Brake reservoir at MAX, start car, brake reservoir drains within a minute to MIN, turn off car, brake fluid returns to MAX slowly in a few hours. No leaks, stops good, may have been doing this for a long time…what is going on? Please include step by step instructions on how to rebuild the defective parts, include pictures/diagrams of my particular car. Where is the brake fluid going and how is it being pumped back? I replaced the front rotors and pushed out some reservoir brake fluid. I discovered this problem when looking for the reason brake fluid was on the garage floor. I my not do the work myself, but I need to know if the mechanic I choose can fix the problem without just replacing parts!
