Problems after new rear discs fitted.

[Kerdual]

Spent the weekend fitting new rear Pagid discs and pads to my 2004 x3 3 litre auto. On one side the originals had been badly scored by a stone or piece of grit. The fittement was quite easy although I had not come across the back soft lining on the disc pads before and had to look check online to see you don't copper grease the rear as the pad are already prepared with this lining. Cleaned the discs and made sure no contaminant on the pads and put it all back together.
Tried to adjust the handbrake, but there was no way I could see the adjuster through one of the wheel nut holes once assembled? Fortunately the handbrake appears ok.
Everything was fine for two days, nice shiny discs and pads have seated well, but today when braking after the discs are warm I get a rotating sound from the rear echoing through the car. Is it a film on the new disc pads?
Any ideas anyone,?

Did you clean the grease coating from the discs?

Also it could be the lining has come away from one of the handbrake shoes

Yes, cleaned the grease off the disc both sides. Possible handbrake shoe, although handbrake working well. I am right that you adjust the handbrake through one wheel nut hole, seems impossible but everything I. Read seems to suggest that?
As an aside I have been advised to go through this procedure when parking , go into neutral apply handbrake, release foot pedal so car rests on handbrake. Reapply foot brake and into park, switch off. I am told this prevents the car resting on the parking gear. Anyone know if this sounds right with an auto box.

Sounds right.  My handbook says to put in Park, switch off, release the foot rake and the apply the handbrake.  On a slope put the handbrake on before releasing the footbrake.  It is to keep the pressure off the park pawl in the gearbox and old the handbrake - it's what it is there for after all.
