Brake Shudder

[DanCoon]

"Break shutter" has a vastly different meaning than "brake shudder". OP might want to revise the title because some members might not read or respond to the thread because of it.

Ah yes, indeed. I shall revise the title before my post gets highjacked by the grammar police.

Honestly I was thinking that something in one of the cooling system shutters was broken Until I read the thread.

Ah, that did not occur to me - makes sense. I just assumed it was misspelled and translated it.

I have never seen any signs of rust on mine....but then again I live down the street from hell.

I live down the street from you. I resemble that comment. ?

Anyway. My rotors turn orange when I wash the car. I'm using softened water, maybe that accelerates the process. But they clean up when I remember to do an intentional hard brake.

Here are some broken shutters:

I believe these are the brakeded shuttersedd that the OP meant. Thank You for the service of claryifyeeing

Advice from most EV drivers is to do a couple “emergency stops” a couple times a week to keep the rust off the rotors. I’d try that a few times THEN see if you still have the shutter. Gotta knock the cobwebs off them before you can really judge it.
On the other hand, someone on here has already had their brakes stick and weld themselves together. So if they aren’t working right, best have them checked sooner rather than later.

Hey thanks, worked like a charm.

I have had same shudder at harder stops. Like a warped rotor since delivery. Doesn't do it all the time though. So it makes me think it is the ABS trying to pulse. A warped rotor in my experience causes a shudder all the time at high speed stops.

It's a known problem

Thanks. I have another thread on here somewhere explaining my ordeal with this TSB. It took my local Ford service department 2 tries to fix it and so far its been fine. I'm about 1000 miles into the second repair attempt.

I'm not sure if this is a "breaking in" issue, but I've noticed that when the break pads are engaged I get some pretty significant shutter. I rarely need to do a hard stop, but when the time has come it is something I've noticed. Anyone else experiencing this, or have any advice other than going to the dealer?

I've had shudder since delivery, must have been various joy rides before I took delivery a year ago, had several hundred miles on it before it reached me.

So I know what warped brake rotors feel like and took it to two different dealers on three occasions past year. TSB about pads and brake issues in hand, all said the brakes were fine couldn't recreate problem described.

Finally had time to take a shop foreman out with me in the car, he drove. Got it up to 50 mph, and had him come to an aggressive stop so pads and rotors would engage. He felt the shudder immediately, confirmed it was warped rotors. Going in next week to have rotors turned.

With the regenerative braking, a slow controlled stop rarely caused the shudder. I believe the service folks did not understand this, not did I, until more recently. I was baffled because rotors don't cause shudder due to warping only occasionally, it is more persistent. Then I read here how the braking is regenerative and caliper/pad/rotors.

Only thing now is they aren't certain if it will be covered under warranty. Hope repeated prior visits for the same issue is enough to keep it as warranty.

The rotors only warp when you overheat them when cold. Turning them removes mass from the rotor which only causes this to happen easier.

They're supposed to replace the pads and resurface the rotors.

I have brought the pads issue TSB with me the last three visits. Until a shop foreman drove the vehicle, all said there was nothing wrong. Foreman confirmed rotors were warped. They turned them, I know this removes material, not my favorite solution. Rotor replacement would have been a Golden Rule move on Ford's part, but I don't believe in fairy tales.

Brakes smoothly now, not grabbing the last foot or two of coming to a stop, no more groaning sound from brakes, and tell-tale warped rotor shudder is gone.

Again, vehicle was like this from delivery. Several hundred miles joy ridden before it got to me, pre ordered, shouldn't have been much more than the 18 miles the contract indicated. Since I was a very early delivery, getting help has been a challenge. Dealer Service had little experience with the Mach E. This forum has been immensely helpful as I have tried to figure things out.

I have also brought this to my dealers attention (TSB, etc) and had no luck.

I even took a recording of a nice clunking sounds coming from one of the rear brakes, which they agreed was odd, but apparently could not reproduce. (Which is true since I emergency stopped a few times to get it to go away...)

I figure I'll try again sometime soon and demand they try some harder breaking at higher speeds to hopefully feel the studder. It can be very annoying.

Hi there! Can you send us a message with your VIN and Ford dealership name? I’ll look into this on my end. Thanks!

You don't need to hard brake, just shift into neutral and apply pressure to the brake peddle. My Mach-E still does this, but I'm tired of leaving the thing at the dealership all day so I just live with it since it's improved a bit since they did the back rotors only.
