i have a 93 wrx with grooved discs on the front and standard braakes on the rear. when braking from 90+ it makes a strange vibration noise. the pads have loads of wear left on them but i noticed that the brake discs have gone blue in places. i expect this is from thee heat. this is obviosly very worrying what do you all think

I'm guessing that the noise is more of a dropne, that's normal for grooved discs, andf the blue is heat, and also isn't a problem, although it can lead to bigger things, just keep an eye on them!

cheers ron. do you think i should replace the discs and pads though mate

RON

Not if there's plenty of life left in them, and so long as they work ok, the droning is normal, and the blue is just heat, if they start to crack, then replace them!!
