Another brake issue

While applying brakes I get a constant knocking sound. The speed of the knocking is relative to how fast I'm slowing down. The sound use to be spuratic but happens all the time now. It's actually starting to get pretty loud and I can feel a vibration in the brake pedal after each knock as well. The jeep is new to me and not sure when the last time the brakes have been worked on. Seems to get worse the more weight in the jeep.

Also, sometimes on the first drive of the day the brakes seem to grab for a split second and then release. My driveway is sloped pretty good which is where it usually happens. Doesn't happen ever time, mostly on the first drive.

What do you guys think. Fixable or should I just turn up the radio.

If you can feel it in the brake pedal I would lean towards a warped rotor.

Very common for the rear brakes on these vehicles to be (sticky) when you first drive off.And I agree on rotor warpage

I'd pull the wheels and look for loose brake pads or even a cracked friction pad, check the rear shoes for broken self-adjusting cable, crack friction pad, broken retaining spring or nail and if the hardware looks in good shape, spray eveything off with some brake cleaner, either have the rotors resurfaced or replace them.
