Excellent videos ! I own a W221 myself and once you’ve driven an s class there’s no going back 😂 I served my apprenticeship as a Mechanic and we were taught to remove the cap from the brake fluid reservoir before depressing the brake calliper pistons as the excess pressure can damage seals within the master cylinder.

I usually clean and spray a light coating of antiseize on the hub before mounting a new rotor. Good job Sir.

[@LeighSr]

Nice suggestion! Thank you.

這是個很有質感的個人汽修頻道，也是值得學習的標竿。

This man makes great video on Mercedes 👍🏻👍🏻👍🏻👍🏻👍🏻

[@rlee3305]

Great video. I can see a common mistake you and most dyi make. you did not clean the corrosion off the hub before installing the new rotor. this will cause future problem. the corrosion will collect moisture and create more corrosion and cause the the new rotor to warp which will lead to brake pulsation. should always clean the hub and put a brush the hub with a light film of grease before installing the new rotors.

[@LeighSr]

Thank you and yes, you are right, I need to add the script into the video. I did not clean the hub because I have cleaned it a few months ago when I replace another pair of rotors. Those rotors are uneven leads to vibration when braking.

[@cesarbojorquez7418]

Another great video. Thanks. At some point I’ll have an s class, what a beautiful car.

[@LeighSr]

Thank you, and yes s class is the best Mercedes.

[@nikolayzhelev1097]

Hi. Great video, thank you. Excellent garage, clean and in order and great working discipline. I’m impressed. I noticed in 12:12 you have put some kind of thread locker on the brake caliper bolts. Can you please share the exact brand and model of the thread locker? Also, can you please advise what kind of lubricant you used on the brake pads surfaces before installing them in the caliper? I was wondering, the brake pads cleaner, that you used on the piston surfaces in 04:50 isn’t it dissolving over time the piston seals? What is this cleaner based of?

Well done. Nice and clean.

Love your videos !! sir

[@nyc1dxo537]

First I like your video editing. Absolutely fantastic. But a question regarding rotors. MB OE rotors have that grayish protective coating. I see you didn't remove the coating while installing but yet the video switches to a cleaned rotor. Did you find an issue after you installed the uncleaned rotor? I did replace mine and neglected to clean one of the sides.

[@LeighSr]

Thank you and you watched the video very carefully. To the re-editing video I using some different footage that looks better, lol. The coating on the rotor should be cleaned by the brake pad instead of cleaning separately. Just install them and drive, everything should be ok.

李sir你好、我的車子是2012 Mercedes Benz C 350 M276 engine , 我車子上星期二突然打不著engine 而當按keyless button時、我聽到有二下engine kick kick聲、我連續試了四次最後打 得著engine了、但是transmission 被鎖了P 不讓我轉RND、我為有關上engine再從新打著engine , 終於可以打著engine及可以轉去D了、但是engine light on , 之後同一天去 了幾個地方關了幾次engine也可以打著engine 、回家後我關了engine等了兩小時、再打著engine 而且engine light off 了。 請問一下為什麼會怎麼樣？ ？ 第二我上綱看過有人說如steering lock壞了也是打不著engine、不過是連kick kick 聲都不會有、而且返車行整要$2700加元很貴的、請問一下李sir會不會教學 換steering lock motor ??? 因為換motor不用program 是嗎？ 我是想問以上兩個問題,謝謝,

You are really professional and I learn a lot from you, but you used zimmermann rotors are better than Brembo?

[@LeighSr]

Thanks and I have no experience with Brembo, but it away better than original genuine.

[@dserduk]

Nice video. Just wonder about bolts that hold caliper and pads . Did you reuse them ?

[@LeighSr]

Yes, those can be reused. Because there is no requirement to replace on WIS of MB.

[@vladimirortiz1923]

Where do you bought the repairs manuals from? Tks.

[@LeighSr]

The WIS comes with MB star SD connect C4, and I bought it on ebay.to/2NlYWWO

Rotors looked like Zimmermann, which is German brand

您好！我第一次换的时候大约是5万英里，这个视频是因为第一次换的原厂刹车盘抖动，大约是6万英里。

Is copper based lubricants applied to the guide rails?

By the color, I think that’s copper based lubricant.

李師父～謝謝您的分享。我的車是2015ML350～1年多前3萬1千Mile的時後做了B Service車子少開，現在開了3萬4千多Mile，有提示要做A9 Service已超過兩百多天，可以告訴我A9 Service包函什麼嗎？而且只開了兩千多Mile,需要馬上做這個Service嗎？謝謝您感恩。

[@LeighSr]

您好！ 这个Ax Service的保养已经没有具体的定义了，主要还是依据各种保养的间隔。我把从08年到现在奔驰发布的保养手册都发布到www.leighsr.com/forum/garage/the-maintenance-manuals-of-mercedes-ben-chi-bao-yang-shou-ce 您可以按照您的车型的间隔来进行保养，可以参照最新的手册。我发现奔驰比较新的保养要求比以前的间隔更小了。 各种保养的间隔不仅仅依靠里程数，时间也是一个重要考量，如果开得不多，但时间到了，也要及时保养。

Do you have a video on how to replace the resceptacle or terminal connector on the ignition coil? You have to de-pin and install to a new one.

[@LeighSr]

Sorry for the late reply. I do not have the video of replacing the receptacle, since I did not damage one. I think that should be teardown the old receptacle to take out the pin and insert them into the new one.

[@LeighSr]

I just checked the part number is A 027 545 50 26

@@LeighSr Yeah they have similar engines but I broke the resceptacle connector. I bought one resceptacle but I just want to make sure how to de-pin the wires and connect to the new one.

[@cesarbojorquez7418]

@senior Leigh. How long did your brakes lasted? I see you have similar video from a year or so ago.

[@LeighSr]

Actually this is a re-editing video for the video last year. And I expect the brake pads last four years and the rotors last double of rotors.

[@cesarbojorquez7418]

Nice. I have very similar brakes on my SLK I paint them last year. I love how they look now and not difficult. If you decide to do it let me know and I’ll send you some Mercedes or AMG decails for the calipers as gift for your help.

[@edwinhandybuddy1038]

李老师您好。我正在找一辆w221，我一直倾向于自吸引擎M273。最近市场上有一辆13年，近20万km，考虑到m278是涡轮引擎，是否可以入手？买的时候要注意些什么？谢谢🙏

[@LeighSr]

建议M278涡轮增压引擎，您会爱上她的。20万公里8年的车有点多，但如果按规定保养的话是没问题的。一听，二看，三试。 听发动机运转是否平静；看底盘是否干净无油迹，车身关键部位有无碰撞痕迹；试驾减震舒适度，加速和刹车。
