Kodiac Brakes

I also have a 2013 Mobile Suite.GM need a special module but not Ford or Ram. Those brakes work very well but from my experience the pads which are 1998 Buick LeSabre are a fairly small pad . If you pull off the wheel and look down from the top the pads will look unused. However if you remove a caliper for a closer look the pads could be completely worn out. They sit higher than the rotor and wear beneath the top of the pad. I have changed mine twice and keep a spare set at home. It is amazing how strong they brake considering how small the pads are but with that in mind they are fairly short lived. That would be my first check assuming you can hear the pump if you pull your brake away pin.
Don't leave the pin pulled longer than a listening test as Moryde burnt my switch bleeding the brakes. Good Luck
