As odd as it sounds, Dale, try applying grease on the back side of the pads
where they contact the caliper puck. Because the pads are pressed against
the rotors when brakes are applied, they want to rotate with wheel... the
caliper housing keeps them from moving---but they still oscillate a little.
If the backside of the pads are dry, the slippage between the puck and the
dry brake pad (as the brakes are applied) is enough to make a squeeling
noise. If everything else is fine, that should fix the problem. Robert
Breaks are making loud squealing noise when applied. Had a tech check it.
Pads are about half used and rotors look OK. No other apparent problems.
Any ideas regarding how one might fix this - short of putting new
pads/rotors on? I have a pair of noise cancelling headphones as an
alternative, but then I can't hear my wife barking at me :-). Hmmm.
