"Check Brake System"

[Meanderthal]

I replaced the brake pads on my BS just after getting it home, so that I would have ceramic pads instead of the organics, which should produce a lot less dust. I did do a lot of other little modifications at the same time but the only other thing I can think of that might affect the braking system is installing the HRG Lift Kit. That kit requires moving a mounting point for the ABS wire. Now I am constantly greeted by this error message every time I start the BS.

After that message I also see warnings for:

• Full Accessory Power Active
• Hill Start Assist Not Available
• Service AdvanceTrac
• Pre-Collision Assist Not Available

Then the "Brake" light stays lit along with ABS and the little circled lightning bolt.

Anyone have any ideas on what might be causing all this. The warnings all seem to be brake related and the brakes are very weird. I need to get this sorted before the snow flies.

did you try a hard reset, by disconnecting the battery for 5-10 mins?

I just did that with no change in results.

I forgot to mention earlier that I hooked up my BlueDriver ODB2 code reader but it did not show any codes related to this issue.

Sounds like you damaged the sensor. Had too much drop in the line when installing the strut assembly back in. Or pinched the line and spilt it. I’d say you need a new sensor

I would have taken it to my Dealer at the start and tell them no one else gets so much dust, fix it ! Warranty and all that.

An update: Today I was out driving around running some errands. When I returned home, I got out my laser thermometer and checked the rotor temperatures front and rear. It appears that the front brakes are not working at all. Front rotors were about 75-80F and the rears were 150-160F.

I’m going to take a closer look at the ABS wires tomorrow when it is a bit warmer than it was today.

fuse check probably quickest and easiest
I'd start there

It appears that the front brakes are not working at all. Front rotors were about 75-80F and the rears were 150-160F.

That's a pretty big clue. Ceramic pads do not absorb heat the way other pads do, which means the heat goes into other brake components. With ceramic pads on the front the front rotors should be hotter than the rear rotors.

As far as I know, no matter the brake pad material, the front brake disc should be hotter than the rear. They are larger and usually vented but also should carry up to 75% of the braking energy.

They definitely should not be room temperature.

Correct, the front brakes do most of the heavy lifting (stopping). My 2006 Escape has had several front brake rotor and pad replacements. The rears…….still original.

The front disks are larger because they are designed to do most of the braking work. Because they are larger they have more surface area to dissipate heat, so they won't necessarily retain more heat. Ceramic brake pads transfer more heat to the rotors (and other brake components), so if you have ceramics on the front but not the rears the front rotors should be hotter. They for sure should not be room temperature!

I dropped it at the dealership today. Here’s hoping they can figure out what the problem is. I’m glad that I don’t have to drive it in the snow/ice the way that it was. One day of that was more than enough (rear brakes only, no ABS, no traction control, etc). I got really lucky and they just got a few brand new Escapes for loaners. Mine had 7 miles on it, so I’m the first to drive it outside of Ford or the dealership. A grand total of 3 miles from there to home. We are due for another round of snow tomorrow night. Most of Tuesday’s snow is gone now thankfully.

I got it back from the dealer last night. It turns out that it wasn’t anything I did and must have just been coincidental that it showed up right as I finished all the changes. Here is the wording from the invoice:

VERIFIED CUSTOMER CONCERN. PERFORMED SELF TEST USING FDRS TO CHECK CODES. FOUND C1034:96 STORED IN ABS MODULE. CHECKED OASIS USING DTC. NOTHING FOUND. REFERRED TO DTC CHART AND PERFORMED PP TEST K. K1 N K2 Y REPLACED ELECTRIC BRAKE BOOSTER ASSEMBLY. PERFORMED BRAKE BLEED, FINAL QUICK TEST AND ROAD TESTED VEHICLE TO VERIFY REPAIR. NORMAL OPERATION RESTORED. CUSTOMER CONCERN RESOLVED. WARNING LIGHTS DID NOT RETURN.​

​

It appears this must be a rare occurrence, since I have not seen anyone else report here that they have had a brake booster failure. Maybe someday this thread will be useful to someone else that has a similar issue.

Thanks for the update. I seem to recall at least one other report of a brake booster failure, although I can't remember if it was here or over at Reddit's /r/broncosport.

Glad to hear you got it back and a reasonable explanation for the issue.
