Brake pump on 2022 gladiator got loud suddenly

[GR00VY]

I drove out to get some stuff from the store. When I got in my car (windows down) the brak pump was much louder than I have ever heard it. Before it was very faint and almost imperceptible but now it is loud. Only last for a few seconds but it happens every time I hit the brake pedal or release the brake pedal. I know for a fact it hasn’t been this loud before. I have had doors and top off and driven through drive thrus and other areas where sound will bounce and it has never made a sound this loud. Any thoughts on what is going on? I’ll be calling service department tomorrow.

you mean the brake booster or the master cylinder or the ABS pump?

Not sure. All I know is under my hood a loud hissing sounds when I step on the brake pedal. Lasts about 2-3 seconds and then stops. Wasn’t there before yesterday.

Here is a video of the sound. Never heard it before. Had the truck for over a month now. Had windows down top and doors off and never heard it. It could be normal I don’t know.

Went to the jeep dealership and they said it is operating normally. It is the booster engaging as it should. Just must have never paid attention or noticed it before

Mine sounds nothing like that. And dealerships are known for being incompetent AF. They can’t even be bothered to put oil drain plugs on tight half the time.

Mine doesn't sound like that... But I have had a a mysterious sound at times

Mine sounds almost like metal grinding and the pedal feels like it gets softer but I also feel the "grinding" in the pedal. Doesn't happen all the time and I haven't figured out a pattern to it. Hard to take it in if it's not consistent. Shesh
