Parking brake woes....

My park brake was not releasing properly so I dropped the driveshaft and pulled the drum (dead blow and some back and forth pressure got it to let go). The cable adjustment seems correct as does the shoe adjustment. Only thing I found which I suspect is the problem is the shoe expander assembly slides back and forth in the backing plate. (Not the individual pistons they move freely as they should but the entire housing which looks to semi permanently attached) I suspect that is supposed to be tight and it slid off to one side and jammed but not 100%. Can anybody confirm or deny this theory?

The assembly is meant to be able to move. It allows the shoes to centralize on the drum. Make sure everything is properly lubed and both springs are installed properly.

Cable is moving freely as are the expanders. No binding, last adjusted and greased late last summer. Plan to grease it again before reassembly. ------ Follow up post added July 13th, 2016 08:06 PM ------ One thing to note. The shoe adjuster has always been at the minimum setting to keep the shoes from dragging.

Are the shoes installed properly and the expanded assembled the right way. It is easy to do wrong.

Mine was always fouling after offroad jaunts. I ended up replacing it with a xbrake

Thanks! This video pertains mostly to the cable actuated brake and I have the rod actuated. I dont remember the shoes being different for leading vs trailing but will double check tomorrow.

The shoes have a leading and trailing end and an adjuster and expander end. There is only one right way to install and you need to get it correct. Note the two shoes are different. The picture in the workshop manual shows the details. You also need to make sure the expander is assembled with the ramps facing the right way and the rollers aligned. It is easy to get wrong and it will still work but not well.

Turns out I did have the shoes reversed leading for trailing. Surprised this is the first time I Have had trouble considering I replaced the shoes over a year ago! Seems to be working well for know however.
Thanks
