PH2 172 Front Brake Re-Assembly Disaster - Help Please!

[Andyl20]

Hi All,

Had the job over lunch today to start putting my front brakes back together after fitting new discs and pads. Thought it would be a breeze, but hit what I see as a major issue when re-mounting the first caliper carrier to the hub. The lower of the 2 threaded holes for the 18mm bolts has stripped threads whilst tightheing up and I now cant get the bolt to tighten in it. PIc below for refernce to show the offending item:

Question is, what can I do about this? Can I re-tap the thread? If so what would I need to do this? If not are there any other options I could try myself?

Thanks in advance once again for any support or suggestions.

After a bit of internet research i'm thinking a thread tap and new bolt maybe the solution? Only issue is I have no idea what size tap and bolt I would need. Am I on the right track?

Very tough to tap, it's cast iron as far as I know. Any cheap tap will snap off/be useless. Buy a hub, quick look on EBay, available for about £30

As above, less stress to get another hub.

What hubs are you on?. 54mm or 60mm... I have some spare 54mm hubs and based in Birmingham..

Had a quick check and I think 54mm - I've a Ph2 172 so does this sound right?
