The brakes on Itchy (my '71 Series 2a 109) were a bit soft so I thought I would give 'em a bleed before the MOT (along with a multitude of other little jobs AND changing the timing chain, more on that elsewhere later).
I invested in a Sealey kit as I haven't got offspring / an other half to help pressing the pedal.
Started on rear PS and it was really bubbly, bled it until the brake fluid came through clear and it was still bubbling. It was then that I took the rear DS brake drum off and realised the wheel cylinder was leaking. Replacement ordered and fitted (along wiv a braded hose, might as well add a shiny but while I'm at it) this morning but still bubbly.
I thought I would try starting from front DS to see if it made a difference, sucked the mucky stuff through and that's bubbling too.
Reckon that must be the master cylinder gone, but there's no sign of any fluid escaping around there or by the pedal. Could it be letting air in but not fluid out..? And it looks like you have to take the pipe from the reservoir off to get to the inspection cover screw, which is a bit of a pita to say the least!
