The non vw dealer i purchased my multivan from 5 months ago replaced the tyres, brake pads and rotors as part of the deal. The tyres are Trazano brand which i've never heard of, and are very noisy which i can live with until they're replaced, however there seems to be quite a bit of noise from the front brakes. As i apply the brakes and slow right down there is a grinding sort of sound which is similar to the sound worn pads/rotors make, however the brakes are almost new.

i did run in the pads when i picked up the van, so not sure what's going on. I haven't had a chance to take the wheels off for a closer inspection yet, however when i get around to it, is there anything in particular i should be looking for?

Is it worthwhile going through the run in procedure again?
