No leak found, but brake reservoir empty?

[Steven_fanlu]

Hey, My m37x brake pedal was going all the way to the floor, reservoir was empty, but I seem to find no leaks yet. I'm checking all the obvious places. Any help on this?

well logic would tell me if there is none in your reservoir its all in your calipers and lines. what do your brake pads look like?

It definitely leaked out somewhere. Since you have air in your system, you must bleed the master cylinder properly followed by each brake line in proper sequence. You may also have air in the ABS module which will only be fixed at the dealer.

Agrees with Armed Aviator. If you remember seeing it full and now it's empty it had to have leaked out somewhere. When you apply the brakes do you have any stopping power? Also, if you were that low the brake light should have been popping up on your dash. You might want to check to make sure the light isn't out.
