When I pull my parking brake up it pulls all the way up till it's pointing straight up. Doesnt feel like it's really holding strong either. What needs to be fixed or replaced to get it back to normal?

 

Check to make sure the cable system isn't damaged. Under the car, just above the driveshaft in the tunnel, you'll see the parking brake cable assembly. It runs from the parking brake handle mechanism down towards the differential. You should see a "splitter", where the single braded line splits to 2 lines; one each running to the rear brake calipers.
