Fil M Posted June 3, 2012 Share Posted June 3, 2012 Hello All, I have got the tub of copper ease and brake cleaner and am going to undo the two bolts holding the rear Sierra style brake caliper. Once opened I am going to give it a clean and lube and reassemble to stop it 'singing'. If the linings are in good condition I will simply reassamble without need of rewinding etc. Can anyone tell me to what torque I need to synch up the two retaining (slider) bolts when I have finished please. MOT is due so I am giving her the once over with the tooth comb Cheers Fil Link to comment Share on other sites More sharing options...
6speedmanual Posted June 3, 2012 Share Posted June 3, 2012 Done up firmly with a normal 6" long combination spanner is sufficient. However they should have a thread locking compound applied before threading in. New bolts supplied with pads have locking compound patch.

DJ. Posted June 3, 2012 Share Posted June 3, 2012 I can't remember where I found the correct figure, I think it was the Haynes Sierra manual, but according to my records I used 20Nm for those bolts and they're still there Duncan Link to comment Share on other sites More sharing options...

Stationary M25 Traveller Posted June 4, 2012 Share Posted June 4, 2012 They sound like caliper mounting bolts, not the sliding bolts ? Link to comment Share on other sites More sharing options...
rj Posted June 4, 2012 Share Posted June 4, 2012 But that's brake calliper to DeDion ear. Not the sliding bolts. 20Nm sounds about right though I never use a torque wrench for those. Link to comment Share on other sites More sharing options...
Fil M Posted June 5, 2012 Author Share Posted June 5, 2012 Thanks Everyone, I have taken them apart and the bolts didnt need a lot of grunt to get them moving. They had a coat of blue locktite on them and I have synched them up firmly for now with the original blue compound still on the threads. I shall get a short torque wrench to check them because mine is a bit big for the space available. I shall put some fresh blue loctite on them too. Brakes are now squeek free.

elie boone Posted June 5, 2012 Share Posted June 5, 2012 A 1/4 turn before they snap 😬 i never used a torque wrench on those Link to comment Share on other sites More sharing options...
Fil M Posted June 5, 2012 Author Share Posted June 5, 2012 Thanks Elie .... will the original blue loctite on the threads still serve the purpose? or do I need to refreswh it? Fil Link to comment Share on other sites More sharing options...
elie boone Posted June 5, 2012 Share Posted June 5, 2012 I can't see that there is a lot of load on the bolt but if you buy new pads it comes with new bolts. i just do them tight up and never had one that has worked loose, with or without new loctite.
