Stripped caliper pin removal.

[SMSW]

That's what I thought - so I reckon I should have reduced the torque to about 14Nm Don't quote or use that figure - it is an illustration and is not reliable.

I make a practice of slobbering anti-seize on just about every fastener on my cars and bikes, unless they call for a thread locker (well, I'm a lot neater than 'slobbering' indicates). And I've never had any bolts loosen from vibration - except way back in the vibe full ages - notably on my '69 Triumph (but that was pre anti- seize too). Really don't like frozen nuts or bolts though by now I'm probably as good as everyone else removing them (not counting pro mechanics).

The thought here was that torquing to the specified 18Nm when grease was applied might have made them way too tight and be the cause of the hex socket stripping. 'twas just a thought. I'm wondering if (say) 14Nm with greased thread would offer the required resistance to loosening over time.

Not that I'm volunteering to experiment - Its rather crucial that these things stay in place. How would the results be fed back anyway - "If you don't here from me, then the experiment didn't work !"

Generally, applying lubricant where torque specifications denote or infer dry installation means the fastener gets possibly overtorqued, and possibly stretched. The torque calculated takes into account the friction percentage. As such, you have an excellent chance of being correct, provided the threaded section was lubed when it wasn't supposed to.

Why do you remove the brake pad pin to change the tire? No need for that.

I find it easier to remove (and especially reinstall) the caliper when pads are removed. It literally takes 30 seconds to remove the pads, and it allows me to inspect the pads as well as lubricate both pads and pin...well worth the extra 30 seconds IMO, not even considering the time saved when installing the caliper...

I finally snagged a beautiful rear caliper with (with pads!) off of a wrecked '04 from eBay for 30 bucks off of eBay. The icing was the seller was 40 miles away. Installed on the bike and all is good. I now plan to grind off the pin to get some grip for and have it removed from the old caliper. From now on I am always using mild impact techniques to loosen fasteners first before applying raw torque.
