The parking brake on my beast is much the same way. The lever is very sloppy and just plain worn out, as is the locking mech.
I have the lever & linkage off to pull the engine/trans & plan on fixing it then. I'm thinking I can have the lever bored & fit for a sleeve at the local machine shop to take the side slop out of it, the rest I plan on doing myself.


1956 GMC 370 dump " 'Tater "
1970 VW Volksrod "the Black Bomber"
2007 Chevy Avalanche
2020 Jeep Cherokee Trailhawk,
2005 Harley Davidson FLHTCUI

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion!
