So, i engaged my parking brake today, and when i dissengaged it, it backed up fine, but when i go to drive, the back drivers side wheel is still locked up, ive tried re engaging and dissengaging the PB like 30 times, ran through the transmission and still its locked up! any help!?

Yeah, you will probably need to pull the drum off to inspect the brakes closer. I've never had this issue before, but from the research I've seen that it tends to happen from time to time...

thans for the help guys, unfortunatelty, my dad drove it up to the shop the other day and ruined the rear brakes so i just had to get new ones, we didnt replace the PB  so ill just never touch it again!

sounds like a painful trip!  Just carry around some good blocks in the back of the truck to use as a parking brake on the rear tires! lol... it works!

dont like waht?

wow... ren and stempy... that's from back in the day! LOL

In my old beaters it's the brake cable that causes this.Take your drum off and have a friend operate the e-brake, there is a lever that the cable is connected to, it should move with the cable. If there is no movement it's prob the rear cable but check if it's the front by pulling on the front cable (under the cab drivers side where the two cables turn into one) really hard by hand. If both rear cables move it's the front. Buy a book and the right tools (the best you can afford), it'll pay in the long-term.
