Did you fit different sized tyres to the rears than are on the fronts?

 

Even a small difference in size will confuse the ABS ECU.

[DennisVrs]

yes it is exactly the same sadly...

Which bearing was changed?

[sepulchrave]

Then the wheel bearing is not correctly fitted.

Resor right was fitted 3 weeks Ago tho. Tourced right and so on :(

Don't think it's possible to mis-fit the rears. Fronts are a different matter.

Thought so too there is a ton of rust and brakedust on the left one.

Can that cause the problem?
