Unlike some earlier models that activate a drum brake inside the rear rotors, the '89's emergency brake locks the rear disc brakes. I'm guessing that you're have a difficult time getting the emergency brakes to release. I've found the best way to set/release my '89's emergency brakes is to first step on the brake pedal and then while holding the brake pedal down engage/release the emergency brake handle.
If this doesn't resolve the problem that you've having, try posting a better description of the problem in the C4 Technical/Performance forum.
Good luck! Hope this helps.

I have a 19 GS with 6500 miles and i'm starting to feel brake pulse at around 40 mph when slowing from interstate speeds. Any ideas on this? I can't imagine I have a warped rotor, these cars are designed for tracking which this car has never been. So it's hard for me to believe I have done that!

Sounds like a warped rotor to me. They dont make them super thick anymore where you can keep turning them unfortunately
Maybe check it..unless you ride the brakes a lot at 6500 miles that shouldnt happen

A lot of people think rotors warp, they may but it is very unusual. Heat checking and cracking are more likely.

If the car is new to you, push the button in and while holding it depressed lift up on the handle, then back down.

its hard to imagine anything would overheat from that. also steel/iron turns blue pretty exactly at 300°c. i dont remember any of my rotors being blue, maybe thats because they get much hotter?
and 4000 miles? you probably do spirited driving on the street and those autocrosses. imo thats just normal.
(disclaimer: i dont have a c7 and have no idea about the pads it uses. i also suspect "original" might mean different things unless they really came on the car when new.)
