i m also having issues with my brakes since last one week or so. took the car for the 1000 kilometers inspection. they lifted the car and in addition to changing the engine oil and filter, i had requested them to rotate the tyres, front to the back and back to the front as mine are directional (advan db). when they opened the wheels, the cleaned the pads in the front and rear and also cleaned the drum in the rear. after getting the tyres rotated and leaving the showroom, since then my car produces a ggghhhooooooooonnn kind of sound every time u apply the brake even from say 65-70 km/hr to slow down, and the sound remains there till the time brake pedal is pressed. the moment u release it, the sound vanishes...the sound is just like the sound produced from the tyres of an Army jeep if u guys have heard it, i mean as the speeed descreaases, the sound also reduces till the time brake is applied....like a heavy humming voice.
what can b the reason ? the rotation of tyres after this less a reading, that too such top quality tyres can not be the reason , can it ? or is it again to do something with the wrong fitment of the brake pads
