If there is no evidence of a leak, it's not brake fluid. The routing of the har brake lines and that they're metal makes it unlikely that it's a leak from them without some sort of damage.

If you want to test it for a leak, park the car, leave the engine on and idling, then repeatedly press down hard on the brake pedal and hold it each time for several seconds. After several minutes of that, the pressure on the brake fluid would let it find any small holes to leak out of and you should see brake fluid on the wheel(s) or ground if there is a place to leak. Look under the car first for fluid before moving it so you can exactly figure out what part of the car the fluid is over.

If it is near the wheel or caliper then fluid would be collecting on the barrel od the wheel / rim...?

Any leaks from the caliper bleeder valves and the brake line connection would end up on the inside of the wheel. If enough leaked that it would end up on the floor. The brake fluid would have also left quite a stain on the wheel mixed with brake dust so it would be easily visible.

I had a rear caliper seal fail and I found it by the brake fluid that leaked off the wheel and onto the floor.
