Brake rotor and pad replacement coming up..need torque specs

I'll be replacing my front and rear brake rotors and pads in addition to my parking brake shoes at the end of the week. Anybody know the torque specs for the rotor securing screws, caliper to mounting frame, and mounting frame to steering knuckle front and rear? I attempted to look them up, only to find the info scattered across multiple sources, so I'm a bit confused. Psyched to be upgrading to this setup though: http://www.ecstuning.com/BMW-E39-540...Kit/ES2586989/

If it's not found by typing /brake or /torque f3 in the bestlinks, then it should be added to these threads when you do find it:
- Torque specifications for all DIYs (1) & one user's example of a complete brake job with all torque figures, specs, measurements, fluids, decisions, tools, tricks, mistakes, suppliers, costs, etc., that it entails (1)

EDIT: Added the picture of the reference above, since these things are ephemeral, over time:

Thanks Bluebee! I've been able to find the torque specs for the front caliper to frame and frame to steering knuckle torque specs as well as the corresponding specs for the rear. I'm really just trying to get these absolutely confirmed, since I've witnessed my brother's brakes fail (luckily only the rear right caliper) after he had DIY'ed his brakes. I'll post what I have so far later.

Front brake specs from the Bentley Manual:
Front brake rotor to hub - 12 ft/lbs - make sure you put anti-seize on threads and just snug it down. The lug bolts hold the rotor on the hub. That little Allen bolt is just a locator but can be a real pain if the Allen fitting gets stripped.

Caliper to frame - 22 ft/lbs (7mm Allen bolt) These are the sliding pin bolts.

Frame to knuckle - 81 ft/lbs

I posted those in January. Rear specs are available from the same source. Vol 1 available online.

Anyone who DIYs or owns an E39 should have a copy so they can know what's going on with their vehicle.

Thanks for the re-post John, forgot that was in my last thread. Should be all set to do the job. Downloading a pdf of the Bentley Manual now.

I made this chart years ago, which was posted in the thread I referenced for the OP...
