Your rear brakes on a 1999 Chevy Lumina may not stay adjusted due to worn brake shoes, a malfunctioning self-adjusting mechanism, or issues with the brake hardware such as springs or clips. Additionally, if the brake drum is out of specification or there is contamination from oil or brake fluid, it can prevent proper adjustment. Regular maintenance and inspection of the brake components can help identify the exact cause and ensure proper functionality.

Apparently your rear trunk latch needs adjusted.
I have a 1999 Suburban-JB6 brakes. The drum size is 11"
go to napa or auto zone and if they don't have it go to a chevy dealer

I'm going to bet they are drum style brakes. I have a 1999 Luminia, and they are drums on it.
Brakes are shot or a wheel bearing is bad.
Service brakes - replace Master cylinder Parking brake- either lubricate or replace cables ; I had a similar problem with my 1999 Chevy blazer, i ended up replacing the caliper and have had no problems since.
Someone may have switched the sockets in the back of the lenses.
Our 1999 Chevy Lumina car - 3.1L at 150k miles has been very reliable, to date replaced alternator, reg tune up items (belt, hoses, ect...) and brakes.
Bring to a shop that has an ABS scanner to determine the problem
First make sure that service brakes are adjusted properly Adjustment is located under the vehicle at the junction of the cables Set brake to 3 clicks and tighten adjuster so vehicle is "held" at that point
