Front brake

[Graeme 1978]

Hi still having a problem with my front driver side brake WELL a think it's the brake that's what a need help or advise with.
So the problem is when a steer right am getting a noise which sounds like the brake pads are rubbing on the disc and NO noise when a steer left.
This is what I have replaced up to today.
Front discs twice, front pads twice, front wheel bearing and today a new brake caliper.
When the caliper and pads are off and turn the disc by hand there is a slight wobble if that makes sense all this noise started after a fitted the first set of discs.
So has anyone experienced this sort of problem before.
The passenger side is perfect.
Can the hub go bad or is it just the bearing that fails.
W212 2.1 auto deisel on a 12 plate.
Thanks for any help and or advice

There shouldn't be a noticeable wobble when rotating the disc by hand (a small amount of bearing play is allowed - no play at all will cause bearing failure) but you shouldn't be able to see it by eye.
Did you clean the hub and ensure that there was no label on mounting face of the disc before fitting?
A badly fitted bearings could put the hub out of alignment.
I've had a bad bearing failure cause issues with the stub axle - did the new bearing present a snug fit on the axle?
I've had a loose bearing cause the disc to rub against the brake backing plate when manoeuvring into a parking space (as MB wheels lean a lot when turning hard).

Check your hub with a run out tool to see if it's not warped

Ye bearing fitted nice and snug a need to check it with a run out tool but a don't no whats a pass and a fail on the run out.
No labels were present when fitted discs if there is to much run out can a just nip it up or do a need another bearing thamks
