1990 80 G54 rear emergency brake mechanism

[Cody Forbes]

The calipers are notorious for this. The only real fix is rebuilding or replacing them. I did my first set (after just not using the parking brake for 10 years lol) earlier this year. Not too bad of a job, but for a first timer you should plan on it being an all day affair. 

The problem is that the seal under the lever where the cable attaches is bad and moisture gets in and rusts the innards. Somehow the bad seal keeps lubricant out very well; I've never had any success lubing a sticky caliper.

Rebuild kits come from Big Red in the UK. For me shipping was free, not sure if that applies to remote islands ;-). http://biggred.co.uk/

I used a guide that I found on one of the urS forums via google. My 5000 caliper was slightly different, but close enough.

I lay behind the rear wheels and watched the parking brake being activated. One moved a lot the other very little and when released the good one opened or unclamped quickly, not the other.
