These drums are getting near impossible to find in even fair condition. I have had nothing but problems with them since my wife has had her car. I finally went to 5 bolt last month and it is fantastic as it finally brakes normally and most of all, safely. Best of all, you can find parts for them now. I went through 4 sets of 4 bolt drums over the last year only to find just one drum that could still be turned. The last one set overheated on the rear right and caused lockup and heavy smoke and heat on the freeway. I could not even touch the rubber on the tire as it was so hot. Thankful it did not catch fire. Get rid of them.
