My rear 105 caliper must leak somewhere, me and local mechanic tried everything and it still howls and loses power. Would you swap for a new 105 (£45) or something like a Hope (£85) or anything else?

Go new 12s generation 105 or above.
Or my most reliable caliper so far has been tiagra or grx 400 (same thing afaik). Don't burst pistons at anywhere near the rate of older calipers and don't have that insane silver screwdriver pin of death that shimano decided was sensible to fit
