Brake fluid leak HELP!!

i have a 2000 f250 7.3 ltr diesel with 133000 miles...there is a brake fluid puddle on my driveway coming from fluid leaking on the driver side under the hood somewhere...i cant pinpoint the leak but the wiring harness that plugs into the abs sensor is wet. The fluid falls down onto the inside wall of my tires and it flings it into my finder well...it seems like it only leaks when its really cold outside...i do live in louisiana so cold is like 30 degrees...anyone else experience this problem? what do i do before i have to spend a bunch of money just for someone to tell me what is wrong? Cant find the leak

How do you know it is brake fluid?

Was it just spilled and could it be nothing wrong?

At least, post pics, color of fluid, odor etc.

Could it be ATF? / PS? fluid?

What side wheel is fluid on the sensor? If its driver side, it could be master cylinder. Really common for seals to go out in them when weather changes.
Should be evidence running down brake booster where master cylinder attaches.

Could be caliper, if thats the case, the inside of the wheel would be all wet.. Could be brake line to caliper. Just about everything would be wet near it but should be able to see with someone pressing on the brakes.

Be careful.....brake fluid is extremenly flammable and will burn that truck up quickly if it mists to a hot exhaust component
