1993 Ford E-350 Q&A
1993 Ford E-350 Question: Why are my front brakes holding?
Open bleeder to see if pressure still present without brake applied, if so then possible booster return spring is weak or broke inside the booster. Next unhook vacuum hose at booster and see if brakes release. Does the brake pedal move freely when tested by hand? Brake lights turning off when pedal released? Was this work done to correct THIS problem to start with? - pushrod
