Hi
There is a switch under the brake pedal that presses down when you put your foot on the brake pedal, this iluminates the brake lights, they are plastic and do crak, when they crak the 2 wires can touch and this blows the fuse.
they are tricky to get at as you have to be on your back looking up into the drivers footwell, you should be able to feel it though, easy to do once you get to it, also try some wd40 on the switch if it looks ok.
Regards
Dan

You have a short in the lighting system. Try removing both brake bulbs and with a new fuse installed.. does it still blow the fuse? If not, then install one bulb at a time and repeat the test.. You probably have a short in or around the bulb socket.. Hope this helps
SOURCE: no brake lights blows fuse every time
there is most likely a short in the wires have you put a tow package on it if so did you splice in to the lines check all wires and see if they are burnt any were most likely short
SOURCE: Radio stops working. Why does the fuse keep
First is that the stock a radio. If it's an aftermarket disconnect any amplifiers, also if there's a power antenna disconnect that sometimes they become jammed. If you still blown fuses disconnect the radio and check to see if it's still blowing fuses. If not get a wiring diagram and find out what other things are on at circuit. It's a simple process of elimination. Good luck with that.

To Track down the problem you need to disconnect the Battery and use a Multimeter set to OHMS.
You are grounding somewhere. Start with the Brake switch and see if it is grounded. Then take off the wires to the switch. Check the wires going to the switch and coming from the switch. One side has to be the problem. Check with a parts place like Autozone or Oreillys for a Brake relay in the power box. If the power wire is grounded unplug the Brake relay and see if it drops the connection.
If it is a wire problem, keep tracing the grounded wire until you find a connection you can unplug to make the Ohmmeter drop. Remember the overhead Brake light on the roof. You may have just worked on the Taillights. The bad wire may be grounding in the roof or on the frame.
Once you isolate the bad wire you may want to run a new one.
