I haven't used my m3w much in over a year but it was stored without the hand brake being engaged & moved every month a few inches forward & back.this past November i drained some of the brake fluid & topped it off with some new oil. Just now I noticed its heavy to push around, I did bleed out all the old oil & all is fine now.
Q8, I hope you're just using the word "oil" as a generic term for the correct DOT spec'd brake fluid. OIL of course would be a BIG no no...
