Hi I have a 1963 Mini Countryman. It has a problem with the front brakes in that the wheel cylinders (single leading edge type) have seized and need replacing. I'm having real difficulty finding suitable replacements. I found a pair on eBay, produced by Lucas which are supposed to be compatible with "Austin/Morris Mini" and indeed they seem to be in every way apart from the position of the dowel in the back of the cylinder, which locks it into the back plate.
A possible and obvious fix would be to drill a new hole into the backplates R and L so that the dowels in the new cylinders fit - but my question is would this be appropriate? Has anyone else done this before?
Clearly it is essential that the cylinders are locked into position, as otherwise they run the risk of twisting, which could run the risk of brake failure - something I'm certainly not willing to contemplate.
Your thoughts and advice would be gratefully received.
