To be clear, after weekend work car now has 2 new discs and 4 new pads (also full new oil, new oil filter , new air filter and new wing mirror).
In a week I'll take out new pads for an inspection and see if they are wearing in evenly and recheck caliper function or if anything is sticking. ( I phrased that badly before, sounded like I was leaving old pads in for a week)
