If vehicle has no signs of failure, such as smoke, steam, different gauge readings, system should be checked to be sure, If light is flashing, do not drive, catastrophic damage could occur.

Have car towed to our shop, tell the tow company we are closed, they will keep it for the night and deliver it when we are open, or they will place it on the street near the shop.

Yes you can, the squeak is usually the low pad sensors, but sometimes brake pads wear at an angle and you do not have a few days before a brake rotor is so badly damaged that it must be replaced, at a much higher cost.

You probably have warped front brake rotors, usually caused by over using brakes such as riding brakes down a hill, coming up fast to a stop and then holding pedal down hard, or rotors are worn to minimum thickness. If when applying brakes vibration is livable, you do not need brake work, I would have brakes inspected to be sure.

A good wiper blade should clean your windshield in one to two passes, it should be as clear as just washed glass on a warm day  Blades usually need replacement every 6 to 12 months
