This post will probably need to be edited as more information is gathered...
I've used a few different sources such as Mitchell 1 OnDemand5,
RockAuto.com,
FordParts.com, and
NAPAOnline.com. All of the part numbers mentioned below were taken strictly from
FordParts.com.
Unfortunately, it does look like there is some variation in brake systems across the MKS/Taurus lineup, but I'm wondering if it's just with the materials used as opposed to the dimensions even though the dimensions vary from one website to the next. It hasn't been by much, so I'm thinking it is just in error.
According to
FordParts.com, even though original equipment part numbers were different, they have all been reclassified under the same new part number for the front (1125) and the rear (2C026).
The breakdown:
2010 - 2012 Lincoln MKS and Ford TaurusFRONT ROTOR (through 7/27/2010 for 2011)
Motorcraft P/N: BRRF-18
FRONT ROTOR (from 7/28/2010 for 2011 through 2012)
Motorcraft P/N: BRRF-75
REAR ROTOR (through 9/12/2010 for 2011)
Motorcraft P/N: BRRF-48
REAR ROTOR (from 9/13/2010 for 2011 through 2012)
Motorcraft P/N: BRRF-70
2013 Lincoln MKS ONLY-2013 Taurus SHO information is not complete at this timeFRONT ROTOR (through 6/17/2012 for 2013)
Motorcraft P/N: BRRF-112
FRONT ROTOR (from 6/28/2012 for 2013)
Motorcraft P/N: BRRF-202
REAR ROTOR
Motorcraft P/N: BRRF-92
Again, even though there are differences in the original equipment part numbers,
FordParts.com lists a new part number that covers all of the bases including the 2013 MKS.
FRONT ROTOR: 1125
REAR ROTOR: 2C026
2013 Taurus information is not complete at this time.
