The Mrs has a 1986 Mini Mayfair 998cc which started leaking fluid from the master cylinder reservoir (yellow tag type) and eventually lost pedal pressure completely. I've just replaced the master cylinder with the replacement from Mini Spares (here: https://www.minispar...sic/GMC227.aspx), and set about bleeding the brakes.
Started in the usual order from rear passenger, to rear drivers to front passenger to front drivers, but I'm not getting any fluid out of the rear passenger, and a very minimal amount from the rear drivers. Just to rule out a dodgy master cylinder, I bled the fronts and got what I'd call the correct amount of fluid through from them.
I'm a bit stuck as to where to go from here - the handbrake works fine, and there's not evidence of fluid around the bleed nipples or casing of the rear drums. My next thought is to whip off the rear drums and have a look if there are any leaks on the cylinder within the drum, but not sure if there are any other valves which may have failed? Otherwise I was thinking of asking the garage to pressure bleed it in case there's an air lock (if that's possible?)
Appreciate any pointers!
