    The procedure that I detailed is exactly the same as the procedure set out in Step 2 in the table on the first page of your pdf document. Wording is slightly different, that is all.

    As I read it, this is the normal reset procedure when doing a routine oil change, not one that has been prompted by a warning light.

    Agreed?

Once again, Mazda have provided a means for us to do it and it its not unlike the EPB procedure but takes place in the fuse box. I will post it up when the time comes (or pass it to Tomcat who does a really nice job!!!).
    Hi, new to the forum. Glad I found it!! Thanks for the epb Maint procedure.
    Was wondering if you documented the above oil reset procedure and if so provide a link?

    Regards

    Thanks for the info on EPB maintenance mode! My CX-5 sat for a few months and the rotors rusted pretty badly. The front rotors seemed to clean themselves (pad ground rust off), but the rears never seemed to take the rust off. When going into maintenance mode, I could hear that the passenger side motor took far more time to retract then the drivers side - and after removing the pads, the passenger side was almost down to the metal, while the drivers side had about 25% life left. I installed new rotors and pads, and maintenance mode now sounds even and relatively short. BTW, the bolt to screw into the rotor to remove it is M8 x 1.25. Thanks again!

    Take care if this is the case, there was a mod done to the calipers to stop them from binding. The dealers will replace calipers under warranty but after that youíre on your own. The fault would allow the brake to bind and one or both sides to wear prematurely.

    Thanks for the info - unfortunately my CX-5 VIN is in the affected numbers, but has almost 60K km on it. I don't use the parking brake much, and will note from now on if it pulls to the side even slightly when released. "Warrantable within 20,000 km / 12 months in service hereafter Prior Approval required" means they might have covered it after the 20K/12 months? (I tried the parking brake just now, and it seems to release evenly) Thanks again

    Did you keep the old pads and discs? You could try and support a claim with them? The worst they can say is no. We get 3 years warranty here.

    loud metal clunking sound when braking

    just a heads up you guys, I didn't properly align the caliper notch with the pin on the rear pads and got a loud metal clunking sound when braking.

    I disassembled the brakes and found out what I did wrong, I didn't do the slight adjustment to line the caliper notch with the pad pin..

    Is there a visual mark of where the notches have to be ? It's a blind mate when the caliper goes over the pads so there's no visual to make sure they are exactly lined up... thoughts ?




    Sidenote: I find the OEM brake pads (the ones made from Japan, not the Mazda Value ones) to be the best in stopping power,
    I tried the Wagner Thermoquiet Ceramic pads , although they were quiet, I found them to have very subpar stopping power and they felt mushy when braking hard

    Thanks for posting this, just completed the procedure (the wrong way) so I'm saving this for future use.

    Why not just buy an ODBII Scan Tool with Electronic System Actuation & Reset Functionality and simply reset the EPB from the scanner before manually retracting the calipers and then go finish your brake job. Besides, if you are replacing pads, then EPB must be reset anyway to re-index pad location relative to the EPB motor - if the system does not re-learn the air gap between the two on its own.

    My CX-5 is a 2018 and had squeaking coming from the rear brakes when I would first start driving after it sat for awhile. They would squeak when braking or even just rolling along at speeds under 10mph. Warm or cold temps wouldn't matter. Eventually it would go away once the brakes warmed up, but always came back after they cooled down again. None the less it was driving me CRAZY coming from my 1 year old car that only has 7K miles on it. I took it to the dealership and they told me the pads were still over 95% and that it was "normal" for this kind of car. They said they could try resurfacing the rotors for $$$. I called major lazy BS so decided to change the pads myself to see if it helped and guess what, it did!

    Thanks to this thread I was able to do the whole pad replacement process myself so I really appreciate all the comments everyone made. I've changed brake pads before, but never with an EPB so I was a little apprehensive. Knowing about maintenance mode was extremely helpful. I made sure to change the hardware clips and use brake grease because I really think those were the problem, not the pads themselves. I still changed the pads just to be sure. I believe Mazda uses semi-metallic pads which could also be contributing to the noise, but the front brakes never make noise so it didn't add up to me. I also owned a 2014 Mazda 3 GT before this car and it never made noise either.

