2025 Maverick - brake pedal release clicking noise

[TheShark]

When I brought mine in they checked it out and ordered the EBB. I waited a week for it to arrive and then brought it back, they had the Mav for a day but I had a loaner.

Are you referring to the swoosh sound or the clickiness ? Forgot to mention this is with truck turned off

Had the same thing. Needs a new EBB. Mine was replaced and no more noise.

Just got back from the dealer. It’s the electronic brake booster. They just ordered the part to replace.

Did the new EBB fix your issue?

Yes it did

Yes it did

Thanks. I’m just worried a new ebb will be making click sounds soon after like the fist one eventually did.

Hello,
Got the truck a few weeks ago, now 600 miles in a weird clicking noise developed when I release the brake pedal. I don't think the noise was there when I drove the truck off the lot but I can't be 100% sure. Please see attached video I took with phone on the floor and camera facing the pedal assembly. It sounds like some where needs some extra grease but I can't pinpoint the source. I listened from under the hood with somebody pressing the pedal inside and I can hear it faintly.
Any hints or things to try myself before I take it in ?

Do you have that damn brake hold thing on? I find it a nuisance.

I’ve been good since July. Knock on wood. The tech even replaced the pin that connects the piston with the brake pedal.

OK , I did more investigations before going to the dealer, at least I can give them some hints. Now I'm confident that the noise does not come from the brake pedal assembly since the noise is not there if the car is completely off (not even brake lights come on when pedal is pushed).

The noise is from the engine bay near the brake booster / master cylinder. I can forget about an easy DIY fix.. bummer
