a friend of mine has a 93 Ford Escort Estate and every now and again the back brakes bind on and eventually free off again whilst driving.
He has replaced all the back brake shoes and free'd off the self adjusters does anyone have any idea what could be causing this, he says it mainly occurs after harder than usual braking?
I have noticed under the bonnet on the passenger side inner wing there are two canisters one in line with the rear brake pipe and another in line with the front brake pipe. Whate are these canisters and what do they do? Could they be the cause of the problem?
I hope someone can assist it is driving him barmy.
