2009 S550 Brake caliper Torque
HI guys, Im changing all 4 rotors and pads. Can someone please tell me what are the correct torque specs for
1) Brake Caliper Bolts for both Front and Rear,
2) Rotor Alignment Screw, and
3) Wheel Lugnuts.
Secondly do i have to replace the caliper bolts or can i reuse them ?
Thanks in advance

110nm for the caliper bolts, 150nm for the the lug nuts. 8nm for the set screw. Going from memory, actual values may vary by 1 to 5 nm for each.

Thank you for you help.
But I'm confused. Is it 110 nm or 110 ft-lb ? If its 110nm then it will be 81.13 ft-lb. But the video posted by 39039 (Junior Member) about replacing Front pads and rotors indicates that the torque is 133 ft-lb for front calipers and 110 ft-lb for lug nuts.
What about the rear calipers? .....Please help.
