Had the brake master cylinder fluid pipe bolts soaking for a week and no movement… so in 30 seconds I nipped through the pipes with pliers and out came the master cylinder. The casing was as filthy and with surface corrosion much like the clutch master but this one hadn’t nearly dried out!
The push rod was seized too and no worse than the clutch mechanism, infact it was probably better as the piston came out easier. All looked fairly good, even the seals looked unworn. Just have added new brake piping to the list of parts, now do I go for copper or cunifer (a mix of nickel and copper).
