Torque Wrenches - PITA

[Flukester]

So I thought I'd retighten all my bikes caliper bolts with a shiny new screwfix torque wrench.... you know, do things properly.

Tighten, yep click, Tighten another, roger click, Tighten another, clickety, Tighten another (silence)..Tighten some more (silence) CRACKKKKKKKKKK!!!!

Nice one screwfix you bunch of &*^&, one snapped caliper casting.

Allen bolt in question was pin holding pads in... after speaky with local dealer they agreed, don't use a torque wrench on small bolts, just guess it with hand.

£200 quid down the drain

yeah my fault for trusting a 15 quid job... prolly ok'ish at higher torques, but at 22NM it was a pile'o'*&^%

ahh well.. lesson learned

Aren't you supposed to stop when it clicks then?

yep, there was four bolts, last one didn't click until the casting cracked

maybe it was already hairline fractured... could explain it.
