2015 Edge Brake Questions. Electronic e-brake etc...

[mhaynes]

Hello all, 

I am about to tackle a front/rear rotor and pad replacement for a friend and I have a few question regarding the rear brakes. The small shop they took it to, stated they "did not have the proper tool to do the brakes". From what I'm told, this vehicle is a 2015 w/ 2.7L Ecoboost. FWD with 18" wheels.

 

I'm assuming this has something to do with an electronic parking brake?

1) Am I required to put the e-brake into some sort of "service mode"? I've seen mention of this on 2013-2016 Fusions. Like this: https://www.youtube.com/watch?v=QuDCIysYAug and this https://www.knowyourparts.com/technical-resources/brakes-and-brake-components/ford-fusion-electronic-parking-brake-service-mode-procedure/. If this is the case, it appears the rear pistons are simply pushed back into place with a c-clamp (no twisting required)

2) Or do the rear brakes operate like the 2011-2014 Edges? By this I mean, they use a screw in type piston with no computer intervention.

3) Finally, are there any other tips or tricks any that you more experienced Edge folks can provide?

 

Your help would be greatly appreciated!

 

Happy wrenching

You need a caliper piston spin tool. You can get through Amazon for $21.00. Very easy to use, spin the piston back till it stops and then push back in the rest of the way. Very easy to do and use of the tool. Make sure  parking brake is not engaged! Good luck.

See the attached procedures. Yes, the rear caliper requires the special tools, and yes, the parking brakes need to be put into service mode. I think service mode can also be activated with ForScan. Also, take note of the front pads as they now have an adhesive to prevent/reduce noise and shudder.

Hi Mitch, 

Thank you very much for the quick reply. I will certainly be buying that tool for future jobs, it looks very easy to use and could be useful on other vehicles. However, I did not need that tool for this job. I'll try to explain my reasoning and procedure below.

 

I'll cover my procedure here in hopes it will help anyone else searching the internet abyss on this topic since I found very little help out there.

After seeing the vehicle in person this afternoon, it did indeed have an electronic parking brake on the center console which looked identical to the Fusion set up I had seen in the video I attached in my previous post. I assume Ford used the same sort of system here so I just tried the maintenance mode sequence described in the Fusion write ups and it worked.

1) Place the calipers into "Brake Maintenance Mode" using the sequence shown in the video here. It goes something like this....

           -Turn Ignition/Push button ON

           -Press accelerator pedal AND pull UP on e-brake button on center console

           -Continue to do this while turning the ignition OFF  (ie press pushbutton)

           -Turn ignition ON again while still holding both accelerator and pulling up on the e-brake button. 

          - You will hear the rear calipers working/whirring (presumably releasing pressure or simply unlocking them in preparation for pushing the pistons back in). Finally a message on the dash will appear. "Brake Maintenance Mode". You're ready to proceed.

2) Remove wheel

3) Remove caliper mounting dust caps. Remove caliper mounting bolts X2 (7mm Hex Key). Remove spring clip on the outboard side of the caliper with a flat blade screw driver. Remove the caliper and tie up and out of the way.

4) Remove caliper mounting bracket bolts X2 (15mm socket)

5) Remove caliper mounting bracket along with both pads. 

6) Bang the crap out of the rotor if you live in the rust belt like me, and remove it. 

7) As stated in the Fusion writeups/videos. The caliper piston "appears" to be the screw in type because it has the dimples that would normally indicate this. However, you do not need to screw these in to retract the piston. My hint here, was that the dimples did not line up with any "nibs" on the back of the old pads. No nibs were present on the pads AND the dimples on the piston were not oriented vertically as seen on previous Edge setups. See photo of piston below. Also, I applied very little pressure with a c-clamp and the piston began to retract easily. This was my sign to proceed as "normal" rather than use the twisting method. I just gently drove the piston home with a c-clamp and began reassembly.

8 ) Assembly is just the reverse (Yes, I hate when manuals say this too...) It was very straight forward so, no point in covering reassembly in detail here. Liberally clean with brake-clean, wire brush, lubricate slide pins. Etc...

9) Did the other side the same way.

10) Now onto taking the calipers OUT of "Brake Maintenance Mode"

              - Turn the ignition ON

              - Press and hold both the accelerator pedal AND push DOWN on the e-brake button on the center console

              - Hold for approximately 5 seconds and you'll hear a chime from the dash and the "maintenance mode" message will appear on the dash. 

              - Once the chime is heard, turn the ignition OFF (ie press pushbutton) while continuing to hold the accelerator AND e-brake button.

              - Turn the ignition ON while continuing to hold the accelerator and button. You'll hear a familar whirring noise from the rear calipers as they seat themselves. 

              - The "maintenance mode" message will disappear and you can release the accelerator pedal and button

11) As always, pump the brakes to ensure no air bubbles have entered the system. Go for a test drive and break in your new pads. 

 

Once complete, the car drove just fine. No sticking calipers, had firm pedal feel, e-brake worked as it should etc...Everything normal. If I've done something wrong here, let me know, but it appears all is well here. Now onto the fronts. Have to reorder the right size rotors since Ford isn't exactly clear on the diameter required by trim level.

Omar, 

I just saw your reply after typing my procedure. Thank you very much for sharing that incredibly helpful document with 3D models and exploded views. That procedure does, not specifically state that the piston has to rotated in order to be compressed and the figure appears to show a standard caliper compression tool (no twisting, simply a fancy clamp). So I think I'm good there. Forscan would have made obtaining "brake maintenance mode" much easier. Fiddling with a certain sequence of buttons, pedals and ignition switches took several attempts to get right.

 

Thanks for the tip on the adhesive required for the fronts. I'll be getting to those next weekend and that's likely something I would have overlooked.

 

Happy wrenching

I noticed the same thing, but two things made me incline towards the twisting method: First it does expressly state to rotate it at the end in case the piston bottoms out but was still not fully compressed and also has a note to not put over 20 Nm force when rotating.  The second reason is that it states to use a "General Equipment: Brake Caliper Piston Retractor" while for the Font pads it states to use a C-Clamp with an old pad.

 

Edit: By the way, thanks for the write-up, I don't remember seeing one for the 2015+ Edge, seems like the pads have a long life span.

If those pic are of the rear caliper, I'm so glad i painted mine. I've changed all 4 corners out on my '16 SEL & didn't run into any problems. Went with Centric Rotors with the special black coating to keep the rust & flaking down. 

[vega]

This comes just in time to do mine.  Thanks everybody!!!!

[mhaynes]

Omar, 

That's true I see what your referencing to. Your logic makes sense to me. It appears both approaches work, and I'll certainly reply back if I notice any adverse affects of simply pushing the pistons back in. 

 

lildisco, 

Yep, that's a 2015 with only 50k miles in Wisconsin winters. I would highly recommend painting components before they look like this. Ohh and purchasing the powder coated rotors would be ideal too. 

 

Vega, 

Glad it could help and good luck!

[lildisco]

If you're interested in my brake swap, here's what i did:

Clicky Clicky

 

Car is doing fine, swapped out the rear rotors with the same style that are on the front, Centric Premium Rotors. From Centric's website:

Centric premium rotors utilize an Electrocoating finish that provides long lasting corrosion protection. E-coating is a superior electro-statically applied finish designed to withstand 400 hours of salt water exposure without rusting. Phosphate finishes utilized by other manufacturers provide only minimal protection from the elements; these finishes are generally only effective for the shipping and storage portion of a rotor’s life. The addition of heat and moisture eliminates the effectiveness of phosphate finishes resulting in immediate corrosion once installed in the vehicle.
