Brake disc replacement - torque settings?

Finally getting around to fitting the new front discs.

I had a search but there are so many results fitting my terms, so does someone have a sheet with the torque settings for the wheels, disks and calipers?

Also - grease the pad pins with red rubber grease, or not? - I've heard various opinions. Perhaps best to see what conditin they're in when they come out.

Thanks

Wheel bolts ~ 130Nm

Disk retaining screw ~ nothing much - it's just to stop the disc falling off or spinning while you put the caliper & wheel on so just nip it up

Caliper pins ~ 30Nm. A thin smear of grease if you like. I must admit I've never got any so a spray of WD40 if it's to hand. More important to clean them up
 
E46 M3 specs, but close enough.

Caliper slider pins are cheap to buy so I always replace them when I'm in there, and I don't use grease. I do use copper grease on the disc retaining screws and the caliper pin threads. If these seize, a simple job becomes a right pain.

Well, all done.

It all came apart nice and easily, the pins (blimey they're a bit more substantial than the ones on my bikes) were in good nick, the wear sensor was a bit of a faff to replace but seemed to go in OK.

But best of all I didn't even get my hands dirty.

"Why not?" you ask, well.....

As I was rolling it out to get started, a neighbour had a mobile mechnic working on their car. "Ooh, nice" he said as he was just finishing up. "Yup, I'm just about to have a go at the discs and pads, don't fancy lending a hand" I joked.
He checked his watch, said "my next job isn't until after lunch", and so 75 min, 1 cup of tea and £50 later all was done, and he even let me watch.

Copper grease on the pin threads, no grease on the pins.
