My 1990 Ranger XLT has rear drums and they would lockup the right rear drum on the first stop everyday unless you were super easy on the pedal. My wife never learned this and refused to drive it. I replaced shoes and drums to no avail. Last year I replaced the shoes again even though they were not worn but I also replaced all the springs. It just turned 100K miles on its odometer from new. I found that Ford had installed the wrong color spring on the rear shoe on that side. I put the new springs on and it has never locked that wheel again. Only took 32 years to figure it out.
