I hate asking questions but


Recommended Posts

As per Ford's specifications for the Edge & MKX on media.ford website, the FWD "regular" Edge has smaller front brake swept area (63.1 sq. in), whereas the Edge AWD, Edge Sport (FWD & AWD) and MKX (FWD & AWD) all have 69.79 sq. in. of brake swept area. Different swept area would mean different sized rotors. Rear, they all have the same swept area, 70.12 sq. in.

 

For Calipers & Pads, there does not seem to be any difference as on Fordparts.com there is no differentiation between different models for Calipers & Pads except vehicle made before 9/20/2010.

Perhaps things are changing for the 2014 model year. That spec sheet just shows all FWD as being 63.1 and all AWD as being 69.79 for the front. The rears are the same at 70.12.

 

There has to be a difference somewhere to get the different sweep area numbers. May not be bigger calipers but bigger brake pads which fit the same calipers?

 

RockAuto is showing the same Motorcraft/Ford part numbers as being the same for both the 3.5 and 3.7 engines, and have no separate category for FWD and AWD regarding the brake parts using a 2011 as the year.

 

I really don't know where the different sweep numbers come from, but it looks like the brake components (replacement) are all the same regardless of model, engine, or drive type.

Sometimes they list the Edge Sport in a different spec sheet, and in that case, the spec sheet for the Edge (non sport) would only show difference for AWD/FWD.

 

For brake pads and calipers, Ford did this before in the 96-99 Taurus & Taurus SHO. Both had the same brake pads & calipers, but the Taurus SHO had larger Discs & with longer/larger "caliper brackets" that allowed the same calipers to be mounted farther from the hub to make space for the larger Discs.
