How To Change 4th Gen Mazda 3 front brake pads and rotors

Changing the front brake pads and rotors on my 21 3 premium

[@VintzDesert]

Dealership wanted to charge us $900 for changing the fronts so I’ll be visiting this video again in a few weeks. Thanks for this

[@jakecoyne3919]

Never go to a dealer. They only make money through service calls. Find yourself a local mechanic and they'll normally do it for at most 200-250 per axel if they're putting in good quality. So to charge 900 for 2 is wild, it should be close to 960 for them all

[@alb0zfinest]

@@jakecoyne3919I actually did pay this price (well more actually $1000 for just the front ones), but I was worried sometimes at these private shops they rush and get things wrong. I did an oil change in a local shop and they used the wrong oil lmao. So yeah it's a gamble.

K3UF the dealer. 🙂

Came here just to check if there was anything non-standard involved. Glad to see it's just your typical brake job with no BS!

[@Songbird2357]

Me too!! I was totally expecting some hidden trickery.

[@luciusvorenus1870]

Cannot thank you enough for this one, man! Planning on doing my brakes soon and this is a huge help.

Hey man, whenever you do the rears, could you please make a video for that as well?

[@Apex_MZ3]

Will do!

Ive seen your car at the porsche dealer towards the beggining of this year. Crazy how I found my way to this. Great vid btw

[@Apex_MZ3]

Lmao I work there. Glad the video helped!

[@ms.b9093]

Brakes needed replacing after a year into ownership? The pads did not look that bad. I hear rotors on these 4th gens warp easily from the factory.

[@username-mark]

Ok so im not exactly mechanically inclined but this looks easy enough for me to do. Almost like rotating your own tires easy. If so, why go to a garage to have it done??

[@shellyshamsul6112]

This is one of the best breaks replacing video. I feel very confident. Thanks a lot!! Any recommendation what after market brand and where should I buy them from? First time changing breaks.

[@XAINIx]

Can you please make video on rear brake pads too 😊

[@crm1225]

It’s the same process, but you also have to put the electronic parking brake in maintenance mode. The rear rotors are smaller than the front. Check online for the specified torque values on the two sets of bolts - they differ between the two sets, as well as from front to rear

[@jeremyspicher6408]

About to try brakes for the first time on the cx30. Wish me luck

[@AntonioTito-nj8ww]

Thank you so much from Italy! pls add more videos like this

[@Trapan93]

Hey, when pushing the caliper piston back in, did you need to crack the brake fluid reservoir cap to release pressure at all? ive seen that it is recommended for other cars, this will be my first Mazda job. Thanks!!

[@Apex_MZ3]

Nope, no need to. That’s really only done if there’s air in the system, but you would bleed the brakes if so

[@jedironin380]

Thanks for asking, I had to do that for some of my other cars. 😉

[@nicolasramos856]

Do you finish tie all that bolts whit any torque wrench?

[@sukh527]

Going to use this video to change the brakes on my wife's car using a kit I got from RockAuto. Many thanks man.

[@pmonk1177]

Great video, I'm planning on changing my rotors soon on my Mazda. At 1:48 would you happen to know the model number on your Milwaukee tool??

Will this work for my 2024 cx30?

[@yasaako]

What is this gun type ? For opening the bolts? The one you used for caliper not the wheel

[@Apex_MZ3]

@@yasaako The red one? If so, it’s an electric ratchet

[@danielrafetzeder459]

Thanks for very Helpfull Video. One Question tho, do i need to replace to Pad Clips, or can i leave the old ones in?

[@Apex_MZ3]

You can reuse the old ones if they’re in good condition. Highly recommend to clean all the brake dust off of the old ones to minimize possibility of brake noise

[@scottrabbitt3122]

Question, when changing front or back brakes, do you have to put the car in maintenance mode to disable the E-Brake so it’ll be easier to push the caliper pin back in? Or is it required to do so on the back brakes.

[@Apex_MZ3]

@@scottrabbitt3122 you only need to do that for the rear brakes

[@scottrabbitt3122]

@@Apex_MZ3 Good to know. Thanks.

