Replaced Electrical Outlet-- Main Breaker Tripping

We have a regular dual receptacle and all of a sudden the bottom half stopped working. I took out the receptacle and saw there are 4 wires--red, black, white & bare copper. The part of the receptacle where the red wire was attached was charred, and the wire itself is a little bit black at the end. I bought a new receptacle and attached the wires exactly as they were on the old one-- black & red in the copper screws, white in the silver, and bare ground wire in the green. Now when I try to use the receptacle, neither outlet works and it trips the main circuit breaker.

What is the problem? Could it be the red wire, since it is a little burnt at the end? Also, I couldn't get a tight fit on the ground wire in the green screw-- could that be the problem a well?

Look at the old receptacle, is the brass tab between the brass screws broken out? If so, you need to break it out on the new receptacle - brass screws only, not the silver screws.
My electrical answers are based on 2014 NEC, you may have local amendments.

Did you look at the old receptale due it is a split set up and to order to work properly you need to break the tab between the two.

Did it trip just one breaker or two breakers ? if two then I know you have two diffrent circuits run in there.
