Brake problems

[neillewis]

Help! My 1981 Morini 500 has a dodgy front (RH) brake caliper. The pistons were seized so I applied heat to free them successfully but when put back on the bike they now leak fluid. I believe there are seals in the caliper which may have unsealed as a result of the heat. I urgently need advice on this. I've tried to source a replacement seal kit and a replacement caliper to no avail. I also need replacement bleed nipples but can't find those either. Can anyone please help me out here?

Fraction of a minute on Fleabay turned up 30 or 32mm piston dia. seal kits. Can't remember which you need

Ditto stainless bleed-nipples in all sizes.

Do you need more help than this?

I was caught out when I first got my Sport as I did not realise there were ball bearings under the bleed nipples.These were corroded.I have stainless bleed nipples now but have never looked at the pistons.Yet!

If the calipers are the same as the earlier 31/2 the part number according to my book is 43 09 21. Mdina have the kits, but I'd check first as it says 41mm on the description.
