CALLIPER UNION FITTIN

[Gromitdog]

Could anyone tell me what size thread is for the union that fits into the caliper or can anyone tell me where I can sorce one as the company on ebay who supplied me my SS brake hose have supplied the wrong one as I decided to do away with the copper pipe part and just extend the lower hose it wouldn't tighten up just hope i not damaged the thread in the calliper ( old fitting seem to tighten up ok so 🤞)
Nothing seems to be going right here on Muttley right now can't find the old exhaust gaskets either 😒😒

Hi Gromitdog, the thread pitch is 1,25, same as  the caliper bolt and banjo bolts (same size and thread). hope this helps
