Stop in for a cup of coffee

Oh yeah, bring brake fluid. If you blow a wheel cylinder at least you'll be able to keep driving the car and have 3 of 4 brakes working.

Ask me how I know about old Mopars that have been sitting suddenly blowing wheel cylinders when you start really driving them again.

I lost 3 of 4 in a sudden slam-on-the-brakes moment at 70 mph on the highway once. Only that last wheel cylinder, the e-brake and sliding the side of the car 30' down the concrete dividing wall kept me from plowing into the stopped traffic.
