Brake strange noise when sharp turining

Philty44

Hello,

I've received my Bronco Big bend 2.7L 2 weeks ago. There is a strange noise when sharp turning. The brakes are making a squeeaking noise. I went to the dealership today, nobody could help me. Nobody knows what the issue is...


thanks!

I have heard this as well. It sounds like the noise when trail turn assist is in use. When I heard it, I was not turning, but applying the breaks while going down a hill sliding on ice. For me, trail turn assist was not activated.

Turn assist wasn't on. Here it's winter, it does it a lot more when turning on the snow.

Sounds like a tire rubbing against the disc brake shield.

I'm feeling it's related to whatever the mechanisms are for Trail Turn and Traction Control. I'll do some snow testing tomorrow. The northeast is gonna get hit big.

Even if I remove all the tractions control it still does it. I think it's related to the ABS system. From what I have heard from other people from the North Pole (Quebec, Canada) , it only does it with the 2.7L engine. The brakes system isn't the same I guess.

So go at low speed in the snow, do a sharp turn. As soon as the truck loses traction you will hear it and feel it. You can' t miss it.

Any update on this? Mine has done the same thing since day one.

Have you tried other For dealers? What did Ford tell you when you sent them a DM ?

Bronco 202?

That’s my last choice based on experience and other stories. Going to use for scan to change tire size and see if that changes. Bronco is an 2021 and only has 3500 miles on her. Upgraded to 37” tires after 500 miles. If that doesn’t work then I guess I’ll drop of off with Ford.

Hi I just recently bought my bronco and am encountering the same problem it is lifted with 35s I’m thinking this maybe has something to do with it. Did you ever find out what the issue was?

I noticed mine did this also in the winter when turning and sliding on ice with trail turn assist off. I think it is AdvanceTrac electronic stability control (ESC) working or trying to correct traction. It works with the brake booster which is electronically controlled. The brake pedal position, I think is read by a position sensor also. When turning in conditions with compromised traction, the AdvanceTrac tries to keep the vehicle straight. To do this when turning on ice or snow, it will apply the ABS with feedback from the wheel speed sensor from the wheel that it is trying to straighten, depending which way you are turning, even without the brake pedal pressed. The computer is getting real-time feedback from the wheel speed sensors, brake booster data, etc. and corrects real time. The sound it makes is the system working. It is not a familiar sound if you have had an older vehicle with a hydraulic brake system. You can turn AdvanceTrac (ESC) off by holding the traction control button for 5-10 seconds. A message will pop up on the dash, stating it is off. Once you do this, ESC is off, traction control is off and the computer will do nothing to help the vehicle gain traction (fun mode). You should not hear the noise if these conditions are met. The sound itself is the ABS pulsing the brake caliper rapidly which is how ABS brakes work. It is a very smart system Broncos have for complete traction control when you need it. You can turn off traction control by pressing the traction control button once, and the car will still try to correct itself back to straight using from brakes independently. Holding the button, will remove it all, ESC and traction control. Trail turn assist using the same mechanism but works to do something different (off topic).

I’m hearing the exact same noise from video and I live in Florida it’s only when turning left. So you don’t have the issue when not on snow or ice? I do have a small lift and 35s so I’m thinking maybe rubbing?

If its making that sound on dry pavement, that could be an issue if it is trying to use ESC when it should not. Is the sound coming from up underneath the top side of the brake pedal assembly (inside the cab) or from outside the vehicle? See any areas where the tires rubbed on the crash bars or tires itself? Was the computer recalibrated to correct the speedometer for the increase in tire size? If not, the computer could be confused on the wheel speed it expects vs. vehicle actual speed.

The computer was not recalibrated. The issue only occurs when turning hard left like u turns. It doesn’t look like it rubs on anything when looking from outside of vehicle with wheel fully turned left. Maybe a computer issue then?

Gotcha. I bet that is the issue. It could be a data feedback decrepancy within the computer and wheel speed sensors. The dealer can do this or if you are comfortable doing it, many people have done it using Ford's forscan. Its a software you buy a license which is inexpensive. There are plenty of videos online of how to do it. I have this OBD2 linkEX adapter I use on my laptop. I just like this particular adapter. I'd get this corrected sooner than later so its not using ESC when it shouldn't be. I think that will fix it for you!

I bought it with the lift and tires from the dealer so definitely will be reaching out to them to have it done since they never did originally. Thanks so much for the help!
