2015 Mercedes-Benz C 2.0L Petrol · MM64 AAY

The most recent MOT test completed on 31 January 2026 resulted in a pass, but the inspection history reveals a downward trend regarding the condition of the braking system. While the vehicle showed no defects in 2022 and 2024, the two most recent tests have both issued advisories concerning the brake discs. In 2025, the discs were noted as being pitted or scored all around, and by 2026, the front discs were flagged as worn. This indicates a progressive deterioration of the braking surfaces, suggesting that while the vehicle remains roadworthy, the components are approaching the end of their serviceable life and will require timely replacement. The recorded mileage of 62,038 miles for an eleven-year-old vehicle represents a very low annual usage rate of approximately 5,640 miles. While this suggests the engine and transmission have experienced less mechanical wear than a high-mileage equivalent, such low usage often implies the vehicle has been subject to long periods of standing or short, infrequent trips. Mechanically, this means that while the drivetrain may be in good health, other components may be suffering from age-related degradation rather than mileage-related fatigue, necessitating a focus on time-sensitive rather than distance-sensitive maintenance. During your test drive, you should pay close attention to the braking performance to assess the severity of the recorded advisories. Listen for any grinding or rhythmic clicking sounds from the front wheels, which would indicate significant scoring on the discs. Be alert for any brake shudder or a pulsating sensation through the brake pedal during deceleration, as this is a primary symptom of unevenly worn or warped discs. It is also advisable to check for any signs of binding calipers, which can cause uneven pad wear and overheating, particularly if the vehicle has been stationary for extended periods. Given the low mileage and age profile, you must also conduct a thorough physical inspection of age-sensitive components. Examine the tyres for sidewall cracking or perishing, as rubber degrades over time regardless of tread depth. Check the condition of the battery and ensure the service history reflects time-based fluid changes, specifically for brake fluid and engine oil, which can lose their protective properties through oxidation and moisture absorption. Finally, inspect the underside for any signs of corrosion on the suspension bushes, coil springs, and exhaust system, as vehicles that sit idle are more prone to surface rust and seized components.
