It had come apart towards the front where the cable adjustment is. There was a cobble job involving a turnbuckle and rope clips in place of the threaded adjustment rod, I put the factory style parts back.
I've replaced the calipers on the back, but never pulled the rotors thus have no clue what condition the innards are in.
I didn't think to check whether they were still riveted.
From what I've read today after searching, the parking brake is of marginal usefulness at best? Probably not effective enough to consider useful if the service brakes fail?
If that's the case I may leave well enough alone until I have reason to pull the rear rotors or until trailing arm rebuild time comes.
