Check for a frozen or sticking parking-brake cable, especially after frequent use on a hill, and compare rear-wheel drag by jacking each side and trying to spin the wheel. Also check whether the opposite wheel cylinder is balancing brake pressure. Because brakes are a safety item, have a certified technician diagnose and repair them if you are not already familiar with the work.
The owner of a 1993 Ford Explorer says the rear driver-side tire locks and drags in drive but still moves in reverse. The expert suggests a frozen parking-brake cable or an unbalanced wheel cylinder and recommends comparing both rear wheels by jacking and spinning them. The owner has been using the parking brake more often while parking on a hill. The expert says brake work is a safety item and is best left to a certified person if the owner is not already familiar with it.
