I own a 08 Grand Touring with brembo brakes and my front left speaks/squeals as i am braking lightly. Went to a shop to get it checked and was told that my brakes have are at 50% or more life left, but they still continue to squeak as i brake. Any suggestion on what i could do to fix the problem would help a lot. Thank you!

 

Take the pads out and apply some grease to the areas which contact the pistons and the pad guides inside the caliper.

 

Plus, while pads are out, check fore/aft chamfer of pads. If none, re-cut 45 deg chamfer, run some 220 grit sand paper across the faces of both pads and rotors to knock down any glaze, reassemble.

 

OP, did you remedy your problem?
