Hi. I have a 2008 caliber SE with 94k miles. Recently my break light has be coming on and off. Driving without touching the brakes it will come on. A few days ago the light came on and is on all the time. The brake fluid level is full and with the brake pedal compressed it stays full. Brakes work fine and e-brake works and when I use the e-brake the light dings and flashes. I'm stumped at the cause. The wire to the reservoir is plug in secure. Any ideas? Thanks for your time.
