I get in my truck this morning, start it up and head out for work. When I go to make my first stop down the street, the brake pedal goes all the way down and the brakes just barely slow the car down, much less stop it. I pull the emergency brake to stop, slowly drive the car onto the parkway of a neighbors house and check under the hood.
The brake fluid reservoir is completely empty. Not a drop of Dot 3 in the damned thing. I feel around the reservoir fittings and all around the master cylinder and its connections and there isnt a drop of brake fluid anywhere so neither is leaking fluid.
I follow the hydraulic lines from the master cylinder though the engine compartment and under the car and there appear to be no kinks or cuts or breaks on those lines.
When hydraulic fluid is leaking from the brake calipers, it usually drips onto the brake assembly and tires. I check all four brake assemblies and tires and find no evidence of hydraulic fluid on them.
I walk over to the driveway where the truck was parked and there appears to be no evidence of hydraulic fluid on the asphalt. Even though it has been raining for over a day, there are no swirls on the adjacent wet areas that would indicate a fluid leak.
Now, I ask you, where the hell did my hydraulic brake fluid go?
