Squeeky Front Brake - 939

Redress the front discs, pull the pads (replace if necessary), apply a thin layer of caliper grease to the back of the pads. Should be smooth and quiet.
 
Search the brake threads. Most likely sticky bobbins on the floating discs. Put a thin coat of grease on the bobbin race and be sure they spin freely. I have to do mine every couple months or they start chattering and making noise.

Pads are not the problem.
 
Common practice, has been done for as long as disc brakes have existed. All it does it prevent the pads from resonating, which causes the squeek. No way for it to migrate to pad surface.

My concern with grease on the pads and for that matter the pins, is that it holds dirt and grit. I know they make grease specifically for this purpose, but I've stopped using it.
