My 2009 MKZ makes a crunching / snap noise when you apply the brakes at low speed such as pulling into a parking space. Our car has 14K and has been to the dealer where they told me that " all MKZ do this...there is no solution". Yikes!! The Lincoln mechanic proceeded to show me using another customer's MKZ make the same noises in the parking lot while I stood there! He said they all thought that the brake rotors were rotating slightly on the wheel hubs before using up the small amount of slack designed around the wheel studs holes on the rotors
. I went home and pulled both front wheels and checked all bolts and brake items. The rotors are held in place on the hubs with two set screws so there is zero movement backwards and forwards on the wheel hubs. The noise happens with the wheels in all positions including turned and straight ahead. Anyone had the same issue and have a fix?
EDIT - My reply crossed in the mail with Mercury_66's.
Not sure if your Tech gave you a bad explanation, but this is one possibility: Some of our cars (MKZ, Fusion, Milan) exhibit a bit of slack/looseness in the brake pads/brake pad clips/springs.
This looseness can result in the brake pads shifting ever so slightly the first time you apply the brakes after shifting into Drive or reverse. Essentially, the first brake application each time results in the pads shifting forward or backward and making a noise. You will only hear it at low speed since it only happens the first time after changing direction (D to R or R to D).
It can sometimes be alleviated, at least temporarily, by having the offending parts re-lubricated. Also, some owners have found a longer term solution when their Dealer replaced the clips/springs.
Don't know for sure if this is what is causing your issue, but it is a possibility.
Let us know how you make out and good luck.
