2021 Dacia Duster 1.3L Petrol · SC21 CWG

The vehicle is currently roadworthy, but the maintenance history reveals a concerning trend regarding brake system corrosion. In the most recent test on 19 May 2026 at 55,548 miles, the car failed due to excessive corrosion on both front brake pipes and the nearside rear pipe. While it passed just two miles later, the tester still noted the nearside rear pipe was corroded and covered in grease. This suggests the previous repair addressed the immediate failure without resolving the root cause of degradation across the braking lines. The mileage pattern is consistent with a five-year-old vehicle, averaging approximately 11,110 miles per year. Data shows a steady progression from 35,885 miles in May 2024 to 45,906 miles in April 2025, reaching 55,550 miles by May 2026. This regular usage indicates the car is driven consistently rather than sitting for long periods, which generally helps mechanical components function but explains the wear-related corrosion seen on the brake lines. A buyer must conduct a thorough physical inspection of the entire braking system to ensure no further corrosion exists beyond the replaced pipes. The recurring failure for brake pipe corrosion in 2026 indicates that the environment or lack of underbody protection accelerated rust on the metalwork. Additionally, the 2024 failure for mismatched tyre sizes on the same axle suggests a past lack of attention to detail regarding basic maintenance. You should verify that all four tyres are of the same specification and brand and check for any further structural damage to the sidewalls that was flagged in previous advisories.
