tergos Posted July 4, 2019 Report Share Posted July 4, 2019 2017 AWD Titanium with the 3.5 is the best car we have ever owned but the rear brake life is way less than expected at 23 months on the road. Rear pads worn out and rotors scored. Front rotors are smooth and 10mm is left on the pads. We drive carefully, no stop and go, about 70% highway and the car sees no winter salt. The dealer has no explanation for the difference and of course there is "No Warranty". We are anxious to avoid replacing the rears again so soon again. Could it be off spec or aggressive (semi-metallic?) pads on the rear which wore badly and were the reason for the scoring of the rotors. The front pads and/or rotors were possibly different materials? I have never found my rear brakes wearing out so quickly; usually the front wear out first. The tires are all worn the same with 9/32 tread depth remaining. I have retained the worn rotors and pads in case I need them to find the answer. We have found cases of similar mismatch of front to rear brake life on the internet but no real analysis of what caused it. We would appreciate any help to explain this.

fishx65 Posted July 6, 2019 Report Share Posted July 6, 2019 I don't think it's uncommon for today's vehicles to wear out rear brakes before fronts but 20,000 miles seems crazy. I changed out the fronts and rears on my 2011 at 60,000 and the rears were definitely way more worn then the fronts. I'm sure pure city driving and driving habits can play a big part in brake wear. Do you drive like Speed Racer and never leave the City??:):) 1 1 Quote Link to comment Share on other sites More sharing options...
paker Posted July 7, 2019 Report Share Posted July 7, 2019 Rear going before front is out of norm imo. I would suspect lack of lubrication of moving parts. Sticky caliper sliding pins, caliper piston not retracting fully, etc. Were both sides (driver and passenger) worn about the same? Were both pads (inner and outer) worn about the same? 1 Quote Link to comment Share on other sites More sharing options...
tergos Posted July 7, 2019 Author Report Share Posted July 7, 2019 We drive very defensively as previous vehicles we've owned getting 60k miles at least with fronts always worn more than rears Most of our mileage is on the highway and we use the cruise where possible which spaces us back up to 5 carlengths so no heavy braking except for the odd idiot drivers in the city Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted July 7, 2019 Report Share Posted July 7, 2019 Electronic Brake Distribution is the commonly given answer. So if your Edge sees more "action" the rears come into play more often. Also the rears on 2011+ serve as both brakes and parking brakes. 2007-10 had drum brake assemblies for the parking brakes. So there is more wear and tear for sure. But I think EBD is the most likely answer. Quote Link to comment Share on other sites More sharing options...
Bankz703 Posted July 12, 2019 Report Share Posted July 12, 2019 As far as combating the issue with how fast the pads wore out, I would definitley stick to the O.E. recomendation on Brake Pad material (Full Ceramic) but look for a higher premium pad so you can get more miles out of them.

Jhough Posted January 23 Report Share Posted January 23 My dealer service just told me my Ford Edge 2021 with only 14,000 miles of very easy driving, will need the rear brakes replaced. What's with that??? Quote Link to comment Share on other sites More sharing options...

What's with that??? Too bad you are likely out of your initial 3yr/36k miles warranty, I would say that is extremely early and indicative of a problem that would be covered, even though it is a wear item, there are exceptions. Did they explain why they needed replaced? Wear (down to 2-3mm), abnormal wear (one pad worn while all others are fine), contamination, delamination, caliper issue, or anything else? Was this found during a normal service visit (like an oil change with a 99 point inspection) or due to a complaint about brake issues? When I took my vehicles in for "TheWorks" oil changes they would measure the pads and mark them off on the inspection sheet as both a color (green, yellow, red) but a range in pad material left. I am pretty hard on brakes, I had around 96,000 miles on my 2019 when I replaced them. The rears were getting close to 3mm left, I suspect I could have gone another 10,000 miles easy, and the fronts had more than half remaining, but I replaced them all around anyways, easy cheap job and the weather was moderate and made it less of a choir to do. My rear pads compared to new, you can see one side was a bit more worn than the other, and at more of an angle, but still had a bit of pad left: Quote Link to comment Share on other sites More sharing options...
