- How to install rear brakes on 2020 and 2021 BMW M340i G20. This is how to do the rear brakes on g20 BMW. The electronic rear emergency brake adds some confusion. Even with a different style rear e brake you still don't have to spend a fortune to do the brakes. If you want to save about $800 per axle and not go to the dealer then follow this video. I spent an afternoon or about 3.5 hours with filming to do the front and rear pads. My cost was $147 usd with all parts. It's EASY and you can do it. No special tools and no scan tool needed. If you know how to reset the oil change reminder than resetting the brake change reminder is the same!! Just cycle through the menu. If not ask me and I'll help you. Or watch my BMW oil change video and at the end you can see how to reset reminder inside the car.
I used Powerstop Z23 pads and Powerstop brake sensor front and rear. Parts were ordered from Rock Auto. Part Numbers: Front pads Z261867 Rear pads Z232220 Front Sensor SW0498 Rear Sensor SW0496 If you have Questions let me know! I do my best to actually help.

Great video, no BS, straight to the point, love it!
UPADATE : YOU DON'T NEED TO WIND THE MOTOR ANTI CLOCK WISE AFTER THE PROCEDURE..
JUST START THE CAR, PUMP UNTIL ITS HARD ,THEN APPLY HAND BRAKE AND RELEASE COUPLE OF TIME.
(THERE WAS MANY CONCERNS ABOUT THE MATTER HERE ,THATS WHY I JUST MENTIONED THIS HERE)
By the way this man done a great job ,I appreciate that so i liked and subscribed you..
Keep doing...excellent
I THINK BETTER TRY TO NOT TO OPEN THE DOOR OR ACTIVATE THE IGNITION WHILE DISCONNECTED THE EPB MOTOR CABLE..
Lol Clayton make sure to use Jack Stands you're placing A LOT of faith in that jack
Tried doing mine earlier this year but ECS sent me the wrong brakes and it took weeks so I just ended up going to the dealer but usually work on my own cars glad to see this video up tho
Thanks for the information, You are a Bold Man doing this!....!!
Never scared to fail. Thanks
I did this yesterday… the automatic rear brake can be released with a size 6 all on key if you put it in further so you don’t damage the splines…
Thanks for sharing. Different process and slightly different order to which I would use, but still works and just goes to show there is more than one way to skin a cat.
Nice car 👍
Did you buy the sensors separately bro?
Turn the motor back anticlockwise after installing the brakes and before putting the electronic Brake
I didn’t turn it counter clockwise after installing the rotor and brakes. Nothing happened. Once I turned my car on, it automatically went back to where it was supposed to be. Is there anything that could happen if you don’t turn it counter clockwise after the pad change?
That’s not necessary. Nothing wrong with doing that if you want to, but no need.
I will replace my rear rotor’s next week on 330e 👍
How do you find these pads in regards to stopping performance compared to the BMW pads?
Is it necessary to replace pads, rotors and sensors? Message on my dash said check the pads. My car is a 330i 2021. BMW Charging me $947. We only drive it on weekends. I think I'm getting screwed. Never heard a sound from the car nor has difficulty breaking. Your opinion please 🥺
There are two messages you can get. One is a maintenance reminder and one is a wear indicator type message. What did your message say?
You did not mention about turning the motor again (probably anti clockwise this time????) after installing brakepads?
Yeah he didn’t !
It’s not required.
However it’s best practice to use a scan tool or ISTA to service the rear brakes, thus avoiding the need to remove the EMF actuator. This will retract and then later reset the EMF actuator.
The piston can also be wound back by rotating it with a tool, again avoiding the need to remove the actuator.
Motor go after resistance . No need to turn it . When he feels resistance he stops
I changed the brake pads but need the sensors for my 2020 m340i. Do you think you can link me the specific sensors I need to change in order to reset my brake light 🙏🏽

I bought the powerstop brand ones
Do you have to do anything special like rewind that electric actuator for the e break?
