Component: Brake Booster/Master cylinder Available for inspection: yes Safety: Hissing sounds from brakes; have difficultly stopping; either the brake pedals become extremely hard and difficult to press down or soft that there is not enough pressure to stop.

Brakes are hard to push and they squeal, This is after several repairs. I have had front and rear pads and rotors replaced, replaced the power brake booster. Also I bought this car new and every time I am applying the brakes and turning the steering wheel to the left something underneath hits on the break and you can hear it and feel it.

When I attempt to brake, the brake is very stiff and hard to compress. It slows at a much slower rate than normal. Even when forcefully slamming on brakes it does not always engage. This has almost caused several accidents as I cannot brake normally. This is a safety issue for both me and other drivers on the road. It has not been inspected yet. I have done research and found many other internet complaints with the same issues, so I believe it it is the brake power booster.

- Poughquag, NY, USA

Brake booster has to be replaced which was being covered up until 2020 the mechanic told me so I liked to know why it's not covered now. I bought the vehicle in late December of,2020 so I wouldn't have known and I got it from a dealership. The brakes don't work because of this known problem. So I have a $800 repair bill I'm hoping to get taken care like it should have when I bought it. Thanks for your time and help!

Braking was an issue so got new brake pads and rotors per mechanic rec. Braking continued to be a problem and after having another driver verify the brake pedal, took it into the mechanics again. They said it was due to the brake booster failure - leak. Which is why I couldn't really press down on the brake pedal and losing the ability to securely stop - even with new pads and rotors on all 4 wheels. Car is at the mechanics since it's not safe to drive with its unpredictable braking. Called Ford customer service but said that there was nothing that they can do since the extended warranty 13N02 -?" Extended Warranty Coverage on Brake Booster -?" 2010-2013 Ford Edge & Lincoln MKX is not attached to VIN - they recommended in filing a complaint to see if it can get added and covered under this warranty. Given the date of when this car was purchased (12/20) and with COVID shut downs - it was difficult to address the brake problem - especially given work and everything was shut down. No warranty letters were sent informing me about this potential failure of a critical component in driving. Looks like there are many complaints from other owners experiencing brake failure and even a class action lawsuit support for Ford warrantying instead of recalling. There are also recalls of newer Edge and MKZ for brake booster issues. NHTSA, please help!

Our local mechanic advised us that the power brake booster was inoperable and that the vehicle was unsafe to drive. He advised us to bring the vehicle to Ford for repair. He also advised us that the booster has a known defect and Ford had extended a warranty to ten years for this part. We were never notified by Ford that there was a known problem with diaphragm in the power brake booster. This was confirmed by the local Ford Dealer. The vehicle is schedule to be repaired at the Ford.dealer but we cannot bring the vehicle in for another2 weeks. The estimate just to repair this part is.$ $850 and does not include any other potential damage to the brake system. According to the local Ford dealer and the original dealership they advised me that the extended warranty has expired for the brake booster and that Ford will not approve extending that warranty. I also called Ford customer service asking if they would be responsible for this repair since this was a known defect on this vehicle. This defect is definitely a safety issue but Ford is refusing to approve the repair. They are claiming that they voluntarily extended their warranty for 10 years and would have made a repair under the warranty if there was an issue with the braking system during that time period. I replied that since they never advised anyone of this defect we were disadvantaged to take actions to trade in or sell the vehicle. During the covid lock down this vehicle was hardly used and if it was driven it probably would have required a repair while under this secret warranty. The vehicle only has 50,000 miles on it, Ford has issued a case# cas33813024p7f6v3 on this matter but will not cover the repair The vehicle has been taken off the road and will have to be towed to the Ford Dealership to avoid an accident. It is completely not roadworthy.
