Caliper mounting bolts - Threadlock or Coppaslip?
 

First of all let me thank everyone who has ever contributed anything useful to a thread on brakes - caliper servicing, seized piston removal, bleeding, anything - I read them all and needed to! Also about one PM away from going on Northy's banned list, so a special mention there :salut:

Anyway, just two short weeks after I started on my binding front brakes (I made every mistake ever heard of and invented a couple of new ones) I am ready to remount the caliper and sign off, when I run headlong into this wobbler...

Haynes - Apply a suitable non-permanent thread locking compound to the caliper bolts
Bike magazine - Apply copper grease to the threads of the caliper bolts

You're having a laugh! Which is it peeps? Thanks for your vote.

And think yourself lucky you're not coming on the Ecosse rideout this Sunday or you'd have to hear the whole sorry tale :smile:

for a road bike I would thread lock them, for a racer I would copper grease and lock wire.

As of 5 o'clock it's 4-2 for thread lock. Good enough for me!

(Unless the 2 for coppaslip were Spannerman and Sid Squid of course...)

Thread lok:D

Re: Caliper mouting bolts - Threadlock or Coppaslip?
 

Threadlock unless there's an alternative locking method such as tab washers, lockwire etc.

Non peminent thread lock---and----THE CORRECT TORQUE.
Remember these are screwing into alloy casings and it is so easy to strip them by overtightening

Re: Caliper mouting bolts - Threadlock or Coppaslip?
 

They coppaslip them at every reputable bike dealers I know, and I do the same. Just make sure they're torqued correctly.

I hardly threadlock anything, but then parts tend not to stay on the bike long enough to rattle loose ;)

Re: Caliper mouting bolts - Threadlock or Coppaslip?
 

Copperslip.

I use titanium bolts and these came supplied with the CS.

Never had a problem with them coming loose. *Touches head*

Re: Caliper mouting bolts - Threadlock or Coppaslip?
 

Nothing.

Copper grease.

Re: Caliper mouting bolts - Threadlock or Coppaslip?
 

Clymer never mentioned threadlock or copper grease for the DRZ mounting bolts...

Re: Caliper mouting bolts - Threadlock or Coppaslip?
 

It depends on the design of the bolt. If the head of the bolt was smooth on top or slightly domed then I would use thread lock. If the head of the bolt was hollowed out then I would not as the shoulder of the head of the bolt is designed to distort and grip the surface of the metal below tighter than a standard bolt.

Copper slip, pretty much everywhere, and do them up either tight, or in critical areas 10% less than given settings.

Never had anything vibrate loose yet, and when I come to loosen things they seem to go "ping" then wind out smooth.