Good job Clayton but ... why you didn't use the gloves? ;)
For the E-brake motor did you have to turn it back during re-assembling? Does the brake faults have to be reset on the dash?
Same question I had
I just hit 24k miles on my 2022 m340i and the pads are low all around. Do you think I could get away with just doing the pads and cutting the rotors or should I replace rotors as well? Please let me know your thoughts thank you!
I haven't touched my rotors yet. Have changed pads twice. 67k miles. Everything is perfect. Rotors still look great. I road course race car and go through lots of rotors when they crack from heat, to me these street driven rotors are in amazing shape. You could cut but unless there is a flaw in the rotor I wouldn't touch them. Are you doing the work yourself or shop?
@@ClaytonYatescarenthusiast thanks for the advice! I’m going to be doing them myself. And yea I’d say my rotors are still in great shape, running your finger across them there smooth and should be fine for a pad swap. The current pads still have a little bit of material left so it’s not like it’s gone metal to metal.
I’m going for brembo pads in the front and the powerstop ones for the rear. I also don’t like the initial grabyness of the stock pads, it’s annoying sometimes getting the car to smooth stop. $220 total on rock auto for the wear sensors and all pads have placed the order!
I have a 2019 330i with M sports brake (blue calipers), will the pads fit on them?? i think the m sports brakes are same on m340i and 330i.
Yes they show the same part number. Go to rock auto and go through their guide. Step by step right to the pads.
i just got the Z26-1867 for the front of my 2022 M440i base and the caliper pins did not fit in the holes. would the Z23-1867 fit the same? PLEASE PLEASE HELP somebody
Before doing the actual work, do you have to put this in BMW service mode?
I didn't but I have an app along with obd link lx where I can. I wanted to find a way anyone could do without special tools. It worked perfectly but there maybe a better way and following service manual is recommended. If you search 2020 bmw m340i service manual there is Google docs available of the full service manual for free on one of the forums. Pretty awesome manual. Literally has everything. I recently replaced an exterior door handle base assembly using it. Those manuals are pretty expensive.

7th comment down. The 330i is also available on this same post, 5th post
how do you feel with the powerstop brakes? performance loss since install? how is the dust? let me know
thanks
They're not as grabby as the oem pads but I actually did a track day and 3 auto x events on them and they never faded. I got them way way past their operating temp range and although smoking a bit never fully faded. Brake dust is half if not 75 percent reduced. I eventually bought gloc race pads for front. Now I switch when I go to the track and back to powerstop any street driving. Good pads just don't have the instant bite of oem or race pads. Oem brake system is strong so even a less aggressive pad will work great.
@@ClaytonYatescarenthusiast thanks man
@@ClaytonYatescarenthusiast also another question, you decompressed the piston with the torx bit clockwise.. did you do it counter clockwise to put it back? Could I simply use a scanner to compress and decompress the piston?
@@GarageNineteen it'll decompress on its own. Not sure on scanner to be honest. I know bmw has a method different. From my understanding this is only way without special tools such as bmw scanner or other that work with bmws.
@@ClaytonYatescarenthusiast alright cool! Thanks man
Just use a tester and brakes will unwind for service...
5:56 Is that cable you replaced so that the car reads the brake pad life?
Does that have to be replaced every time brake pads are changed?
Only has to be replaced if they worn down enough to hit it. It's pretty common to just replace them everytime anyways due to being cheap insurance. Apparently people have issues in the past reusing them.
@@ClaytonYatescarenthusiast Thanks for the quick reply 🙏 Yeah figured the brake sensor cables need to be replaced (BMW conveniently also gets more $$$)
The Stealership wanted $501 USD to replace the rear brakes, they're tripping
I'll most likely be replacing my girl's rear brakes on her 2020 330i and making a video 🎥.
What's absurd is that she only has 13k miles and we're here in Southern California so there's not much external factors to wear them prematurely.
5 girls in my family have this 3 Series, 2 M340's, and 3- 330i's, so I want to learn a thing or 2 about them
how do you do the base model brakes ? front and rear
Very similar just everything is smaller
Any reason why you chose Z26 for front brakes and Z23 for rear brakes?
