaned the chunked up old fluid (it's been sitting since at least 78) and put it back together. Problem is it won't pressurize or pump fluid. The spring is pushing the piston out very slowly back to the brake lever.
I'm pretty sure I put it back together the way it came apart but this is puzzling me. I do have manuals and have the rubber seals pointing in the correct direction including the one on the piston pushed up past the shoulder. I also have cleaned all the little port holes in the cup at the end of the spring and behind the reed valve at the end of the piston. The return hole is clean and open as well.
I can take a pic of the assembly as I have it but the rubber seal at the spring end is a pia to get back in.
Where am I off? Thanks
