I recently got my brake-pads replaced at the LBS - Since I live on top of a hill, I asked the bike mechanic to set the brake-pads with minimal clearance from the rim. The rear wheel settings are perfect but the front wheel has a slight rub. The mechanic said that the brake-pad will level off in a week or so which hasn't happened yet. Should I go back to the LBS or let the brake-pads wear off? Does it significantly impact the rim? Btw the front wheel is true.
