Bill its probably a combination of things..the return springs may be week and the shoes a little out of adjustment...the shoes can get grabby when the springs are not holding them tight and they will bind up...how are your fingers??? bet that wheel was really moving when it took off on ya...when I worked at the dealer in the used cars... almost all the cars ended up with new brakes before we sold them on the lot...man I did a lot of jobs and sucked more brake dust than I should have back then...where the heck was osha...hope to make it to 75....
