When u push in the parking brake it just comes back up. it won't stay down...?
Most parking brake pedals work with a dog and pawl , much like a row of saw type teeth that have a small pivoting stop which catches in the teeth to lock down the pedal. If the pivot does not fully engage to teeth because of dirt or rust the pedal will return to its original position. This may also happen if the release cable in not fully returning. You can try pushing on the release handle rather than pulling and see if your pedal now locks in place. You can lube these parts with a can of spray lithium grease but be sure to protect your carpet and pedals so they do not get stained or become slippery. Mask areas off with newspaper or cardboard. Work the pedal and release cable a few times. It will usually free up any binding parts. I hope this helps!

Test for power at the inoperative bulb socket with a 12V test light

Some poor soul will have to get upside down under the dash and spray wd-40 on the brake linkages. If it doesn't free up you could check to see if the master cylinder is sticking, or maybe the push rod from the power brake booster is sticking. Get the Chilton's book on your GMC to see what is where, and any hints it may have.

have you checked the fluid level? Make sure that the master cylinder is full of fluid and that there aren't any puddles of brake fluid under the vehicle. If there are no leaks and the fluid level is ok, I would have to guess that the brakes were not properly and/or completely bled of air. If it feels as if there are no brakes at all then I would have to think it may not have beeen bled period. All 4 wheels, in this case, should be thoroughly bled.
SOURCE: parking brake pedal will not
the latch assembly either broken or stuck open
I have successfully lubricated some and they started working
there is a little latch that holds the teeth in the park brake assembly you have to gain access to see this latch and see if it is struck or simply broken
Hope this helps, it it does please leave feedback and vote Thank You and Good Luck

Check the parking brake cable to make sure it is moving freely and allowing the brakes to completely release when you pull the release lever. Sometimes dirt and rust will lock the cable. In this case, the parking brake pedal will still sit on the switch even though it is unlocked because the spring can't pull it and the cable back to the off position.
