Do not drive the car. Have it towed to a repair shop and have the brake fluid changed.
No. Get it fixed as soon as possible. When you have brake fluid leaking out of your rear cylinder, you are putting lubricant on your rear brake. That is keeping that brake from working. It is also letting brake fluid drain out of the car. Your car needs brake fluid to stop the car. If you lose a lot of brake fluid, you will put your foot on the brake pedal and it will go all the way to the floor and nothing will happen. It can be dangerous when you drive down the highway at a high rate of speed and put your foot on the brake pedal and nothing happens. When you crash your car and turn it into a piece of scrap metal, you could get hurt.

There are three kinds of brake fluid in auto parts stores that you can use: DOT 3, DOT 4 and DOT 5.1. (There is also a DOT 5 "silicone brake fluid" the Army uses. Don't get that.) All Japanese cars contain DOT 3 fluid. DOT 4 and DOT 5.1 fluids can be put in the car if you have to - the three will mix - but DOT 3 is the most common and it's what I'd use if I was doing a fluid change.
