I have a 1996 Astro. The parking brake is sticking, had it checked out, and it's super rusted. Located in Seattle so lots of rain right now. Looks like it needs to be replaced, but the part is discontinued. Part: https://www.gmpartsdirect.com/oem-parts/gm-parking-brake-control-15711781?c=Zz1icmFrZXM...
