Rumble when braking

[HMMWV V]

So my M998 just started having this major rumble when applying the brakes. It doesn't happen all the time. Seems like it happens when I have been driving awhile. Also at low speeds I hope someone can help. Drive fine otherwise. Thanks again for input.

Has any work been done to it lately? My instinct is to blame the brakes. Warped rotor? Stuck caliper piston? Stuck pad? E-brake not fully disengaging?

No work done to it. But will investigate. Is this a common problem with this vehicle?

Have you fully inspected and serviced the truck??? all filter and fluids including the diffs and gear hubs been changed? Have the half shafts, brake rotors and pads been inspected? including the half shaft/rotor bolts?
That would be the first thing to do if you have not already done so, if they have been competently inspected then any issues should have been uncovered.

If she sat, it could be rust

Will do. Thanks for the advice.

Rear brake chatter is common after new pads and lasts for some time, even when pads are beveled and burnished correctly, if it just came out of no where, check your Halfshaft/rotor bolts, caliper bolts etc…
