ChatMaven Posted August 12 Share Posted August 12 Greetings, everyone. I am experiencing brake judder, a common issue, with my 2014 model E class vehicle. The symptoms include pronounced vibration experienced during deceleration from high velocities. I perceive the vibration in the brake pedal and vehicle floor, but there is no sensation sent via the steering wheel. Uncertain whether this is related to electronic steering that eliminates the feeling in the steering wheel. The front brake and discs were replaced in February, while the rear brakes were serviced around 10 months ago. Since there were no indications related to steering, I presumed that the issue was with the back part of the vehicle. Altering them yesterday had no impact. I will dismantle the front and perhaps replace them as a last option. However, some individuals have had significant difficulties in identifying and resolving this vibration issue. I would much appreciate any advice or suggestions. Thank you. Quote Link to comment Share on other sites More sharing options...
TechWhiz Posted August 12 Share Posted August 12 Attempt it at a low temperature. If it functions well, then it may be inferred that the issue is with excessive heat causing the discs to deform. Quote Link to comment Share on other sites More sharing options...
bvlenci Posted August 12 Share Posted August 12 The issue at hand is the concerning problem of hub run out. To address this, it is crucial to ensure that the surface is well cleaned. Afterward, the brake rotor should be installed and checked for any run out. If everything seems to be in order, it is possible that a flexible hose restriction or a sticky calliper may be causing one brake pad to not make proper contact. In such cases, the most cost-effective solution would be to consider trading in the automobile. Quote Link to comment Share on other sites More sharing options...
ChatMaven Posted August 12 Author Share Posted August 12 Putting humour aside, I am contemplating pursuing that course of action. If I am unable to identify any clear options, I could consider selecting an additional set of discs. I would consider purchasing a run out gauge, however it is unlikely that I will have any future need for it. I will not engage in excessive financial investment, as others have attempted.

TechWhiz Posted August 12 Share Posted August 12 Alternatively, you might have a garage address the issue, ensuring that it is resolved correctly. This approach would also provide you with recourse in the event that the problem persists. Â Quote Link to comment Share on other sites More sharing options...

ChatMaven Posted August 12 Author Share Posted August 12 What is the most effective method to do a test for it, please? Wouldn't it typically adhere? Quote Link to comment Share on other sites More sharing options...
Blu_Ray_UK2007 Posted August 12 Share Posted August 12 Elevate the vehicle, rotate the wheels. Observe if the rear brake discs exhibit uneven temperature distribution on one side of the vehicle after a drive with little braking. Quote Link to comment Share on other sites More sharing options...
ChatMaven Posted August 12 Author Share Posted August 12 Allocate a duration of 60 minutes from your daily schedule to remove the wheel, extract both slider pins, cleanse them well, and apply white lithium grease, which is compatible with rubber materials. Eliminated the pads, used the brake pedal many times to facilitate the emergence of the piston, albeit not completely expelled, as expected 😂. Inspect the piston ends for indications of rust or pits, thoroughly clean them, and then reinsert them. Perform the same action on the other side. A brake that is stuck will often emit a foul odour and cause your saliva to evaporate rapidly if you spit on the disc. I like the girl named Thua, just like a hawk. Expectorate on that object Quote Link to comment Share on other sites More sharing options...
ChatMaven Posted August 12 Author Share Posted August 12 I was always frightened to pump the brakes with the pads incase the caliper shot right out Quote Link to comment Share on other sites More sharing options...
Blu_Ray_UK2007 Posted August 12 Share Posted August 12 It will not, just have someone apply gentle pressure to the brake and see the piston extending outward. To be honest, they are around 1.75 inches in length. You simply need to extend it by around 20mm. Quote Link to comment Share on other sites More sharing options...
ChatMaven Posted August 12 Author Share Posted August 12 Will the flow cease when they disengage the brake pedal? Quote Link to comment Share on other sites More sharing options...
Blu_Ray_UK2007 Posted August 12 Share Posted August 12 Indeed, it is only the downward stroke that generates the necessary force to propel the piston outward. Quote Link to comment Share on other sites More sharing options...
