uneven pad wear

[Blem]

Hi Matt
Sorry to post as a thread but my pm box is full as is my time & pre Christmas patience.
Recently did a track day at Mallala with over 900 klms on new DS2500 pads & brand new Brembo rotors.
Did a PB by over 1.5secs but discs have warped & pads seem to be wedging.
Ie they are flat side to side but not even top to bottom. There was no sign of uneven wear prior to stomping track day.
Do you think they need a rebuild ?
Am going to throw my spare set of rotors & half used pads on over the festive break.
My car has only 56k on the dial & as I said the pads & rotors had over 900 klms wear.
PS...Thanks for all of your help & outstanding service.
Cheers Todd
