1996 toyota paseo is leaking brake fluid and the front brakes are really soft to non existant. Brake light was constantly on so I checked the brake fluid level and filled it. Next morning the brake fluid was empty and the braking system was not working. Tried to find the problem but was not able to locate the leak. Any suggestions or has anyone experienced this problem before?

This job need 2 persons. You must take of all 4 wheels . Must see a cooper pipe on each wheels witch goes inside to a pads brake system. Here somewhere must be a screw for to take of the air from installation, unscrewed. One persons must push the brake pedal every one second up to coming out the brake liquid. When the liquid is go out without air, stop push and strongly tie the screw back. Do this for all 4 wheels.Do not forget to fill up the break liquid tank. After that if is still lose the liquid, fix something white, paper or something like that, under the car on a flat place and leave for a wail to see where the liquid goes. Possible to have a pipe broken. But my idea is to go to an authorized service. You can't play with breaks.
