I did a quick search but didn't find this.

I have new Balo rotors for my W126. I am about to start the job however before I disassemble everything I noted that none of the holes in the new front rotors are threaded?

I believe the rotor is held to the hub by 5 bolts from the inside - however I would expect that the rotors need to be threaded? Part numbers I have (both front and rear and I may have mixed up the boxes so I will post both

Balo 02078 - 126 423 0012 (115 423 0412)
Balo 02041 - 126 421 0012 (126 420 0005)

126's up to a certain year year had bolted on rotors. After a certain year, they were like most modern Benzes, where only a small locating screw holds it in place for assembly.

If I remember correctly, on the earlier models, the hub is threaded, not the rotors.

All 126's have the rotors bolted to the hub.

No threads on the rotors It'll all make sense once you pull things apart.

Doh - yea just pulled all the wheels (looked closely at the manual as well) - rotors go on from the back - threads are in the hub.

Now the worse problem - place that put new tires on cross threded 3 bolts in the rear

I'll see if I can get them to cover the repair
