Hi, I have a 2006 Peugeot expert 2.0 HDI and have an unusual fault, the front drivers side brake is binding, I have had the caliper, brake hose and master cylinder all replaced and still the problem persists, strange thing is I can drive for an hour and no issue then all of a sudden it will return. needless to say it has been off the road for a week now until I can get this issue resolved , any help would be greatly appreciated.
