Asked by Jun 18, 2013 at 01:12 AM about the 2012 Ford F-350 Super Duty King Ranch Crew Cab LB DRW 4WD

Question type: Maintenance & Repair

2012 ford f350 dually 6.7 Dsl. The has run flawlessly for 1200 miles. Last week cruising
down the highway. The tuck started to loose speed. I accelerated to compensate but Ge
brakes forced me to pull off the road. All four calipers stoking hot. After sitting a hour
waiting for a tow truck the brakes went back to normal. Drove it to the dealer for
diagnoses and repair. They couldn't find a problem. Picked up the truck and drove 3
miles and problem reoccurred. Help!

Make the dealer look again, and/or make the mechanic drive it until it happens. Or try another dealer. Your brakes are dragging. There is a 'reed valve' or 'flapper valve" that keeps the calipers from sticking, and when it happens on all four as you describe the problem is likely in the master cylinder

the master clylender has an adjustment from the booster if that adjustment is to tight it wont allow fluid to return to the master clyender resivour therefor its trapped between the caliper and master the dragging break createts heat which intern buildspressure in the line applying the break until it pulls the stearing or just strait stops the veihicle only bwhen the breaks are cooled down will it move or rod behind master cly has a little free play allowing fluid to get by orffice to the resivour
