Re worked the parking brake on my 05 Liberty. Actuator levers were rusted solid on both sides. Took me a while to get them out, cleaned and lubed up, but they are working now. Pain in the butt and not cheap. $25 for the dinky little shoes, $26 for the hardware kit. I'm pretty confident that they will rust solid again next winter. For those of you unfamiliar with this setup, the rear brakes are a drum rotor setup with the drum part being the parking brake.
They have never been fantastic. One of these days I'm going to install a hydraulic line lock on the rear brake line and just get rid of the brake shoes.