[@gfgiuliano]

This is a super helpful video!!! Thank you man

[@jacobholasek]

Does anyone know with the rear brakes do I need to spin the piston caliber when compressing it or just compress it normally

[@MrDaveB123]

Does you car have a maintenance mode ? If so please let folks know about it because that lack of knowledge when I did mine cost me a shit ton of money when the parking break wasn't shut off

[@Apex_MZ3]

@@MrDaveB123 the front brakes don’t have a service mode, only the rears

[@smilz7263]

How much do you have to tourqe the bolts? Looking to do the brakes on my 2019 Mazda 3 but I cant find any Info on the tourqe specs online.

[@Shawncc3535]

Are the rears any different

[@Apex_MZ3]

They’re identical except that you have to put the caliper into service mode before you compress the piston or you’ll damage them

[@AwVer]

Great video thanks for making this. Are the rear much different?

[@Apex_MZ3]

Same process but the rears need to be put into service mode as they have an electric parking brake

[@timothysmith7700]

The service manual says not to turn it when compressing. Now I’m confused

[@Apex_MZ3]

@@timothysmith7700 you are correct. I looked at the wrong service manual

​@@timothysmith7700 are you talking about the rear brake caliber pistons? do they need to be rotated when compressing them?

[@flipztuh24]

Everything else we're correct except for except for. Do you know what it is? You forgot to torque down the bracket bolts and caliper bolts most important things.

[@AK-oz4ew]

6:11 - missing cleaning the dirt from the caliper piston with a brass brush before compressing it all into the body. There is a lot of deposit over there. Great video otherwise

[@soccertg0376]

If the brakes are pulsating, getting the rotors cut on the car can solve the issue, make sure to cut them on the car as theyll be cut how they spin on the car and not on some random machine.

[@tomaszmk5368]

Good job 👍

[@jwsnyder5021]

Thanks for the video, but just changed those little mouse brakes for Corksport's front big brake kit...

Doing my front & back in a couple weeks, this video helped a lot! Do you have a video for the back because of the parking sensor or electric parking? whatever’s goin on back there lol

[@Apex_MZ3]

I don’t have a video yet since my pads haven’t really work in the rear and I’m at 66k. I’ll make one once I have to do it

[@jessanthonypatasin7410]

great job. this really is a good help. One thing I wanted to ask is how do you do the rears? i believe it has EPB(emergency parking break).. TIA

[@nhow4]

Cars that have an electric e-brake just need to be put in service mode for that. It’s different for all cars, but someone on KZbin did a video on how to do that. Basically put car in auxiliary mode, depress brake, push brake button, push start button 3 times while still pressing brake button. You should see brake light go off. And when you want to turn service mode off, you basically do the same thing but pull brake button up instead of down.

[@asantehunter]

Hey, do you need to put the vehicle in any kind if special service mode ? Both times after changing breaks i had a ton of syntem errors

[@Apex_MZ3]

You don’t have to be in service mode for the front brakes. You do when doing the rears as the electric parking brake needs to be disengaged

[@kingk3302]

I’ve just been noticing some shaking at low speeds from the wheel. I was suggested to change the rotors. Is this common?

[@Apex_MZ3]

Yea that’s pad buildup on the rotor. Make sure to change your pads as well so you get and even contact with the new rotors

[@hwdan3096]

8:35 as you are remounting the caliper, the spring clips are no longer there?

[@Apex_MZ3]

They should be there. I forgot to install them so I removed the caliper and made the clip showing where they go and never made a new clip of reinstalling the caliper

[@wallydelarosagomez]

I turned my maintenance mode on to replace my rear pads and rotors but accidentally turned it back on while disassembled. The caliper spit out the piston on the driver side. I also had compressed the piston using a regular tool instead of the suggested one, so you know if I’ll need to buy a whole caliper or if buying a piston + caliper repair kit will do? Trying to save on costs as much as possible. Rockauto currently does not have a caliper for 2021 mazda 3

[@Apex_MZ3]

If the piston isn’t marred I would clean it very well and reuse it. Bleed your brakes and go for a drive around the neighborhood at low speeds and check for leaks. If none, you saved it

[@wallydelarosagomez]

@@Apex_MZ3Thanks for the tip. Could I send you a pic of the piston? I also compressed it originally using a normal compressing tool, later noticed this piston has grooves inside, so I’m not sure if that could’ve damaged it

[@jacobholasek]

rear brakes next?

[@justinone6993]

Holding in the disk?

[@stephenaguiniga7960]

How did you like the pads? I’m putting these on the rear.

They’re not bad. I have about 20k on them so far and they’re holding up

Should i bleed the brake lines when doing this?

No need unless you’re at the interval when it’s due
