Recently after having 17" Enkei's put on I noticed that with light pressure applied to the brake pedal I will get a constant squeal. After released brakes operate as normal. Pads are about 3yrs old and in good shape. Should I be concerned ?
I previously had OZ wheels on with same tires/brakes and no squeal.

Thanks for your help.

Had similar issue but mine started a squeaking noise when letting off the brake pedal. It was like something dragging on thin tin.
Took it to a good power wash place and sprayed the heck out of the wheels. Since I did that the noise is gone so I assume it was something stuck in the pads or on the rotor and backing plate.
I also suspected that my coilovers had something to do with it since a week earlier I installed them.
Must have been a coincidence.

 

Brake noise is usually due to vibration. Maybe coincidence, but check your pads and rotor for wear. If you swap out the pads get the rotors turned too. Also install the steal shims and line the bads w/ silicone (sold as a gel to reduce brake noise). These are inteded to absorb vibration.

At a minimum, check all lower suspension, brake, and wheel hardware.
