Mechanical Problems/Vehicle Issues and Fix-it ForumIf you've got a problem you just can't figure out, a noise you can't diagnose, or a Check Engine Light that won't go away, ask about it here!
I had been experiencing a loss of brake fluid from my master cylinder reservoir for a while. So, two weeks ago, I had my mechanic look things over and he replaced a brake line that he said was leaking. Today, I got in my car and the brake indicator light had come on again. I checked the resorvoir and it was low . So, I pulled the brake line covers (guards) off and my dad looked at the lines while I pushed the brake pedal. No apparent leak. Also, I pulled all four wheels (looking inside the drums in the rear), and also no apparent leaks. And, there is nothing evident under the hood at the master cylinder or inside the car near the firewall that I can see. Do you all have any ideas on why the reservoir is still losing fluid? Thanks a lot,

P.S. One other brake line is pretty rusty, so I will replace it, but even it did not leak during our tests.
There is no dampness below or within the brake cylinders (I peeled back the rubber boots to check inside them). How would I determine if the master cylinder is leaking into th firewall area? Thank you,
Can you tell me what this gizmo is? Is has an empty length of line running to it that runs along with the brake lines to the rear. This component is under a little plastic guard right near the front left edge of the gas tank.

Stick your head under the dash and look.
