i replaced my front brake pads and rotors about 6 months ago. As i was driving last week i heard a squealing coming from my front left brakes when i apply my brake pedal going slow. i pulled the front wheels and the pads still have more then 1/2 the thickness left and the rotors are not warped. What would cause the front left pads to squeal does anyone know? When i had the wheel off i sprayed brake parts cleaner all over the rotor and pads just incase something was caught up in there. After i put the wheels back on it stopped squealing for a day or two then the squealing came back. I'm stumped, does anyone know what would cause this. if i apply the brake pedal hard it doesn't squeal it only does it when i apply light pressure to the brakes. i hope someone has a simple answer to this. thanks in advance

Sounds like cheap pads or no anti-squeak goop on the calipers.

 

The pads were from ford and there's pleanty of anti squeak on the back of the pads. The pads are basically glued to the calipers.

 

Are your slide pins sticking?
