Focus ST rotors

[fiestaz]

Hi all,

Last year I did a track day and heat damaged the brake pads and rotors on my focus st. We fixed it (probably the cheap way) by machining the discs (believed to be factory ones) and putting in bendix pads (just a normal regular use pad I think). Anyway after a long trip I’ve just completed, lots of mountain roads, a lot of brake use, the discs have become warped, worse when hot. Small vibration when in the pedal, gradually getting much worse with a lot of use. My uneducated guess is it’s because of the much harder pad on the soft factory disc.

Can I get a suggestion on whether to replace the just discs and keep the relatively new pad, or whether to go all new. This is for the front only. And also what to replace with.

Sorry for the long post. But thank you.
