Help! We have a 1993 F350 Disel Duelly with low miles. Two years ago the right brake sometimes would not release. The caliper was replace along with new brakes and brake hose. The problem has returned. The brake seems to drag, sometimes getting so hot the brake will smoke. It may release and be just fine for a few days/weeks then it happens again. Any ideas on what causes this? Thanks! Donna

 

Donna ,
Its possible the caliper slide pins or bolts are the problem ? Have you had a look at the rear brakes ? A proportioning problem could also cause problems . Any other details you could provide would be helpful .

Donna,have you had the parking brake cable checked out?They are notorious for rusting up.If Im not mistaken your rear calipers have a cable going to them or its at the rear of the transmission.Hope I could help. Windsor

 

Thanks guys for the info. I forgot to add that this is the front right brake. They truck is getting new front calipers this week. It's sad that it has only 36,000 miles and this is the third set. Both failures were the right front. Thanks Donna

 

sometimes the flexible brake line collapses inward. this allows the hydraulic pressure to go to the caliper but when it tries to go back, the line collapses inward and traps the pressure against the caliper. this causes a brake bind like what you described. if the caliper is found to be free and not sticky, this might be your problem.
