Default ZR2 Brake Q?

Newbie here, hoping somebody has some input...
My g/f's Chevy ZR2 has rear disks. "Something" was smelling awfully nasty when she pulled into garage after a 30 mile drive.
Slipped under then rear drivers side wheel and noticed a spring loaded line was no longer connected too the lower half of when i think was part of then brake system.
My novice assumption isn't , the calipers close then pads onto then disk when brakes applied, and this "spring loaded line with a plastic loop connector" was perhaps some kind of "brake release assist" ? and wasn't working up too par being no longer connected.
I figured one of you probably know exactly when i'm referring too , at least it's my hope.
Slight occassional sqeek (relative too radio volume...lol)
She had then bearings replaced and a brake job both last fall. Some circumstances led me too think then wrench wasn't overly sharp/thorough.
Vehicle seems too roll/coast fine with no apparent drag.
Any clues anyone?
TIA!

The 98+ 4x4 S10/Blazers had rear disc brakes with an internal drum parking brake. The parking brake is actuated by a cable that youve described. With the cable disconnected, the parking brake shouldnt apply.

If you want to check it, pull the wheel, pull the caliper, pull the disc, and you'll see the drum brake shoe attached to the backing plate on the axle. You should be able to tell from the wear marks if its hanging up or not.

Something that Ive seen pretty commonly on these trucks is dirt, grit or even stones ending up between the pads and the rotors. That can give you anywhere from a grinding sound, to a weird smell, or nasty groves in the rotors.
