Brake Master Cylinder Problems of Lincoln MKX

When using the brakes the pedal goes all the way to the floor and stops slowly. This is done while driving regardless what speed. The brakes would return and go back out randomly. I have the brakes go out on highway and city street as well as in park or in gear. Brake booster recall was done and the problem persisted. Returned to Lincoln and diagnostic was done stating needing to replace brake master cylinder and hydronic control. The hydronic control needs to be recalled. The price can go out without warning and cause vehicle not to stop.

I was driving and brakes went to floor no pedal at all. Before this happened the pedal was stiff and hard to push. There are no brake leaks master cylinder is full the brake pads are fine. I was wondering if it had a brake booster issue.

Brake pedal very soft, goes to floor making it difficult to stop. After pumping brake a couple of times braking possible but still not right also a hissing sound can be heard. This happens when trying to stop on either city streets or highway. Example when stopping for a stop sign or signal. First repair shop I took it to checked my brakes and said they were fine. After still experiencing the problem I took it another repair facility and they were able to fix the problem by replacing the master cylinder and brake booster. Car now stops ok. This was at 46703 miles.

Tl-the contact owns a 2008 Lincoln Mkx. The contact stated that while driving approximately 30 mph and depressing the brakes, but the brake pedal would not release. The vehicle was able to slow down, but the contact used extreme force to push down on the brake pedal. The vehicle was taken to the dealer for diagnosis. The dealer advised him that the master cylinder was leaking which caused the rubber to harden on the brake pedal. The vehicle was repaired for the booster and master cylinder for the front brakes. The manufacturer was contacted and they offered no assistance. The failure mileage was approximately 71,000 and the current mileage was 72,500. The VIN was unavailable. Tb.

While our 2007 Lincoln Mkx was standing still, pressure was applied to the brake pedal and it went to the floor. I tried it several times over the next few days with the same result. Took it into the dealer, dealer said it was normal. I objected to that comment. On further investigation by the dealer, they said it was the master cylinder. They did replace the master cylinder. I got into the vehicle, pressed on the brake pedal, thought it felt funny, complained again to the dealer. They said they would give me a test drive with the same type of vehicle. Before that happened, the mechanic came out, got in my vehicle, pushed down on the brake pedal, which again went to the floor. His statement was huh?, must be in the vacuum system. That system is in the process of being replaced. Will keep everyone posted in the next few days.
