You asking about the parking brake shoes? It's a royal pain in the ***, took me an hour and a half and it came down to finally calling my dad over to help me, because 2 arms at full strength weren't enough and that was only one side. The other side I went to do, and realized I have a leaking rear axle seal, so I decided to hold off and just adjusted it out a little then cleaned the ever living piss out of it with brake cleaner until I have time to get to the axle seal. At that time I will put new shoes on that side. That was my plan for today, but it is pissing rain and I refuse to work in the rain - I grew up in Western Washington and hate it with a passion.
Or are you asking how to replace the parking brake inside the cab of the truck (just realized this was in Interior Discussion). lol.
