TSB 21-2206 Vibration/Pulsation From Brakes - Brake Pad Material Stuck To Rotor

[generaltso]

Sooooo what is the resolution for this? Everytime it rains, or you wash your car....don't park in your garage afterwards?

The resolution is detailed in the TSB.

Just got mine back this evening. Three weeks to the day from having it towed to the dealership. The rotors were finally available last week for the dealership to order.

The TSB refers to front brake pads, etc. Any reason to think this doesn't apply equally to the brake pads and rotors on the rear wheels? Probably a dumb question but I'm asking because my Mach-E has this issue on the left rear wheel. This started last night after leaving my Mach-E in an airport parking lot for a week (when I drove to the airport it was pouring rain...consistent with other descriptions of this problem). After reading these posts, I looked at the rotor on my Mach-E and saw and could feel some material on the rotor which could definitely be causing the sound. The driver's side rear wheel also had some of this material on it. When I first left the airport, both rear wheels sounded like they were making this sound. But this morning, it was only the rear passenger wheel making noise. I have an appointment at the dealership tomorrow. I really hope I don't have to wait long for the parts....fingers crossed.

Isn’t this situation dangerous, part of the pad sticking to the rotors can’t be a good thing when stopping hard

Thank you for the TSB.
I was parked at an incline with the parking brake on. I put the car in drive and started driving, the parking brake auto-released (as it's designed to) but it made a very loud clank! As I got down the road a block I heard *thud thud thud thud* in cadence with the wheel (I thought I had a flat tire). After inspecting the tires I drove and realized it made that sound as I was braking. It only made the sound when braking under 30 MPH. I live close the my dealership so went there straight away. (I made an appointment for Tuesday since they couldn't look at it). I drove home without incident, and the *thud* was getting softer, but still disconcerting. It sound like this is the same issue, though it sound like it's coming from my rear passenger side tire. I'm bringing this TSB to the dealer for my appointment.

When I backed into my parking spot I got this error on top of it. (see pic).

I've also noticed when I park on an incline it's very "creeky" when settling in to it's spot.

I realize this thread has sat for a few weeks, but just wondering if this applies to a GT? Been scouring the forums and the internet and can't find a definitive answer - just want to be on the look out for it if need be.

So it would seem this happened to me this morning leaving for work. Drove my Mach-E last Friday in the rain, parked in the garage over the weekend. Went to leave this am and it was a pretty jarring release of the brakes. Then I start hearing the "clunk clunk" as the rear wheels turn. Took a quick video to get the sound to play for service folks. Did some hard braking and the noise stopped after some nasty sounding grinding, but at least there's no more clunking as a drive.

Now to try and actually get ahold of a service adviser at my dealership...

Well let's see how long this takes, dropped the car off on Monday, December 13th they ordered parts that day

The work should take less than an hour for any competent tech. I called ahead of time and they ordered the parts before I arrived.

So that is what that sound was? Same scenario, washed Mach E and washed wheels and shiny red calipers, parked in garage. Next day I drove, the brakes were locked, nudged in reverse then broke free. Heard scraping noise from right rear, stopped and investigated. I didn't see anything amiss, used volume knob on screen to increase radio volume = problem solved.

No pulsating at this time but I will add to the list of things to address at 10,000-mile service. Not doing pano and windshield recall after reading other thread.

I think they need to expand to the rear brakes too from what I am reading. Ok Ford!

I did too made my appointment in November, however the dealer said they needed to inspect.

I had the issue after driving in the rain and parking over night. In the morning while attempting to reverse I hears a loud grinding sound. Upon moving forward the rear wheels thumped as if I was driving on square tires. Thumping increased with speed increase. I pulled over. Did a basic visual inspection. Noticed the driver side rear wheel rotor covered in what looked like rust. I did an Internet deserve and discovered the brake pad issue everyone is referring. I continued to drive cautiously and over time the thumping sound quieted and eventually disappeared. I took it to the dealer along with the service bulletin. Unfortunately for me the tech saw the bulletin was for the front wheels and only inspected the front wheels. Ugh!!!! So no fault was found and no further work or inspection of the rear was done. Of course no fault was found because the tech inspected the wrong wheels. But yes there is an issue with the rear. I have photos. So even though the rotors are now shinny because braking has cleaned them, the issue remain. Since I have to return the vehicle for the windshield and glass roof recalls the dealer will inspect the rear wheels at that time. I am fully expecting they will replace the brake pads with the ones that do not have the center V groove.

I was fortunate that mine ultimately took my word for it over the phone and ordered the parts in advance.

It worked out, picked up the car today. New rotors and pads took a few miles to wear in.

The rear brakes may not have the center groove. It's normal for brake rotors to have some surface rust on them if the car sits overnight. On an EV like the Mach E you don't use the brakes much so they are even more likely to have rust after all rotors are raw metal any water or especially salt and water will rust them quickley. Also on a EV it may take a fair amount or breaking to remove the surface rust and get them to smooth out.

This may not actually be a problem. but I agree worth having them inspect when you are having other work done.
