W212 E350 CDI RWD - Front brake caliper torque settings?
Hi,
I'm seeing some conflicting info online, some people say to torque the caliper bracket to 180nm at the front, some people say 115nm.
The caliper slider bolts are 25nm? The Brake disc Torx bolt that secures disc to hub - 10nm?
Could somebody let me know the correct figures, please?
This is a single piston brake caliper from a 2010 E350 Sport CDI, rear wheel drive.
Thanks!

115 Nm, no degree yada yada.
4 piston or single piston is the same, the bolts are the same and so are the female thread at the knuckle.
So you solved ur sticking brake issue and the wobbling ? What was the cause ?

Thanks so much!
Yes, I did thank you - I believe stuck caliper bolt slide pins meant that it was only pushing the disc on one side, allowing a gap to be created between the hub and disc and rust to form on the hub/back of rotor.
Once the hub and rotor were cleaned, it spins true on the hub (once bolted down properly, not with just little Torx screw) :-)
I ordered a new caliper slide pin kit for both sides! I'll do the other side too just for good measure :-)
