Like muel says...the pawls are probably stuck down with too much grease. Flush it through with WD or similar solvent then lube with a thin oil.
If all else fails, tarty will, I'm sure, help you out
Nah, the reservoir is there to have a tiny bit of air inside...this air will just enter the system if ran upside down. So...its new lever ( or just body) or run your brake's Euro I'm afraid
That adaptor effectively gives you a 185 rear brake...or a 205 front. You'll need to downsize your adaptor to a 185 front....or buy a 203mm rotor and take a washer out.
Nah you don;t want any form of lubrication when two components are relying on an interference fit. There may be some kind of paste you could use though to help stop against the bi metal fusion ( not sure if thats only with ally and steel though? ).
I think theyre discontinued dude...
That one above looks horrible tiny...lower front end than I run on my +40 Coust and kind of freakish with the angle of the stays to the ground
