wondered for few weeks why this plastic cover on this non-abs k11 master cylinder won't unclip off easily.
since I'll now be using this primera MC andy gave me, let's do some destructive exploration eh 
snapped the clips off

eventually it nudged off and yep it was abit of corrosion n o-ring keeping it stuck on

so here's the primary stage on the piston

slight rust outside the o-ring seal

and now the new MC off a P11 2.0L primera andy gave me. this only has 2-ports so will have to completely re-do the entire brake lines to have one circuit for the fronts removing the ABS unit and then another circuit going to the rear removing the stock bias compensator and will prob have to fit a manual bias adjuster. not a small job

lets look inside

remove circlip

used a tap to pull the piston out

looks alright, can't get the 2nd piston out n dare not disturb it so just reassemble.
a rough camparison in the engine bay and notice there's gonna be a big issue with the massive MC potentially fouling the fuel reg in the modified sr20 rails :/
so the rail or reg may need modifying/remounting?
