1990 Acura Integra 4 cyl Front Wheel Drive Manual 285184 miles
I have noticed that the ABS brake fluid reservoir is over full and the master cylinder resrvoir is al most empty. I have not found any leaks in the brake system. I can only assume that a return line to the master cylinder is to blame, but I don't know if such a line even exsist on this car. What could the problem be and what are the troubleshooting steps I will need to take so I can find and fix the issue?
