Yes, you can, but there are enormous risks associated with doing that. For instance, when your car is low on brake fluid, the effectiveness of your brake is not assured, which means that the car may not either slow down or even stop when you want it to, which is a panacea to a reckless accident capable of affecting you, other road users and all your vehicles. Therefore, it is only reasonable to understand that doing so comes with enormous risks, and so it should ( or rather must) be avoided as much as possible.
What does it mean when your brake fluid is low?

Drivers living in areas that get winter weather should also inspect their brake system frequently, as salt and other contaminants can get into the brake fluid.
Why does water in brake lines cause corrosion?
Water in the brake lines lowers the boiling point of the fluid, so stopping ability can diminish in hard stops as heat in the system increases . In addition, over time the moisture can cause internal corrosion in the brake lines, calipers, the master cylinder and other components.

Why do brakes make a grinding noise?
This is dangerous. It reduces your stopping power significantly; your brakes won't slow the vehicle adequately or possibly not at all if you let this go on for any length of time. This situation will also destroy your brake discs and possibly cause the brake system to fail entirely. Have any squealing or grinding noises checked immediately.
How do brakes work?
Disc brakes slow and stop your car by using brake calipers (they're like large, adjustable clamps) to squeeze brake pads (they look a little like hockey pucks sawed in half) against the brake discs, also known as rotors (Frisbee-sized metal discs). When you push the brake pedal, it causes the calipers to clamp down on the brake pads, which squeeze the rotors, transferring the kinetic energy of your car into thermal energy— heat—via friction. The friction created is what cuts the speed and brings your car to a halt. As the pads rub against the rotors, they both wear down slowly; the black dust you see on the wheels of some cars is the residue from the pad material and steel rotor that has worn off. Brake pads are an integral part of your car's disc-braking system, and making sure they are in good condition is crucial to your safety.
What does it mean when your brakes are grinding?
As noted above, if the pads have completely worn down, you will soon hear a grinding sound that means the pads' backing plates are making contact with the brake rotors . If that happens, get ready to pay big bucks; you'll need to replace chewed-up brake discs.

So, although it’s still not great to be breathing in the current material, the compounds currently used are indeed safer than the brake pad material of old.
Why do cars have holes in their brakes?
