Unbolting and removing the caliper gives you access to check the sliding pins.

 

Pins were free and not stuck at all. My thread on my issue is below so I don't derail the OP's thread any further.

Just replaced the pads all four wheels on my 2015 5.0. at 50K miles. Each wheel had significantly more wear on the inbound pad. These were original factory pads. Felt like the pad itself was hanging up in the carrier. All dog ears were in the correct inbound position. Almost seems like too little tolerance between the pad backers and the carrier. I made sure to pull the pins and clean/re lube as well as putting lube on the pad backer where it contacts the carrier.

Will check in 10k miles see it it's evened out...

 

Mine were harder to remove from their slides than they should've been as well. I'm having to replace the front rotors when I do the pads because it grooved the rotors.

 

You probably should consider replacing your slide pins. This video has some nice quick tips

 

There will always be a bit more wear on the inside pads. The grease around the slide pins creates a seal so that air gets trapped between the end of the pin and the hole it sits in, which resists movement of the pins. This is why there are so many pins that go bad. There's a balance between having enough grease to keep water out and having so much grease that air can't migrate past the pin. Well, not really a balance. There's a wide gap between having one Vs the other. You either grease them well and deal with the inside pads wearing faster, or you have stuck pins nearly every pad change.

Sadly, a secondary small hole running from the front of the slide to the rear would equalize the pressure and they could be greased halfway to heaven, eliminating all issues and permitting perfectly equal pad wear. But not having one is 'good enough'.

 

Without warning I starting getting an awful grinding noise Friday night. Truck wasn't pulling and there was no chirping or any other noise prior to the grinding that happened. I replaced the front and rear pads and rotors at the end of March too which is unfortunate. Upon disassembly I found the front passenger outer pad was totally shot. It wasn't evenly worn, the top of the pad was right down to the metal and I found the boot was all torn up. Other than the few hundred bucks I wasn't expecting to drop, it was a breeze. I went with a NAPA reman semi loaded caliper. Came with new hardware. To note, it was painted black and the paint seems pretty decent. The color doesn't match the drivers side caliper but I could honestly care less. My truck gets maintained but it gets used as a truck so those little details don't bother me.

 

That's a pretty clear indication of a bad caliper. Yikes.

 

I replaced front and rear pads at 63k on my 15. Did a test run and front brakes were extremely warm. Long story short, both front calipers were hanging up. Got Ford reman with lifetime warranty at Auto Zone. After install problem was gone. Calipers came with new sliders and boots.

 

I need to replace my rear calipers with electric parking brake
after going into service mode
Do I just unbolt the Motor from the calipers
replace and bleed calipers then just bolt the motors back on and go out of service mode?
