I have this strange wear pattern on my. Rotors does anyone has the same problem

Please see the pictures and tell me if this is normal. Dealer said this is normal Is it? They say not to be worry about it because my car breaks with the engine. Most of the time

First 2 are rear rotors left and right

Second 2 are front rotors left and right

I have the same thing going on with my car. However I got 75K miles on the original pads and rotors. Front pads seem to have about 60% life left and rears have 40%. I will try some spirited braking and hope this goes away. I know I am bringing up a thread that is over an year old and wanted to see what other members are seeing!

My brakes look the same as the ones shown in Post #1, braking performance is still excellent and I use Mechanical brake once in a while with tranny in Neurtral. You've got a good dealer because my local dealer gave me a lot of BS about it and wanted me to change the pads and rotors for a lot of money

My dealership quoted me over 1000$CAD to change all four rotors and pads because pads were worn and rotors rusty on my 2013 C-Max with 35K km on the odometer!

 

I asked a mechanic friend to check it out. On the front, the inside face of the rotors were OK but the outside face showed a pattern similar to the photos in the post above. New pads and cleaning should do the trick.

 

In the back it appears that both sides are quite rusty as it seems they have hardly been used probably because of regen braking. In addition, one and possibly both caliper pistons are seized.

 

I do not drive much and I admit that I have not engaged in "friction" braking to any extent. Does anyone know whether Ford recommends procedures to alleviate the minimal use of such braking with hybrids? And also whether dealerships are told to be on the lookout for this problem when they do regular maintenance?

 

Thanks

Just took the car in for a list of concerns.   Getting close to the end of standard warranty ~33k miles.   One issue i stated was minor brake noise on the right rear in the morning while driving (no brakes applied).   This was really minor but thought I would put it down on the list to have it looked at.   They ended up resurfacing the rotors in the rear.  Said I had lots of pad left. 

I have 52,000 miles on my car now, but my rotors looked like the ones in the photo by the OP right after I drove the car off the lot and have only gotten worse.  My pad wear is minimal.  The brakes have occasionally been noisy while driving at low speed and now they can be grabby if I am braking a bit aggressively.  I too am concerned about the health of the calipers.  Since winter (salt application) is winding down up here, when I go to get my studded tires replaced with my summer tires, I am going to ask my mechanic to assess the overall health of the braking system.  This really is about my only complaint about the vehicle.

Some 30 years ago i worked for a company that made gas pumps.  One of the major national petroleum companies complained that our pumps would not hold calibration well enough to pass weights and measures checks.  All of our tests showed excellent calibration, right in the middle of the +/- allowable range.  Eventually we learned that it was their company's policy to set pump calibration right at the low calibration limit.  Then, if the calibration drifted just slightly lower, they would fail inspection.  

 

By setting calibration low they saved a fraction of a percent on every sale.  It's very little on a per-sale basis, but when you sell millions of gallons it adds up to a large amount of money.

 

That's long-winded way of saying that gas station operators have a built-in mechanism by which they can deliver less gas than they report and charge you for.

Great story!   It reminds me of the scheme in the movie "Office Space."

Unfortunately, the two times I have checked so far the pump has been about a gallon high vs. the car.  I don't consider a gallon discrepancy "slightly lower" or "fraction of a percent."  Also, I commonly purchase 2.5 gallons in a plastic gas can for other than vehicle use.  I have had this can for many years and the manufacturer molded a line in it at exactly 2.5 gallons.  I have not noticed a difference between 2.5 gallons registering on the pump and the fuel level being anything but touching the line on the can, which still makes me wonder how the C-Max can claim 1 gallon less used.

I believe I read in the manual that Ford recommends only allowing the auto shut-off on the pump to shut off twice when filling the tank.  I was trying to top off the tank (old habits) more than this, but will begin using Ford's recommendation and see if the next few fuel ups are closer to what the car claims as gas used.

Thanks for the story.

I have also noticed a discrepancy between the pump measured gallons vs. Trip 1 gallons.

During my second to last fuel, the pump measured 10.866 gallons where Trip 1 said 9.87 gallons.  This is a difference of 34.4 mpg vs. the 37.8 displayed mpg for the 373.8 miles traveled.

For my fuel up today, the pump measured 8.584 gallons and Trip 1 said 7.62 gallons.  This is a difference of 33.6 mpg vs. 37.9 mpg displayed on Trip 1 over 288.8 miles.

I would be hesitant to believe the pump, except New York State over-regulates everything.  You get to stare at the recent Bureau of Weights and Measures stamp right on the pump while fueling and also I happen to see the guy several times per year out measuring the tanks and certifying the pumps at different stations.  I even spoke with him a couple years ago.

Any ideas?  Has this been discussed in another post?

Thanks for the congratulations.  This is the first hybrid I have ever driven and the mileage achieved was both with myself and my wife driving at different times.  We are very surprised at the mileage we have achieved and that we were able to do this on our very first tank.  We hope to continue to be pleasantly surprised, but we are a bit apprehensive of our upcoming winter weather and the addition of snow tires.

I usually drive very conservatively, most recently trying to squeeze the mileage out of my diesel truck, but I do not consider myself a hyper miler (is that a word?).  I just like to try to keep the ratio of money saved vs. sent to big oil as much in my favor as possible.

First fill up tonight with 916.2 miles on the odometer.  Three weeks ago we left the dealership with 315 miles (using 315.9 for calculations) on the clock and a complimentary full tank.  After Ford's recommended two clicks on the pump handle, I had added 13.242 gallons, which gave us 45.34 miles per gallon and 600.3 miles from our first tank.  Our information screen displayed 45.9 mpg and we had to travel 18 or 19 miles beyond zero fuel remaining.  We wouldn't have done it without a full 3 gallons gas can in the back for peace of mind. 

Does anyone have any idea how accurate the odometer is in the C-max?  How many attempt to adjust for actual miles traveled vs. odometer?

"There are many posts and threads here about Consumer Reports and many of us have SERIOUS ISSUES with their :airquote:  unbiased reporting. Does CR sell bridges to nowhere as well? If you have time, go take sometime and scour the many threads and posts here...some are very funny."

It is actually because of the March 2013 Consumer Reports issue that the C-Max came to our attention.  Their favorable asessments of "ride, handling, quiet interior" and "drivers sit up high" generated enough curiousity to get us to the dealer for a test drive.  We would be perfectly happy with CR's 37 mpg average given everything else this car offers.  Luckily, we are currently exceeding this.  After our winter weather arrives and we add snow tires, 37 mpg may end up being closer to an annual average for us.

Our dealer purchased our first tank of fuel for us when we took delivery of our car on August 24th.  We hadn't heard about this forum yet and did not set the trip meter, but it looks like we may just break 600 miles on our very first tank.  My wife and I are thrilled to say the least.  Is it possible for us to join the 600+ club, if we make it, without the screenshot.  Or rather, can we send a screen shot showing total miles on the car?  Our mileage at delivery was documented by the dealer and we can calculate actual mpg.

Anyway, this is our very first new car and we are very happy.  We were expecting the mileage Consumer Reports reported, but according to our info screen we are averaging around 46 mpg.  So far, the C-Max has exceeded our expectations in every way.

My wife and I just took delivery of our C-MAX yesterday-our first new car in twenty-four years together.  We had to wait a week for our dealer to locate one with colors and options we wanted.

We are located in New York State between the Adirondack Mountains and the St Lawrence River.
