I have to put brakes on my accord here shortly. I put in dot 4 fluid when I did the brakes last. My question is can I mix dot 3 brake fluid with the dot 4 without any issues?

Depends on the DOT 4 used. Some can be mixed with no probelems, some don't mix. If you have the old bottle see what it says, or buy a fluid like the Valvoline synthetic that meets both specs and can be used to top off either.