Odd reason for most but sometimes I auto x this car and it needs more rear brake bite. The z23 has more bite when cold. For any type of racing besides auto cross this wouldn't work. But since pads don't get hot enough during a autox event it works pretty good. Doesn't make much of a difference though. Z26 holds more heat in theory therefore requires a little more heat to achieve best bite. If I didn't auto x race it then I'd run z23 front and rear. Better street pad.
What was the mileage on your car when you changed the pads? They looked like they still had a lot of life left in them.
I think 35k ish miles. The rear sensor was going off. It had worn to the sensor. Did have a decent amount left though. Maybe 30%
@@ClaytonYatescarenthusiast I guess I have a lot more on mine with only 9300 on them. I have a scan tool, if I back off the E brake with it I assume I do not have to remove the electric motor, just push in the piston.
Mine has 13k and makes wierd break noises i don't think the pads are worn off
Any ideas?
Where did you buy your brake pads at?
Rock auto.
Will this work with a 2020 330i x drive
There are some similarities but the brakes are mostly different. So not really like this. Sorry
Is it a noticeable difference in driving with these pads. I have a 2020 rwd model with about 58,000 miles. I’m torn between getting these or the stock ones from fcp euro for about 290. I have the stock brake pads on the rear but am thinking of getting the power stop for my front. I daily the car and am planning on going stage 2 tune.
A lot less dust. They hold up plenty good. I actually tracked it around 2 heavy braking race tracks at full pace when it was making 500 wheel on e40 on these pads. They faded but held up way better than I'd expect. And I'm a time attack driver so not like i was easy on it. For the street and some auto x these are great pads. They don't have the aggressive bite the factory pads have when newer but that's a feel thing only and I don't like the grabbyness of the stock pads and neither did my wife for street driving. Honestly I'd rather these pads over factory. All the braking ability is still there just more linear. The brake dust is a huge bonus and bmw pads are extremely over priced for what you get and old school tech with high levels of brake dust. Hope that helps.
@@ClaytonYatescarenthusiast thanks for your response it helps a lot. One more question, I have a 2020 model but I bought it used and it came with software 7.2021. I’m pretty sure I need a bench unlock but just wondering if you knew if this software was tuneable
how necessary is it to replace that sensor?
Well if you worn down to it then has to be. If you didn't you can reuse it no problem. Also I ended up running some race pads for track days and swap these pads in and out for street and I actually zip tied my sensors up out of the way. So not even using them.
@@ClaytonYatescarenthusiast gonna get the sensor anyways, rather have a new one than not. thanks man!
Would unplugging it cause a brake light?
How come you didn’t show how you push the cyclinder in
3:21
Great video, thank you!
If you don’t have the proper tools I would avoid doing this though! I used the same tools as in the video and apparently need new actuators and calipers from the motor being stripped and pistons being damaged. $4k in repairs now 😬
what?? how did this happen? did you maybe strip a thread by accident?
I guess by forcing the the piston to release? The car also has to be in service mode so the piston can retract properly apparently
@@gracemanning3220 Did you use the T40/45 bit to turn the motor clockwise until it stops before pressing the pistons in? That is equivalent to putting the brakes in service mode using the bmw electronic tool. What year/model is your bmw?
@@gracemanning3220the car doesn’t have to be in service mode, I’m not sure what that is to be honest.
The rear brakes can be put into service mode using a scan tool or ISTA, which is best practice, and avoids removing the EMF actuators, however can be done this way without issue, and can also be done a third way, by using a piston winding tool, again avoiding removing the actuators.
Bimmerlink is a good phone app that can be used for service mode on the rear brakes.
Autel have various scan tools which can do this, but the best option is to use ISTA D or ISTA +, which is what dealerships and approved independents use.
I'm that 5% bro I drive hard and fast like the car was meant to be driven. I need the braking performance and don't care about the dust. Other than that lol, decent video
