Torque values for brake job

[yumling]

Planning on doing a brake job which includes new rotors. Greg's DIY is excellent.

However, does anyone know the torque values for the caliper bolts, etc. Also, what is the torque for the lug nuts for the wheels.

Lugs are 80 ft-lb but I don't know about the rest.

Caliper Bolts:

Models 210 .00/01/02/03/04/05/070/072/08 except 210.072 with Code 957 (E50 AMG): 50 Nm

Models 210.20/21/22/23/24/26/27/270/272/28/60/61/663: 115 Nm

Bolt for front brake pad wear sensor connector: 30 Nm

Brake Hoses: 18 Nm

Locking Bolt on Rotor: 10 Nm

Lug Bolts: 110Nm (I beleive)

after 500 miles,be sure to follow bedding in procedure from brake pad supplier ,that will insure no warping and longer life.

Get buy the kroil before you start the job

Thanks folks. I use PB Blaster instead of Kroil.

That is correct. 80 ft-lb = 110Nm.

This is very helpful--does anyone know the torque value for the caliper carrier? The thing that holds the pads and that the caliper bolts to?

TIA,

Chris

Correct me if I'm wrong:

If I don't replace the rotor, the caliper bracket does not need to be removed, Those two bolts are called "caliper bracket bolts".

If I'm only replacing the pad, I need to remove the caliper mounting bolt (allen head), what's the torque for those two bolts?

When you used the term "Caliper Bolts", are you referring to the caliper mounting bolts? or the caliper bracket bolts?

Thanks for the help.

If you have floating style calipers, the bolts which hold the floating middle portion are called caliper guide bolts since the central portion can move along them as the pads wear. If you are just doing pads, you only need to remove those. If you are replacing the rotors, you will need to remove the entire caliper by removing the caliper mounting bolts.

BTW, the 110Nm lug bolt torque is for the short style lug bolts. If you have the longer style (you can see the bolt heads when the wheel is mounted) the correct torque is 150Nm.

The bleed valve torque is 7Nm. But unless you have a small torque wrench of say 0-25Nm I would just tighten firmly by hand since you can easily overtorque with a torque wrench is too big.

Thanks for all the above info, but I still would like to know the torque values for the caliper bracket bolts. Does anyone know?
