2004 Mercedes-Benz SL 3.7L Petrol · YK04 AAG

A recurring theme of brake system issues defines this vehicle's history, specifically chronic brake pipe corrosion flagged between 2020 and 2022 and a major ABS fault that led to a failure on 2025-03-24. While the record has since stabilised, culminating in a clean pass on 2026-03-24, the persistence of corrosion advisories over several years suggests a vulnerability in the braking infrastructure. The recorded mileage of 91,617 miles is low for a twenty-two-year-old vehicle, averaging approximately 4,164 miles per year. Such a low rate of accumulation often indicates a vehicle that has spent significant time stationary or has been used primarily for short journeys. Mechanically, this usage pattern can lead to the degradation of rubber components and the onset of corrosion in areas where moisture traps, which aligns with the previously recorded brake pipe issues. Given the major failure regarding the anti-lock braking system warning lamp in 2025, it is essential to verify that the ABS system is fully operational and that no warning lights illuminate upon ignition or during braking. During a test drive, the driver should feel for any unusual pulsations in the brake pedal or a lack of modulation during hard braking, which could indicate an unresolved or recurring electronic fault within the ABS module. The history of corrosion across all four brake pipes between 2020 and 2022 requires a physical inspection to confirm if these lines were replaced or merely treated. A visual check should be performed for any signs of bubbling paint or surface rust on the pipes, particularly where they are clipped to the chassis. Additionally, while a tyre cut was noted in 2021, the current condition of the tyre sidewalls should be inspected for any new perishments or cuts that may have developed due to the vehicle's low annual usage.
