I put my car through its bi-annual NCT here last week. It failed on two counts battery tray and rear brake imbalance of 42% - it needs to be less than 30%. Can this be fixed with new pads (they are thin and need replacing anyway) or is it new calipers/pistons.?

ps the emissions test gave just 0.15%vol CO2 and 308 HC ppm which was a surprise
