Creaking Rear Calipers?

[Matt_16v]

Right,
Rear wheel bearing finally done, got rid of that bloody noise

Now the caliper on the nearside rear is creaking? What causes this??

Thanks in advance

Slightly sticking? remove clean and copper grease the sliders perhaps

never use copper grease on brake rubbers as it kills them. only ever use red rubber grease

[Coops]

both my rear brakes creak like ****!
