2012 Great Wall Steed SE TD 4X4 2.0L Diesel · AE12 GYP

The vehicle is currently roadworthy, but the maintenance history reveals a concerning trend of recurring brake system corrosion. While the most recent test in January 2026 at 133,334 miles passed, the tester identified a corroded offside front brake pipe covered in grease. This indicates that while previous failures were addressed, the underlying issue of rapid oxidation on the hydraulic lines has not been fully resolved. The mechanical trend is unstable rather than improving, as the vehicle continues to flag brake-related defects despite multiple repairs in 2023 and 2025. At 133,334 miles over 14 years, the vehicle averages approximately 9,500 miles per year, which aligns with typical usage for a 4x4. The data shows a significant period of activity between November 2023 and January 2025, where the vehicle covered over 7,400 miles in just fourteen months. However, the gap between the February 2025 test and the January 2026 test, with only 7,156 miles recorded, suggests the vehicle may have sat stationary recently, which often accelerates the corrosion of metal components seen in the brake lines. A buyer must conduct a thorough physical inspection of the entire braking system and drivetrain. The 2023 and 2025 failures highlighted excessive corrosion on multiple brake pipes running from the ABS pump to the rear wheels, suggesting the vehicle is vulnerable to environmental rust or poor protection. The previous collapse of the central prop shaft bearing in late 2023 also necessitates a close check for vibrations or play in the driveshaft assembly. Given the history of emissions failures in late 2023, the engine's combustion health should be verified to ensure no further internal degradation is occurring.
