ok the disks on my 01 legacy are the drilled and grooved ones,i was driving home today and this awfull screehcing sound coming from the front right wheel sounds like a pebble got stuck in the pads,,took off caliper and check pads and cleaned everything, ,didnt find anything,put copper grease and all.back down the road and the screeching comes back but it only starts making noise when they get hot under heavy braking,when there hot they will start makin noise but when I brake it goes away?? my mechanic now thinks that my disc is warped.would warped discs make that awfull scratching sound??if so would it be best to fit standard discs back on instead of new drilled ones as i only put cheap pads in anyway.???which of these would be best?is the 294mm the correct size?
