2012 Mercedes-Benz B-Class 1.8L Diesel · BW12 ABO

The vehicle exhibits a distinct pattern of accelerating brake wear that culminated in a dangerous failure just one day prior to the most recent test, despite the current pass status. The Dec 2nd pass confirms the replacement of the dangerously worn rear brake pads, but the advisory regarding rear brake discs worn, pitted, or scored with lipped edges indicates that the braking system was already under significant stress. This progression from advisory status in November 2022 to a dangerous failure in November 2025 highlights a rapidly deteriorating component that requires immediate mechanical attention. With a recorded mileage of 92,755 miles over approximately 14 years, the annual accumulation of roughly 6,625 miles falls within the expected range for this vehicle class, suggesting the car has not been subjected to extreme usage. However, the rapid deterioration of the rear braking components relative to this mileage implies that the rear brakes may have been neglected for a significant period prior to the November 2024 test, or that the vehicle is frequently used in stop-start traffic conditions which accelerate pad wear. The absence of failures or advisories in the 2022 and 2023 tests suggests the vehicle was roadworthy for a longer duration before the current wear pattern emerged. Prospective buyers must prioritize a detailed inspection of the rear braking system, specifically checking the condition of the brake discs for deep scoring or excessive runout which can cause vibration through the steering wheel or brake pedal. Given the history of lipped edges on the discs, verify that the rear calipers are not binding and that the brake hoses are free from cracking or swelling, as these issues can prevent the brakes from releasing fully. Additionally, while the chassis and suspension have not been flagged in recent years, a test drive over uneven road surfaces is essential to confirm there are no underlying suspension noises or steering alignment issues that might have been masked by the recent brake work.
