Heavy right foot = traction control using rear brake to keep the rear tires from spinning.

 

Must be a REAL heavy foot!

 

I thought so too with my 2010 Premium. Now with my 2013 SC, the traction control is always working. The back tires just spin so easily.

 

I have read elsewhere that the EBD system and to a lesser extent the DSC system have a bit of "anti-dive" programmed into them, such that under moderate to heavy braking much more braking force than on 'normal' cars is directed to the rear brakes. However I couldn't find any mention of this in the Workshop Manual. Combine lots of this type of driving (fairly heavy on the brakes) with the soft as butter OEM brake pads could explain the rear pads wearing out so fast. Conversely, under really heavy braking, at or near the threshold of ABS activating, the EBD system sends up to 90% of the braking force to the front brakes.

 

I was told a while back by my Jag Tech buddy, that while I was reading here that Rear brakes wore faster than the fronts, he said it was because the brake biasing under normal stopping conditions is favored to the rears to help alleviate nose dive while stopping...Makes sense

 

LoL Maybe... Would be even worse with torque vectoring.

 

From my time driving the XF, this comment validates some initial reactions. I noticed the nose seems to stay level during braking. Diversion to the rear brakes seems a plausible explanation to this sensation.

 

That seems to make sense, as I had to replace the brakes 4 months ago, on my wife's 24,000 mile (at the time) '09 XF. I could see that the rears were SIGNIFICANTLY more worn than the fronts, but I replaced all 4 rotors and pairs of pads.


I went with Beck Arnley replacement rotors and Powerstop ceramic pads. So far, so good. Cost for all the parts, from Rock Auto, including shipping, was just under $400.
