2001 - Brake Fluid Level

My son has a 2001 GX? Whichever version is the 4 cyl economy one. And I mean economy. Pieces fall off of the interior of this thing all of the time.:frown: Anyway, it has about 70k on it. He's been delivering pizza now for a little while so he's been putting some miles on it as of late.

I changed the front brake pads about 19k back. Didn't change the rotors or get them resurfaced. I was told by the previous owner that they changed the front rotors once already.

In the past few months, I've had to add brake fluid every 2 or 3 weeks. I see no leaks around the master cylinder nor do I see any spots where he parks. It's like the stuff is just vanishing. The brakes are performing well according to him. Had the front tie rod ends replaced a few weeks back and the service guy advised the pads had about 30% left.

With other vehicles I've had to add fluid any time the front pads get low. But never as often as this. Any advice as to where this vehicle is prone to develop some type of hidden leak in the brake system? Or am I worried about nothing and just nearing the time to change the pads and rotors?
