i just bought a $20 pressure switch out of parts unlimited and installed it. minimal brake fluid loss and only had to pump it a little t get pedal back. its cheap, looks clean and is super easy.
Install took all of about 10 minutes IF that... Brake fluid loss was none because as long as you don't push the rear pedal down and keep the cap ON the rear resovior you are fine. Screw the new banjo bolt on. Plug it in to the harness, then open the rear bleed screw and pump the pedal once. Close screw, lift up on pedal, open the bleed screw again and push down on the pedal... you fill the fluid that you just pumped out along with the very minimal air bubble or two and dump it back in the resoivor and your are done. Clean install and know that the brake light will always work and zip ties don't break off after a while... Wish I would have gotten it first than ****ing with the stupid ass spring.. shit, even on the stock rear sets I would have gotten the banjo bolt brake light switch.
