Hi! I had an MOT done on my car last week and althogh it passed, i got an advisory note stating that my fronts tyres are nearly illegal (getting 18" rs6 alloys next week) so thats ok. But also it states that my brake pads are worn really thin! I am confused as i have had no warning on my dash to alert me of this (do they all have sensors?). I was just wondering whether to get them changed from garage and probably get ripped off, or do i get disc upgrade and new pads and fit them myself? if so which ones, price etc? The reason im thinking of upgrade is because im thinking of remap down the line. Help Please!
