Tchirp sound on my wheels on Audi A4
It sound like you have touch all the base, so your going to need to check the dust shield on the back side of the rotor. Make sure that it has not gotten bent forward towards the rotor and wheel rim area of travel. It's a common thing to happen as the brakes heat up the dust shied warps slightly and if there is not enough gap between the dust shield and rotor, and rim will make the chirping noise you hear. You may not even have top remove the wheel to fix this, just turn your wheel all the way to one side so you can get to the back side of the brake assembly and push the dust shield away from the rotor/wheel area. Good luck and hope this helps. keep me posted. be glad to help you get rid of that Gremlin.
