yeah your right. the biggest problem i have is this year model has a drum brake not a caliper/disk assembly. crazy actually. i think we might have figured it out looks like there is a removeable plug in the front of the diffferential you remove and adjust the shoes. i can only hope so.thanks for your help

The parking brake rotor is installed on the output shaft of the transmission,MIGHT be possible to remove it by removing the drive joint but am thinking the whole transmission needs to come out to remove the rotor and assembly....the caliper assembly might be accessible to repalce just the brake pads but not sure on this model truck,have done SELLICK rough terrain forklifts with a similar set up and the caliper was accessible to replace the park brake pads and cable without to much trouble,but that was easy to get underneath also......might have to get it up off the floor COMPLETELY AND SAFELY!!!!!!!!........so you can get underneath it......
