If I am understanding you correctly it sounds like you had a trailer light assembly break and after that the brake lights stopped functioning and the blinkers now both flash at the same time.

Most likely what happened is that when the assembly broke it tore some wiring and now you have shorts between some circuits. If you check the wiring of the assemblies and clean up any shorts this should fix the problem.

I attached a help article on troubleshooting 4-way installs as well.
