2014 Mercedes-Benz C 2.1L Diesel · V28 AAC

Brake wear and front suspension play dominate the MOT record, with rear‑disc condition flagged in the latest test and front‑disc wear noted a year earlier, while ball‑joint play on both front lower arms has been a recurring advisory since 2021. The vehicle has passed every MOT since a dangerous tyre failure in 2020, but the pattern of brake‑disc advisories and persistent suspension‑joint play suggests that wear on these critical safety components is progressing and will likely require attention before the next service interval. At 94,327 mi over twelve years the annual average of roughly 7,800 mi is typical for a saloon of this age, indicating steady rather than abusive use. The MOT history shows roughly yearly testing with no prolonged gaps, apart from the close‑spaced July 2020 tests, which reflects consistent road use rather than long periods of storage. This mileage level places the brake discs and suspension joints within the wear window where thinning and bearing play become common, aligning with the recorded advisories. When inspecting the brakes, measure the rear‑disc thickness against the minimum specification and compare it with the front discs, which were also noted as pitted. Look for any pulsation in the pedal, increased stopping distances, or a high‑pitched squeal under light braking – all signs that the discs are nearing the end of their service life. Examine the brake pads for uneven wear and ensure the calipers move freely; any binding could accelerate disc degradation. For the front lower suspension, feel for any looseness or knocking when the steering wheel is rocked at low speed and when driving over bumps; slight play in the ball joints often manifests as a vague clunk or a wandering feel in the steering. Inspect the bushings and ball‑joint housings for corrosion or torn boots, and verify that the steering geometry remains true. Given the tyre advisories – a nail in the near‑side front, edge wear on both rears, and perishing sidewalls – conduct a thorough visual and tactile tyre inspection, checking for cuts, bulges, or uneven tread, and confirm that tyre pressures hold steady. Replacing any compromised tyres will be essential to restore full compliance and safe handling.
