Copper grease on threads

[BiggestNizzy]

Worse case apply a little heat to the bolt and it will melt it allowing it to be removed easily.

It doesn't take much to shift it anyway. it's more for resisting vibration.

Just get low/medium-stength stuff, sounds daft but for stuff that will eventually come apart its best. As above, when compared to the alternative of dry assemble and corrosion, threadlock means it's a calibrated break-free-stiffness not infinate-welded-with-rust-stiffness followed by snapped bolt...

FWIW: I used wavy washers and nylocks/stiff-nuts on the Porker (That's what Porshe use) and copperslip everything.

It's not hard to break....it just stops vibration shaking it free. Just have some wheat-a-bix beforehand!

Okay . . . so copper grease and threadlock serve the same purpose in terms of preventing corrosion from sealing a bolt in place and being impossible to remove, it's just that copper grease makes it really easy to get off again wherease threadlock ensures vibration doesn't loosen the bolt and keeps it locked in place.

Think I understand now

Important also to differentiate between threadlock and studlock. Don't studlock a bolt in if you ever want to get it out...

Copper Grease is used to prevent things from siezing.

Threadlock is to prevent things from coming undone.

Just to clarify - copperslip stops stationary or very, very slow moving things (Like brake caliper slides) moving things need proper oil or grease.

I say this as I have found a couple of Porker wheel bearings packed with copperslip...

I thought coppaslip was used so we can easily tell when Dave's installed the pads the wrong way round again

Have heard/read about this a few times, do you mean wrong way as in backing plate against the disc??

Springs to mind.....

I would suggest that if you need a "picture heavy" guide to swapping out brake pads then perhaps you shouldn't be doing such a safety critical job on the car on your own.

Hence

No guide is ever fully idiot proof.

Thing is Dave had been shown how to do the brakes a few times prior and had even done them on another SE'rs car (under supervision) prior to this.

I did ask when he turned up at my door complaining of a bizarre noise and when I asked because I saw the coppaslip on the disc was told in no uncertain terms that the pads were installed the right way.

Of course I'm not one to gloat :
