Put some new discs on before Oulton Park 2.5weeks ago and this is them already



The discs are proper scored, on both sides of the disc, both sides of the car. Pads are scored too (pads weren't new though).

Any ideas what could cause this? It hasn't been making any odd noises, binding noises etc.

Don't see the point of putting new discs on if you're not going to do the pads while you're at it

Souldnt really do just discs, as you wont get 100% face to face covered on the brake force.

So you have just been braking on the high spots of the pads, causing the grooves on the new discs.
