No pressure at brakes they go to the floor?

Ford is the only manufacturer that is still using the miserable rear calipers with built-in parking brake assemblies. You have to work the parking brake to run the pistons out to the pads. Those pistons do not self-adjust like the front ones do. You may have to remove the rear calipers and hold them in various positions to get all the air to bleed out. It gets trapped inside the pistons. Simply bleeding like on the front will not work. Ford is also well-known for their parking brake cables rusting tight in a year or two. If that has happened you'll have to use a large channel lock pliers to work the parking brake levers on the calipers.

Thanks for the reply.
Even though I did not disconnect the calipers, I still have to bleed the brakes?

Sorry for the confusing information. My reference to bleeding the air out has to do with replacing those calipers on Fords and older GMs. All you need to worry about is adjusting the pistons out on the rear calipers. That is done by working the parking brake repeatedly until the pads contact the rotors. You can do that to each caliper with a big pliers if the cables are rusted tight. Once you have them adjusted they will continue to self-adjust from that point on as the pads wear down.

I just recently replaced rear brake pads and rotors on the car listed above. I replaced as normal, retracted the caliper with special tool, etc. Replaced both pads and rotors. When driving the vehicle the brake pedal is very soft. When you first press it starts to brake, but in order to stop you have to depress the pedal all the way to the floor. I researched and found that according to Fusion Instruction Manual for brake replacement the first step was to disconnect the parking brake cable from the brake caliper and remove the cable conduit clip. Could this potentially be the cause for the soft brake pedal? There does not seem to be any fluid leaking, and have tried to pump brakes with brake fluid cap off to "old school" bleed the brakes. Is there anything else I should be considering or looking at? Help!

Hello my name is Dave.

The first thing I would do would be bleed the brakes since the most common reason for a soft pedal is air in the system. Here is a link to our tutorial on how to bleed brakes:

I am also including a link to our repair guide on when your brake pedal goes to floor.

https://www.2carpros.com/articles/brake-pedal-goes-to-the-floor

If you can bleed the brakes and go over the repair guide for the pedal going to the floor and let us know the results we will be happy to guide you further

Please keep us up to date on your progress and thank you or using 2CarPros!
