rear brakes on my 2010 fusion hybrid

[mmtphoto]

our 2010 fusion hybrid now has 119,000 miles we bought it in 2017 with about 90,000 miles.  shortly after buying it in '17 i replaced the rear brakes as they were low and made some noise...fast forward to this week, my wife who usually drive it said she started to hear the rears making noise again.  i pulled the wheels and sure enough, the outer pad on the driver side was down to the metal at the top of the pad and it left a small swipe on the rotor.  i removed the rotors and replaced them with new along with new pads.  i cleaned up the brackets, installed new anti-rattle clips and tried to get the pads into the slots but they were so tight i ended up grinding the ears some on all the pads so the fit would not be so tight.  even after doing this, the driver side still seems to have some drag, and the pistons were turned back in as far as i could get them. 

anyone have any idea why this is so?-i'm a little surprised that the rears seem to go so fast on these, the fronts still have probably 40-50% material and the rotors are pristine.  I have no way of knowing if they are original pads up front, but have seen others on here over the years claim to get 140-150 thousand miles on a set of fronts.  does anyone have any theories or history of how often rear pads get replaced on this particular model?  thanks in advance.

Looks like the caliper slider pins are seized. Need to lubricate those once a year.

The rear brakes get partially applied every time you hit the brake pedal, they are not involved in the regen process of charging the battery when you step on the brake, which is all done with the front brakes.  Hence if you only make gentle stops, the front pads will last forever.  But factor in that the rear brakes are set up to only do about 30% of the braking, even on a normal non-hybrid car, so the FFH rear brakes should still last as long as on a non hybrid. 

 

You have motivated me to simply do new pads on my 2010 FFH rear, since I noticed last time the original rear pads are slightly over half worn.  And I will also lube the pins.  Anyone want to buy a pristine 2010 FFH?  No accidents, no issues, 154K miles.   Still gets 40 mpg, and the nickel metal hydride high voltage batteries were still running on hybrid Excape Taxi's in California at 300K miles.  My Wife died recently and I only need the 2015 C-Max now. 

 

Here's how to think about the life of the rechargeable high voltage battery (HVB).  If you had a rechargeable flashlight, that was computer controlled to never be over-charged or undercharged by controlling the in and out current whenever it was being used, that flashlight battery would last for decades, in that computer controlled environment.  Because that's what happens in an FFH, the computer babies the HVB.  Over charging and under charging is the thing that eventually wears out any rechargeable battery which never happens on an FFH.  That's why Ford doesn't even stock replacement HVB's.

first thing i check is always the caliper slider pins to make certain they are free to move.  I removed the caliper bracket and cleaned it up with a bench grinder wire brush, seems to be free now. 

 

Sorry to learn of your loss Vanore Tn

Thanks to all.  I really miss my Wife, she did all the bills and taxes and was the Club womens golf champion not so long ago.  She had many good years left, stolen by cancer.  You often don't realize what you have until it's gone. ?  The FFH sold the first day on Craigslist.  $5K.
