[belt squeak and ac]

hey guys ive read up a lot about the belt squeak on the 6.0s but im still a little confused. this morning i started the truck up and the squeak was still there, i stayed and listened for a little bit and it was cycling with what sounded like the a.c compressor. it would kick on and squeak and then kick off and stop. now my question is what would cause the a.c compressor to cycle when i had the heat all the way up and no a.c on? the a.c seems to be working fine in the truck otherwise? thanks in advance

That's correct...new purchase and unknown history. I'll look into the brake bleed

[Brake problems]

Hey guys. New to the forum and to the sss world. I've searched countless posts but I wanted another opinion

 

Truck is 04 awd sss with disc all around.

 

Braking seems very diminished overall with a spongy pedal feel

 

When I pump the brakes with truck running I can't build any pressure...with the truck off after 3 brake pumps the pedal is rock solid...when I come to a complete stop I can continue to push the pedal to the floor bud it does take considerable effort to do so. Any ideas? Thanks in advance
