Rotors warping 3rd time in 7 months.

[TheSteelRider]

After a couple of weeks I came back to this thread expecting to hear more about the brakes being Santa's helper and I'm shocked, surprised, and disappointed that they no longer are.

Dealer went for the whole brake job option. 6mm left on pads, suggested replacing all 4 wheels pads. Turning all 4 rotors. I'm just so excited to pay for this repair that really should not have been necessary. I don't have the $ amount for the repair yet. I'm even more excited to see how long it goes without warped rotors, I'm hopeful it will not be an issue again. Still, not going to hold my breath.

The automatic electric parking brakes don’t help us either. Forces the pads against the rotors then lets them sit and bond together causing the pad material to stick to the rotor. Especially if you put the car away wet. Thus the popping a lot of get when we first start driving. That pad material and corrosion can cause uneven wear after that. I love the braking on the car. But I do wish I could pick to use the parking brake or not.

I'm not totally sure the new auto-squeeze isn't hurting it as well. When I got my car if I tossed it in park and took my foot off the brake the car bounced around a good 3 to 4 inches. Sometimes I could time it right to hit my kid with the door as she got out (not on purpose but it happend a few times). Now it's got the tiny hold which helps tremendously, unless you're coming off a hard braking session and they're hot. Then it's helping hold the pad heat some.

My 4 wheel brake job (turning rotors and new brake pads) didn't make it past 2,000 miles before showing signs of warped rotors again. Now another 1,000 miles and the shaking steering wheel while braking hard enough to engage pads/rotors is unmistakable and extreme. Anyone have luck getting a dealer to get accommodation from Ford Mfg? Any aftermarket solutions I can have dealer install or would I need to go elsewhere?

As a tech, I've done a lot of brake jobs in the past. Think you need to find what is different from your conditions to the thousands of other Mach-E's out there. Is it environmental, driving habits, or something with your specific chassis. Maybe all of them together. Sounds like you would be a good engineering study for Ford.
I have seen disc that take a bit to break in and go through a surface hardness variation. But allowed to run with light braking they wear in and it goes away. I experienced it around 2500 miles, but it's fine ever since (35,000 now). Are you driving dirt roads or a lot of potholes that hold water? Pressure washer? Steep hills? Daily use or does it sit several days at a time. Average trip milage? All plays into it. But they will still blame driving habit as the number one cause. I worked for 5 dealers and saw it often.
Have you determined if the disc is warped or has corrosion spots.

I drive in Engaged Mode. In town, surface streets and freeway. I don't drive it hard, no excessive hard braking, and I don't get it wet after driving downhill for an hour. None of the typical "user error" conditions exist for my use of the brakes. It's flat out a design or materials issue. Brake pads have been the correct ones from day one, the TSB for channeled pads didn't apply to my car.

Dealer has ordered 4 new rotors to put on the car at my expense for the parts. They will waive the labor since it was in so recently for a 4 wheel brake job and new pads.

I have been dealing with it since last January so im just used to the bad rotors now... however one pedal drive shakes when stopping in the early morning... it goes away after a few stops but not sure what thats about...

Spot rust from hot rotor and moisture is likely. I don't know where you are climate wise, but residual moisture between the pad and rotor like running thru a puddle before you park will do it.

You saying that’s what causes the one pedal drive to shake when it’s been sitting over night?

One Pedal? Describe what your shake is please. Is the car like surging?

If you’re going above 50 miles an hour whenever the car‘s been sitting for a while and you just let take your foot off the pedal completely and let the engine slow it down. The steering wheel will shake really fast left and right about an inch each direction. I know my rotors are bad so I didn’t know if the one pedal drive somehow activated the rotors or the brakes to slow down or not. If that’s the case then my rotor is being fixed. We’ll solve this issue however I was told that one pill driver does not use the brakes or the rotors so then then I was like well what causes the one power drive to shake if it’s not the rotors or the brakes. Sometimes a slow speeds are definitely feels like somethings like catching every few inches like. As this is my first electric car I’m really not sure how that’s supposed to sound.

If you are driving at 50mph on level ground and take your foot off of the accelerator (regardless of 1P setting), the brake pads should not be engaging. Any shaking / shimmying at that point suggests a different issue.

That’s what I’m thinking, but the feel like I’m being gaslit by the Ford dealerships

Turn off 1P and see if the same thing happens at 50mph when releasing acc. pedal. If it does, then maybe something in suspension or tires. If it only happens in 1P, then maybe something with drivetrain (motor / diff).
