Hello all, I am pretty new here but I have a question on these braking systems. I have a 2014 f150 ecoboost FX4 crew cab and have been getting some weird problems out of my braking system.

I installed powerstop z36 brake pads and rotors recently because one of my rotors was absolutely destroyed (i am still not exactly sure why) The pads on that one caliper were all the way to metal and there was air in the line. (I bought the truck used and almost think they let air into the line so that the problem with that corner was unnoticeable). So i replaced all rotors and pads and replaced my brake fluid with Amsoil dot 3 and purged all the lines of old fluid and air.

The problem is sometimes it feels like they get stuck, like if i stop on a hill and move from braking to accelerating it catches like the brakes are still engaged, also I think one or more of the corners may be dragging sometimes as if they don't fully disengage. When I leave my house in the morning and disengage the parking brake and place it in reverse it will do the same thing where it sticks and then lets go after i accelerate.

Question is where should i start in diagnosing the problem? could a master cylinder or brake booster cause an issue with an individual corner? I have a hunch that it it one specific corner thats causing the majority of the issue because of the condition of the rotors when i removed them to replace them.

Thanks all

Hill Assist holds the brakes for up to 5 seconds after you release the brake pedal, but should release automatically as soon as the truck has enough power to start moving up the hill.

As for everything else you have described, it looks like you have a bad caliper with a stuck cylinder. It would cause the "The pads on that one caliper were all the way to metal and there was air in the line" issue you originally encountered and the dragging you are describing in only one corner.

Also, make sure that on the front brakes you installed them correctly. Bunny ears go on the inside where the cutout on the caliper is

Hahaha actually i did do this incorrectly the first time i installed them, but i caught it the next morning before i did any damage (I think) and fixed the issue.

I figured it could have something to do with hill assist, Is there any way to inspect the caliper? Or is it more of a just replace it and see if it fixes the issue type component?

It's bit tricky to diagnose, but here is a decent video.

It might be unrelated, but there was a safety recall on some 2013 and 2014 F150's due to the master cylinder. You might want to call a dealer and find out if your VIN falls under the recall.

I saw this and my truck has not had it done, Ive gotten it scheduled now. I also think that I may need a front left brake caliper so hopefully both of these things will fix my issues.

Thanks!

Here is another excellent video to watch. Make sure you did the brakes right
