Get a new turn signal relay.

So when you press the brake pedal you fry the fuse. You have a power short to ground.

But you don't have just 1 brake light fuse, you have 3 brake light fuses.

Let's look at them. (This is your underhood fuse box)

I color coded a box around each of them. Now let's look at the same color code being applied to the part of the brake light circuit which each of those 3 fuses protects. If you aren't used to wiring diagrams don't concern yourself with the entire diagram. It will make you dizzy. Just look at the part I color coded and start from Upper Left. 

See how the red colored circuit comes from the fuse labeled STOP LP and goes into and out of the Stop Lamp Switch on the top of your brake pedal?

See how that same fuse labeled STOP LP provides power to the fuses labeled VEH STOP (lower brake lights)  and VEH CHMSL (Center High Mounted Stop Light) when the brake pedal is pushed?

So what can you do with this?

Well, if the STOP LP fuse is frying (Red circuit) when you push the brake pedal, you can remove the VEH STOP and the VEH CHMSL fuses and see if it still fries. 

If it does then that's a pretty good clue that there's an issue with the brake lamp switch or its connector down there at the top of your brake pedal. Inspect the wires at the connector for damage, and if you find none, replace the brake lamp switch down there.

If the VEH STOP fuse is frying (Blue circuit) then that's a pretty good clue that you should inspect the wiring, connector,  and the bulb sockets (remove the bulbs) back at your brake light housing. Look for corrosion/rust in the socket.

And I'm just throwing this in there because this shouldn't affect your turn signal lights, but if the CHMSL fuse were frying you'd do the same thing. Inspect the wiring, connector, and bulb socket at the Center High Mounted Stop Light.
