The thread in the adjuster barrel of my front brake caliper is shot so I'm looking to replace the whole thing - and probably the back one too as I don't think you can buy single calipers (can you?). My usual practice when replacing bits is to get slightly better quality gear than whatever it is I'm replacing - which in this case is Campag Centaur. So I'd be looking at Athena or Chorus if I followed this rule. I'm curiously drawn to Chorus but it would mean spending more than twice as much (£100+ instead of £40-50). So the question is: is Chorus worth the extra? Or even Athena? I've been quite happy with the Centaur brakes on the whole - could do with more stopping power and better performance in the wet but then couldn't we all?
