Help! 2005 BMW 530i Sport Package brake issues.

Hello, need help. I bought a 2005 BMW 530i about four months ago from a Acura dealership in Fairfield, Ca. They replaced the pads and rotors. Last night while driving home from work the ABS light warning came on and the screen stated Don't drive excessively or stop. The brake pedal went to the floor and the car drove very slow. Pulled over and turned the car off. Turned back on and put it in Drive, the car wouldn't move as if the brakes were locked. Turned off again thinking it's a computer malfunction and restart the car. Now the brake pedal went to the floor to stop. Limped home and got the car towed to a shop the next day. The shop reports there is petroleum fluid in the brake reservoir and the hoses are swollen. Towed it to the Acura dealership and they say they didn't top off or bleed the brake system. Can you change the brakes and rotors without topping off or bleeding the brake fluid system? Any help would be much appreciated!
