I think what is humorous is the statement in the workshop manual that says:
"Gently move the piston up and down in the cylinder bore to free the nylon
guide bearing..." That might work on a brand new assembly. Out of five
master cylinders I have recently disassembled, only one nylon bearing (the
one out of my Midget) came out relatively easily. I had to drill/chisel
the other four guide bearings out after soaking in penetrating oil for
almost a month and rapping, rapping, rapping, didn't budge them.
One interesting problem I have run into on one of these: all the retaining
circlips, washers, etc. are out of the cylinder, but the piston refuses to
come out. The outer piston moves freely, but the inner one is stuck solid.
Penetrating oil and air pressure haven't moved it. Any ideas?
