I drive a 2004 Nissan Xterra. I’m originally from Florida, but have been living in Quebec for just over a year. About 3 weeks ago I started out to run some errands and as I was pulling out of the parking lot the brake light came on. I pulled over and depressed/released the parking brake a couple of times and it stayed on. I proceeded to run my errands and after about 10 - 15 minutes the light went out. The brakes seemed to be working normally the whole time I was driving. When I got home I checked the brake fluid level and it was about halfway between min and max.
Since then the light has come on three more times. Each time the outside temperature is below 15F. It does not come on when the temp is higher. After driving for a short time the light always goes off.
Could there be freezing in the brake lines? Should I have the brake fluid flushed and replaced? I’ve searched my recommended maintenance schedule and this doesn’t appear anywhere in it. The recommended brake fluid for my vehicle is DOT3.
Thanks for any insight.
