Car fell apart in my garage?

[jwhamlin244]

UPDATE 11/17: Took the car into the dealer. It was in fact the break pad material breaking issue TSB 21-2206. Dealer ordered new Rotors, pads, and bolts. They should be in by the end of the week. I'll probably get them installed after Thanksgiving.

Hey all,
so pulling out of my garage today, it seems that in reverse, the brakes didn’t fully disengage? I could feel resistance so I started recording. Backing up there is a loud bang and the car starts moving. This is the second time this has happened.
After this time, now there is a rhythmic clacking noise as I’m driving. Anyone else have a similar experience? Is this that break debris issue that is known? Making an appt at the dealer but can’t get in for a week.

For sure get that to the dealer. No denying something is wrong there. Whats wrong? Dont have a clue. Good luck. Keep us posted. ?

It does sound like the brake pad sticking issue, but your car did not "fall apart"

I'm not suggesting this is your problem or your only problem, but by chance had you parked your car after it rained or you washed it?

I've noticed mine doing something similar after letting it sit in my garage after a wash. You might find this thread interesting- https://www.macheforum.com/site/thr...g-sound-and-ford-roadside-on-speed-dial.4730/

You saying I exaggerated?! Maybe a little but the jerk, bang and then rattle sure makes me think something fell apart.

I live in Seattle, it’s always parked after a rain storm..

That other thread is exactly my issue, thanks for finding that for me. Next time I drive, I’ll intentionally use the brake to try and scrape off the rotor material. I have a dealer appointment on Tuesday and I think the car is safe to drive until then at least.

Your video definitely sounds like stuck brake pads to me.

Here's the TSB: https://www.macheforum.com/site/thr...rakes-brake-pad-material-stuck-to-rotor.8971/

Did your car sit for an extended period of time waiting for a chip? Under the right conditions that can set the brakes up to form rust. Once it takes hold it can get out of hand quickly, pads can bond to the rotor.

Rusting brake components can be especially troublesome on EVs as the brakes are not used often if you mostly use regen.''

With a car this new you should be able to get the dealer to admit you have a defect, not normal wear. This could lead to replacement of the pads, calipers, rotors, Ebrake components, etc. Not really a big deal on an old school mustang - but expensive and lots of crazy steps involved on the new Mach E. Don't let them charge you.

Stop using the parking brake in your perfectly flat garage?

I'm not saying that you shouldn't be able to, or that Ford shouldn't fix this, but if you know it's the parking brake just stop using it unless parking on an incline/decline.

I don't think I've used the parking brake once on my MME yet.

I get the same issue. But I don't think it is anything to much to worry about. It only happens after I wash the car and then park it up OR if I have been through rain and parked up. It's just the brake pads binding with the discs. Used to happen on my previous ICE cars in the same scenario.

This happens on all cars but I think it can be exaggerated on EV's. When it is wet or humid your brakes get wet. When you park with your Emergency/Parking brake set all that moisture causes rust and your brakes stick. This problem will happen on an EV more due to regenerative braking. In an EV you don't use your brakes as much so they don't get hot or operate to get rid of the moisture. If you start using your brakes more before you get home you can possible alleviate the problem.

Does the clunking noise change with speed? I've never heard brakes make that noise but loose lug nuts make that exact sound if it changes with speed.

The park brake doesn’t have to be on for the car to set it. You probably have brake hold on. Mine does this also not in a wet environment though not to this extent. Seems normal to me if you are in a wet environment. The thumping sound is the rusty spot on the rotor where the pads were. Apply the brakes at speed and it should go away. Internet mechanic but not certified.

Could be an issue with the parking pawl in the rear drive unit.

My car does the same thing every time after I wash it if I just put it back into the garage without driving it. I'm one of those that always use the parking brake, and I make sure I don't engage the parking brake after washing, but even then it still happens. The same rhythmic clunking noise too when driving which goes away after I use the brakes rolling down the hill out of my neighborhood. That clunking noise seems to come from the front so it has nothing to do with the parking brake. Seems to me the front pads are also getting fused to the rotors from rust.

What was equally annoying was my wheels having a coat of yellow dust from the rust after I cleaned and coated my wheels.

I read an article this morning on the 2022 MME I thought it mentiined that parking thing was changing in the new 22 model somehow. I need to find that. Grrrr.
