- In this video I show my experience replacing the 2018 Mazda 3 Rear Brake Rotors. I accidentally let the pads wear out and therefore ended up with rusted rotors. After replacing the rear pads I wanted to see if regular use of the pads might wear off the rotor rust, but after a couple weeks effort it became clear that this would never happen, so I ended up at Autozone to buy some replacement rotors (roughly $60.00 a piece).
My vehicle had about 27,000 miles on it at the time of the rotor replacement.
Note: I don't show how to enter rear brake maintenance mode in this video, as I showed it my last video ("Replace Rear Brake Pads - 2018 Mazda 3...").
The written version is as follows (undoing this sequence is shown in the video):
1. Turn on ignition via 2 quick successive start button presses (for manual transmission don't push the clutch).
2. Push and hold the gas pedal to the floor, continue holding the gas pedal while then pushing down on the electronic parking brake.
3. Press the start button/ignition one more time to turn off the car.
4. Wait 2 seconds and then quickly turn the ignition back on (by again quickly pressing the start button twice).
When complete you should hear the rear parking brake mechanism contracting and you should see a warning light with a ((P)) on the dash.
Now you can let go of the gas pedal and the parking brake, and turn off the car. You are ready to perform maintenance on the rear brake system (don't forget to secure the vehicle against rolling.
Super helpful. I was starting to question whether I’d have to take the hub off to pull the rotor. Thank you!
That hole in the Rotor is a bolt hole, think you use size 10mm x 1.25 and put it in and turn to pop rotor off.
There looks to be a bolt hole in the rotor. I know when I did Toyoto rotors I was able to put use the bolt hole to push the rotor off.
I was going to make the same comment.
This helped me a lot, thank you!
I suggest you shop for car parts on RockAuto. You can get a complete brake change kit for less than $100.
Super helpful! thanks for making the video! But I really wonder why didn't you change the rotors in the first place when you changed the pads. They really look horrible...
I'm a guy, and I can be very curious sometimes. I wanted to feel the difference between old destroyed rotors working against worn out pads vs new pads working against old destroyed rotors...I thought the experience was worth it.
Wondering the same. I always do both at the same time.
Thank you for the help!
What happens if you don’t put it in maintenance mode
The pistons don't retract, so it will be difficult or impossible to have sufficient clearance for the thicker new pads. You "can" manually force the piston to retract, but don't do that, you risk damaging the rubber or worse the piston.

To see what happens go to Pine Hollow Auto Diagnosis and under Mazda group there is a vid called Brake Job Complications. Great vid.
Electronic parking brake...ahhhh!
PB BLaster is your friend. better than WD40.
