Abs engaged on snowy road. Now, brake pedal is extremely soft/spongy. . . Does not engage until pedal is fully depressed. County road. Straight-line stop. Replaced brake master cylinder and performed factory pressure/service bleed. Cause is certain to be the historically faulty abs hcu/control module.

The brakes do not function properly. The pedal feel is spongy and the pedal travel is excessive (3-4") before the brakes start to slow the vehicle down. Brakes were fully bled to ensure old fluid with too much moisture in it wasn't the problem. This action didn't fix the problem. Just had a Ford dealer replace the master cylinder--that did not correct the problem. After conducting a web search and talking with the dealer more, apparently the problem is a valve stuck in the open position on the abs system's hydraulic control unit. This appears to be a bit of a common problem with the fusion, Mkz and milan vehicles over numerous years. There also appears to be an updated part number for the hydraulic control unit. This condition is a safety hazard as the brakes do not properly slow the vehicle down when the brakes are applied.

Gentlemen, I own a 2007 Lincoln Mkz with 68,750 miles on it. I put a new master brake cylinder on it on August 16, 2015. The master cylinder was replaced because my brakes were periodically going �soft� after hitting rough patches on a road, striking wet, uneven manhole covers, or hitting slippery conditions which activated the abs system. Since that August installation of a new oem master brake cylinder I have had three more instances where the brakes have gone mushy after various attempts to make a quick stop. I've come to understand the likely defective part is the hydraulic motor control common to the cars under investigation as well as all others utilizing this same part. My point is that it is not just the 2007-2009 Ford fusion or the Mercury milan (which you are investigating) that has these suspected defective brake conditions. My 2007 Lincoln Mkz (and any other Ford, Mercury, or Lincoln automobiles which use this car's same braking system) has this same unsafe design. My latest incident occurred last week when a deer ran out in front of my car on a snowy road. I slammed on the brakes and avoided him. The abs kicked in and brakes have became mushy immediately thereafter. After taking my car in for repairs to the soft brakes, the brakes have not been returned to �normal�. I'm returning to the garage for a �fix� again. The soft brakes cause the car to take extraordinarily above normal distances to stop. I strongly encourage you to review the 2007 Lincoln Mkz for similar defects to that of the Mercury milan and Ford fusion. Although you are reporting no deaths currently as a result of these conditions to the Mkz, one / many are imminent. 475,000 cars all potentially with this same brake design are unsafe. One we know for sure that is certainly unsafe is the 2007 Lincoln Mkz.

The contact owns a 2010 Lincoln Mkz. The contact stated that while driving at 35 mph, the brake pedal was depressed and it felt stiff causing the vehicle to fail to decelerate. The contact also mentioned there was a hissing noise emitting from behind the brake pedal. The failure recurred multiple times. The vehicle was taken to a both a dealer and an independent mechanic where it was diagnosed both times that the power brake booster had failed and needed to be replaced. They also stated that the master cylinder also needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and informed that the VIN was not included in a manufacturers recall related to the failure. The approximate failure mileage was 115,000.

I was driving on sr 441 when a vehicle in front of me struck the median. I hit the brake pedal and the brakes did not respond. The vehicle was taken to al packer Ford (towed). The dealer replaced the master cylinder. On or about April 15, my son as operating the same vehicle when he needed to stop quickly. My son hit the brakes and they did not respond. No collision occurred at this time.

In a stopping situation today I heard a loud pop and then lost all brake pressure. I took the vehicle to a local repair shop and they found a rubber flex hose right off the master cylinder had blown out. This is in an area that is not very easy to get to nor is it near the bottom where salt and road debris can get to. My vehicle is out of warranty by 2,391 miles. I called the Ford Lincoln Mercury hotline and they said I was out of warranty and there was no recalls on this situation. I could have been in a bad accident or hit a child it was very scary. This should be investigated due to the nature of losing brakes is not safe. Hopefully this does not happen to anyone where there is an injury. This should be checked for a possible recall. Thank you in advance.
