Hi Andy - any garage that changes the cylinders and not the shoes ain't competent in my opinion - considering they only cost around £15. Generally adjustment doesn't affect imbalance in the Northern Ireland test. As already said if the original cylinders were leaking then there is the distinct possibility either the shoes or drums have become contaminated. If that is the case the shoes will need replaced and the drums need to be cleaned using heat as the metal absorbs the brake fluid and will re-emerge when hot. As I live in Northern Ireland I have seen this type of MOT failure on many occasions.
Currently in madnoel10's garage:
