I have a 93 ford f350 diesel truck.
F350 brakes go to floor.
1 leak from brake line or brake caliper.
If the fluid is full then continue onto brake fluid is full down further in this guide.
Technically there are two main causes that would make the brake pedal sink all the way to the floor.
I have found no leaks.
One of the reasons is the brake system loses pressure from an external brake fluid leak.
The leak may coming from a brake line or one of the brake calipers.
The brake pedal will slowly under pressure go to the floor.
Ok when motor is off.
Check the brake fluid level.
Fluid doesn t seem to be disappearing.
The brakes were working ok but after bleeding the brakes all around i am now getting air in the system a read more.
If you hit your ford f 150 or super duty s brake pedal and it goes to the floor stop the vehicle and don t drive it until you find a solution to this problem.
The shop i had the work done at has no idea.

Reasons your brake pedal goes to the floor.
Using a flashlight check the level of the fluid or just remove the lid of the reservoir and look inside.
It will stop the truck but the longer you apply the brakes the more it goes to the floor until eventually it is on the floor.
The brake pedal goes to floor when engin is running.
That didn t solve the issues so i put in a new brake booster.
This article applies to the ford f 150 2004 2014 and f 250 super duty 2005 2014.
Anytime you have a brake pedal that goes to the floor raise the hood and locate the brake master cylinder s reservoir.
I replaced the master cylinder thinking it was the issues.
