warning lights/messages came up on dash board and the hand brake would no longer work, has red flashing light on handle .Eventually he got the release handle to work (pulling bloody hard) and the brakes released,but dont work! he has tried the suggested re-set procedure on this site to no avail,there is obviously not a problem with the mechanism as it has work flawlessly in the 3 years we have owned the car,what to do next ,any help would be appreciated..thanks...this seems a crazy thing to happen just by
changing pads !!!!!
