The 2017 W213 E220 model is experiencing brake judder and vibrations in the steering wheel.

[motorman3]

Greetings, I own a W213 E220 AMG Line with a mileage of 140,000 kilometres.

I have been experiencing brake judder and steering shaking for an extended period.

I replaced the authentic discs and pads on two occasions before receiving advice to repair the front wheel bearings.

After replacing the old discs and pads with a fresh set of authentic ones, the vibration issue has resurfaced after driving 300 miles.

What is the possible explanation for this?

The mating surfaces of the disc and hub may not be thoroughly clean. Even a little amount of rust or scale caught between the brake pads may be amplified near the edge of the disc, resulting in vibrations when braking. Performing a surgical cleaning with a wire brush and sand flap wheel should resolve the issue. Another potential cause, particularly if you drive and stop with smooth and gentle movements, is the accumulation of resins and similar substances on the surfaces of the disc and brake pads. An Italian brake tune-up will effectively resolve the issue.

*On a clear road, increase your speed to match the maximum allowed limit and then use the brakes forcefully a few times.

I have replaced the bearing, which includes the hub, so both front hubs on both sides are now new.

I shall attempt to alleviate the issue by engaging in abrupt deceleration and see whether it resolves the problem. However, I am really perplexed, since the vehicle's performance remains smooth for around 200 to 300 miles before the vibration reoccurs. This suggests the presence of an obstruction or distortion affecting the brake discs.

The technician informed me that the calliper does not seem to be the problem, as he has replaced the discs and pads three times and they retract smoothly.

Another issue I have noticed is a little vibration in the steering wheel when driving on certain highways. This might perhaps be caused by the front control arms, however I find it unlikely that they would cause the brake discs to deform.

Upon inspection of the suspension bushes, it has been determined that there is no noticeable movement. However, I am now perplexed by this situation.

I acknowledge that some W213 E class vehicles have this problem, but no one has found a remedy for it.

Some individuals suggest that the potential causes for the issue might be related to wheel bearing/hubs, front alloys, bushes, braking fluid, callipers, or tyres.

I am unable to sell the car in its current condition, hence I am essentially trapped.

An enduring perennial issue, which I have also encountered. The mileage required for replacement may vary depending on your specific automobile. However, I have just replaced the two outer tie rods of the steering arm, which has effectively decreased the occurrence of the "wobble" in the steering system. It is worth noting that both joints were worn out after covering a distance of 80,000 miles. Please verify the tracking information. I completely agree with the prior remarks on the importance of being meticulously clean. I still have a little instability, but my vehicle had a TUV test last week (the German equivalent of a MOT) and I specifically requested the inspector to thoroughly examine the front suspension. In addition to being placed on the wobbling table to inspect all the joints, the individual meticulously examined every component using a pry bar and other tools, and verified that everything was in excellent condition.

If you want assistance with the replacement of tie rod ends, please go to my YouTube channel (link provided in signature block).

I have seen this phenomenon on my current automobile, as well as on my previous vehicle. Although the control arms seem to be in good condition, one of them is likely to be inside damaged. This can only be discovered after it is eliminated. I need to update the front control arms on my automobile annually. When a ball joint is impacted, it undergoes oscillations in both the forward and backward directions. The occurrence of this issue during braking may lead to the mistaken assumption that it is connected to the disc or pads.
Typically, I see that as an indication to replace the control arms. Both of them are positioned on the strut. The right side will be the correct position. When the left side of the automobile's tires get worn, the car produces a metallic rubbing noise when it does a right turn. There is no sound when the right side is worn. There is just a judder sensation experienced while using the brakes.

Thank you for providing the information. I will surely go with it as my next course of action. In order to replace the control arms, as you said, I have been informed that one cannot determine or perceive any looseness until the arms are removed and the deteriorated bushings are inspected.

I have included a photograph and highlighted the arm that I believe it could be. Is it the correct one? The Mercedes suspension system consists of many control arms.

Thank you once again

I encountered the same issue. In 2006, the C220 Sport had recurring judder after 500 miles after replacing the brake pads and discs twice.
I replaced the severely rusted backplates for reasons that are unclear to me, and since then, I have driven around 8000 miles without any issues.
Uncertain if the absence of the backplate leads to overheating.
I used high-quality aftermarket components.

[QuirkyPixel]

Could you perhaps provide some clarification on the term "back plates"? Are you referring to the brake pads, or is there another aspect that I am overlooking? I am planning to replace the retaining pins and metal braked/spring mechanism, since the current pins, which are somewhat rusted, are impeding the free movement of the brake pads. I have reached the conclusion that the brake judder disappears in the cooler mornings but reappears when it becomes warmer, indicating that the issue cannot be attributed to the brake discs. This leads me to believe that the pins may be smaller in size when it is cold, allowing for better movement of the brake pads. If it proves ineffective, then it would have been a mere expenditure of €15.

Lately, I have encountered this issue. Based on the forum postings, it seems that many individuals are experiencing the same problem.

The issue in my situation has been identified as a deformation in the front wheel. The reason of the issue seems to be inconsistent, but it is a valuable avenue of inquiry for anyone experiencing the same problem.

Additionally, there is a Mercedes Service Bulletin addressing the same problem.

LI42.10-P-066910 AUG17 213 sans AMG, there is a noticeable vibration in the front brakes while braking. To address this issue, please inspect the state of the disc brake and brake pads, check for wheel imbalance, examine the suspension and steering elements and assess the contact surface of the wheel hub. If there are no visible or measurable damages to any of the components, then it is necessary to replace the brake pads.

Hopefully, this information proves beneficial to someone.

A substantial buckle would be required to induce juddering when braking.

I first installed aftermarket discs that functioned well for a few months, but subsequently, a noticeable shaking sensation began to occur. I provided two further replacements at no cost, and on the third occasion, I also replaced the deteriorated backplates.
I am unable to see the correlation, yet subsequent to that event, everything has been satisfactory. 15000 miles earlier.

In my own experience, I have found that there is often a connection between a worn track rod end and a front control arm link. An ocular examination will reveal no abnormalities as they look to be in satisfactory condition. Once someone begins to wear something, the others are essentially becoming obsolete as well. Currently, I am studying the C programming language independently. I need to do maintenance since there is brake judder. Since the issue is originating from the front right wheel, I will proceed to replace both the upper and lower control arms, the drop link, and the track rod end. This refers to the regular maintenance that is performed once a year, or if you are fortunate, every two years. The issue with service and maintenance timeframes is that they fail to consider the deplorable condition of our roadways.
I am not implying that this issue is specifically attributed to you. Providing my own perspective based on my experience dealing with these vehicles. Is the wheel bent or distorted? Possibly, but unlikely. As previously said, a visual examination will often reveal no significant findings, save for the possibility of a degraded rubber grease bush/cover (if fortunate).
What is the reason for replacing all of the components? As you progress over the course of many months, you will be continuously replacing each one individually, resulting in a never-ending cycle.
