Brake Noise – Front Grunting / Grinding on Ford Flex

Defective anchor brackets for the front calipers can cause abnormal brake rotor and pad wear concurrently. Noise can be heard while braking, a grunting or grinding from the front. The caliper anchor brackets should be replaced with revised parts, and also replace the rotors and brake pads.

Front brakes sound like metal on metal when I need t brake hard. Dealer inspected brakes 3 different times and says things look good. It's not good as, each time they have said it is due to the humidity in South Texas. That is BS! Ford needs to step up and fix the problem. My Flex has been documented 3 different times over the life of the vehicle and it now has 57300 miles.
Brakes locking....feels like the calipers are sticking and not releasing the pads...high pitched whistling that starts before the pads stick. This stops when I push the brake pedal. The rims are extremely hot after driving. Second trip to the dealer..

Pulsating breaks issue started at around 45K. After replacing tires pulsating went away, couple months later started noticing burning smell after long drives, break pads appeared worn out therefore got replaced. Couple more months later, got stranded 1hr away from home with car full of kids and home pets, saved by a stranger who took us to the nearby dealer to take care of the SMOKING LR wheel. Reason - LR outboard pad siezed in caliper, warped rotors. Dealer resurfaced rotor, cross send rear break pads, reassembled and lubed slides. Fix worked for about 12 months. Then RR wheel started to smell, replaced rotors and pins. 1 months later LR wheel burning smell AGAIN! Took it in again, now need to replace both calipers. No thank you. Seems like it should be recalled. But I don't care anymore, because I'm getting rid of the car.
I really notice this when leaving a parking garage and going around a downsloped corner.

I have a grinding noise when I apply my brakes. It has the metal on metal sound that have heard on other cars if the rotors are being scraped. I have a 2010 Eco Boost 6 cylinder that I bought 2 months ago. I took it to my ford dealer and was told that "rust" builds up on the brake pads during damp cold nights or hot days and once the rust is worn off it will not do it. It is true it only happens after the car has set over-night but the rust story did not strike me as true so I came online to see if anyone else had this problem.

Front grinding noise. Have gone to mechanic multiple times. Can't find issue. Have replaced breaks, pads, rotors and less then year later replaced again! Then couple months after my right rear caliber stuck and destroyed rotor, had to replace. So over the breaking issues with this vehicle! Why won't Ford fix problem. Disheartened to see so many others with this issue... Wishing I never bought it and may be time for a new vehicle.
I have had my flex for only 2 years and have been taken this in to the dealership for the whole time. They have replaced calibers, rotors, and pads on front left, and both rear wheels. The noise still persist. I have gotten to the point where I have asked Ford to take this vehicle back and I am working on returning or getting something new. The dealership cannot seem to find the issue and they continue to troubleshoot without success. The Service department has the same idea I did as far as turning it in. Any ideas would be helpful as I really like my Flex and hate to get rid of it because of something like this.

Front break metal on metal grinding noise. Replaced breaks and pads, stopped noise for a few months. Been to dealer 3 times and each time they say they don't hear it and nothing looks wrong.

I love my Flex, but I cannot drive it down a steep grade without a grinding/squealing sound that I find completely frightening. First dealer said it was due to glazing, eventually they replaced brakes but it still happens. I don't feel like I can slow down as much as necessary when coming down the Grapevine. I wish I could just buy new sturdier brakes. First noticed right after purchase and has continued.

I replaced the right rear caliper, both rear rotors and all the pads on the vehicle in late December, early January. Now there is front grinding noise and a possible caliper sticking again but this time on the drivers rear of the vehicle. This has been a known problem since the 2009 model and the fix is supposedly new rotors, pads and brackets to take care of the problem. Here it is 6 months later and I have to replace all the breaks again. Why hasn't this been recalled?

SAme prblem. Dealer performed the TSB
2009 Ford Flex7,200
Same as all the other people. Several TSB's applied - still has the same issue on the Right front brakes. Now have in addition a Vibration under the Drivers Floor pan after the brakes are released (soft, or medium, or hard braking - does not matter).

Really bad grinding sound from front brakes when applied heavily.
Had a 2009 Ford Flex with the same issue. Ford replaced free of charge under a 'voluntary' recall program. The 2009 was totaled in an accident and we replaced with a 2010. Same issue. Taking into Ford this week to have it replaced. Should be no charge.
