In error I loosened the wrong bolts on an MGB front caliper aiming to take it off the car, but I have managed to loosen the two halves with a leak of fluid. I know this is something I should not have done but what can I do about it? How are the two parts of calipers reassembled after refurbs to prevent leaks: is a sealing goo like Locktite used or are the bolts just screwed up and what torque setting is used?
I'm not an MGB expert so I may be wrong, but the usual caliper uses no sealing compound, a square section O ring that's hard to find and special torque-to-yield bolts that must only be used once, and must be re-assembled with a torque wrench.
No idea if this works for MGBs, but if you need rebuild parts for a Herald caliper then you can get them off the shelf from a Land Rover dealer (or at a great deal of time and trouble from a Triumph specialist). Classic RangeRover calipers use the same parts.
It's an easy re-assembly, but you do need to replace that O ring and the bolts.
And I've split countless calipers and have never renewed the O-ring or bolts. I've never encountered any problems and would be very surprised if I did.

Surprised ? You'd be fecking terrified!
Some time ago there was a thread on splitting these calipers (to remove stuck pistons, AFAIR) and I remember being severely flamed for having the temerity to even suggest that there were any "user serviceable parts inside". Putting brake components back together with recycled rubber seals that are probably older than the driver doesn't strike me as the smartest idea.
It's always worked for me from 40yr old Cortina calipers through to 2yr old motorbike calipers.
