2018 Brake Squeal is Design Problem
I am convinced BMW has improperly designed the Brake System & that faulty design is why most X1 brakes squeal like you are running over babies.
The squeal is grating & distracting. I believe the Brake Rotors have natural harmonics inherent in their design and those harmonics are the root cause of the horrible & distracting noise. I support lighter vehicles were it makes sense. Are there any heavier, better designed, rotors available for the X1 ? I am ready to get rid of this thing. BTW: I am a Mechanical Engineer with 20 + years aerospace experience. I have tried every trick I know to stop the squeak. Not possible with this design. |

Does this happen in the morning or after the brakes have warm up? The original pads may contain metal parts that oxidize in a damp/wet environment, after washing the car or even after or even after spending the night.
Have you tried changing the brake pads? I use carbon-fiber ceramic one and no squeaky sound whatsoever. Cheers. Last edited by mDrive2; 02-09-2024 at 07:40 AM.. |

From 5K miles after new brakes began to squeal. Louder & more obnoxious as they heat up. I replaced them with BMW best Ceramic Pads (w beveled leading edge) and best new Rotors. I dial indicated the rotors at less than 0.0002", both sides (expected for ground surface). Brakes squeal 2K miles later. I took it apart to see that the "Anti-Squeal" material on the piston side had worn completely through in 6 small spots exactly where the piston made contact. Rotors were re-indicated and still flat. This is a classic signature of a Harmonics Design Problem (think Tacoma Narrows Bridge Disaster).
I am having a hard time believing I'm the only one on the planet who is unhappy with this. |