    After I changed the pads and got everything put back together I went to take the car out of maintenance mode and the EPB motor ran for what seemed like way too long and then it just stopped and the yellow and red parking brake warning lights stayed on the dash. After taking the wheels off again and taking a look I remembered that when I had compressed the piston back it left a small gap between the new pad and the piston (even with brand new thickness pads). All I did was compress straight back, making sure the notches in the piston were north/south so they would line up with the pin on the back of the pad, so I couldn't understand why it wasn't working! I thought maybe the EPB motor was broken at first (of course blame it on the car, not the user, haha). I decided to watch the EPB motor while it was trying to re-engage and I noticed it would just spin the piston around and it wasn't actually making contact with the pad or grabbing the pin. So I took the caliper off again, lined up the piston notch, and then bolted the caliper back on. This time, before I turned off maintenance mode, I pressed the brake pedal down so that it would compress the piston up against the pad and lock the pin and the piston notch in place vs. leaving the gap like the first time. When I turned off maintenance mode it caught the pin and worked like a charm! Apparently when the EPB motor tries to compress the piston and close that gap, it can cause the piston head to spin and take the notch and pin out of its original alignment. This prevents the piston from making full contact with the pad and the system thinks there is something wrong with the EPB.

    I had no experience with EPB before, so this was new for me. I seriously panicked a little when I couldn't get maintenance mode to go off so figured I'd share my experience just in case someone else has the same problem.

    Thanks for sharing your experience. It definitely would help those who want to DIY on rear brake pad replacement with EPB.

    Forgot to ask did you put a new set of OEM pads or aftermarket pads to resolve the squeaking issue? If it's an aftermarket set, which brand did you get?

    this is very helpful !!! I think this happened to me , see my post #22 above, I didn't know I had to compress the brake first befire turning off maintenance mode,

    my notch did not line up with brake pad pin and I kept hearing a cracking noise when I pressed the brakes as I drove.

    It turned out the notch was slightly un-aligned with the pin as you can see in the photos.


    No where in the Mazda procedures does it say that you have to press the brakes before disengaging the maintenance mode, but it defintely makes sense to do it..

    thanks AK-CX5 for heads up!!!!!!! it'll help a lot of members I think.

    Sorry for the late response yrwei52. I did not replace them with Mazda pads because, from what I've read, they are semi metallic and more prone to squeaking. It's so weird because the front ones have been just fine since I bought the car. I ended up going with ceramic replacements on the rears. The kind I got are Power Stop 17-1846 Z17 Evolution Plus Premium Ceramic Brake Pads. You can get them on Amazon or RockAuto for about $30 and they come with new hardware clips. The Power Stop website tells you to do a "break-in" process after you've put them on which is basically a few hard slow downs and then driving around until they cool off to set the resin on the rotor. They were a perfect fit and so far they have been working great. No more squeaking, finally!

    Did any of you disconnect the negative terminal on the battery after going into maintenance mode and before disconnecting the electrical connector to the electric parking brake motor gear unit? Or did you leave battery connected and have no issues disconnecting the EPB connector?

    I looked at the 2018 CX5 workshop manuals posted here: https://www.mazdas247.com/forum/show...-for-2018-CX-5

    After going to the dropbox link provided by Schatzi0217, I navigated to "Workshop Manuals" -> "Brakes" -> "Conventional Brake System". In that folder, I viewed the "REAR BRAKE DISC REMOVAL INSTALLATION.PDF" and "REAR BRAKE MOUNTING SUPPORT REMOVAL INSTALLATION.PDF" files.

    In both guides, the first 4 steps are the same:
    1. Switch to maintenance mode.
    2. Disconnect negative battery terminal.
    3. Remove wheel.
    4. Disconnect the electric parking brake motor gear unit connector.

    Just wanted to see if anyone has done step 4 without doing step 2 and didn't have any issues.

    Thanks.
