Ok i'm stumped.

I've changed the rear disks and pads, and now I can hear a lovely woosh, woosh, woosh noise like the brakes are touching the disk. turning slightly left or right either makes the noise (nearly) stop or become constant. Pulling the handbrake out slightly makes the noise stop altogther. ?? ideas? Oh yes, pushing the brake pedal just makes it louder. I think it's just the drivers side only doing this, but don't quote me on that. I've pulled them apart and can't see what's wrong. There doesn't seem to be any play in the bearings.

Do you think it might be the parking brake shoes?

As you know the parking brake has nothing to do with pads. The small drum brake for parking has a seperate adjustment for shoe clearance. I think whats happening is engaging the park brake centers the rotor and moves it away from the pads ever so slightly. These older cars do not retract pads away as much as newer cars, I would verify the proper MB disc pad grease has been used on the back of the pads and the surface of the rotor is not excessively scored. If scored, its just a matter of wear- in of the new pads to that rough surface. I've had good luck champhering the edges of new pads to reduce noise.

They're new pads and disks, but I'll have a go at the handbrake shoes again to see if that's it. I think it probably is as the pulling the handbrake stops it. thanks!

Guess what it turned out to be?

the splash guard rubbing on the back edge of the disk.
