I have added two large bottles of brake fluid and it drains slowly. No leaks from master or wheel cylinders or brake lines . Nothing is wet , no drips on the ground. Where is the fluid going?

Hi Gary,

More than likely it is going into the brake booster. At this point you will most likely need to replace the master cylinder and booster. Also, any other components after you retest.

Here is the procedure for the booster. More than likely you find the fluid inside. Let me know what you find and we can go from there. thanks
