Like many others that I've read on here, my parking brake was in sad shape and getting worse. I didn't really understand how the system worked so I just kept trying to tighten it every year to pass inspection until this year one bell crank was completely seized and the other very close. The guy at the shop wouldn't pass it even though it would hold the rig, but he really did me a favor because next year I would have had to cut these out and replace everything. I wasn't able to find a lot of info on here so I took as many pics as I could with gunk coated hands to hopefully help others.
Here's some supplies:
-At least one full can of PB Blaster (maybe two)
-Permatex extreme temp brake grease
-Various punches, pliers, prybars, hammers and mallets from small to large
The pics aren't really in order and I didn't get a lot of tear down pics since it was dirty. It comes apart fairly simple though.
-Remove wheels, calipers, rotors and shoes/hardware (if you're not familiar with it, take a picture or do one side at a time to remember how it goes back together)
On backside of backing plate:
-Remove springs on brake cable/bell crank
-Remove small retaining pin, remove bigger pin with punch
-Remove two small bolts
On hub side:
-Disconnect cable from shoe lever
-Remove c-clip
-Remove pin with punch
-Remove bell crank from vehicle
*All the remove steps were not as easy as it seems. Mine was rusted pretty bad so it took LOTS of PB spray and working on something else while it was soaking, giving another shot and so on. Once everything was apart, scrape, brush whatever you can do to get rid of the rust. Then coat everything in some good grease. The permatex is used by a lot of racers and it says it stands 3000 degrees. Then just put it all back together.
-Adjust shoes (tighten until contact with rotor, then back off a little)
-Adjust bell cranks (adjust little bumper thing to take up slack from shoes)
-Adjust hand brake side inside cab (take up slack in cable/test to make sure it holds vehicle in drive)
