brake issues

hey i found out today that my master cylinder has no fluid in there..it was working great last time i drove it...the pedal travels to the floor due to no fluid...i cant find any leaks...i have checked out the front and rear brake at all connectors and clean and dry...no ABS system...just normal...not sure where the fluid went...it can still stop but its overall not safe...i think it might be my master cylinder but not sure...any help would be great thanks

Theres has to be a leak somewhere in the system. Brake fluid doesnt just evaporate. Refill the master and bleed the system. While bleeding it, check all over including line for leakage. If the master cylinder is leaking it will be easy to identify. Be careful with that stuff around anything you dont want the paint eating away from. Let us know what you find.

If you don't see the leak anywhere, even inside the rear drums, then check under the dash, carpet at the firewall just under the pushrod to the master cylinder. These can leak from their rear seal.

Note: I strongly recommend good quality lifetime-warrantied master cylinders (and clutch cylinders).
