2019 MG ZS 1.0L Petrol · YN19 KRO

Rear brake disc deterioration is the defining theme of this 2019 MG ZS's record, with the same advisory for worn, pitted or scored rear discs appearing at both the August 2024 and July 2025 tests, accompanied on each occasion by rear tyres worn close to the legal limit. The most recent examination in January 2026 returned a clean pass with no defects recorded, which suggests the flagged items may have been attended to in the interim, though the record alone cannot confirm replacement parts were fitted. Across five recorded tests the car has never failed, so the overall picture is one of consistent roadworthiness punctuated by a recurring, low-grade wear pattern concentrated at the rear axle rather than any structural or safety-critical defect. Recorded mileage stands at 41,710 miles, an average of roughly 5,960 miles per year, which is modest for a seven-year-old vehicle. Testing has been annual and consistent, with no gaps in the record, though the interval between the July 2025 and January 2026 tests is notably short at under six months, indicating either an early test or a change in the testing cycle. Light annual use of this kind is consistent with the wear pattern observed: rear discs on lightly used cars frequently corrode and pit faster than they wear through friction, because the rear brakes do relatively little work and surface rust is only scrubbed off intermittently. The low mileage also means consumables such as tyres may be ageing as much as wearing, which aligns with the repeated advisories for tyres worn on the edge. A prospective buyer should focus inspection effort on the rear axle. Examine both rear brake discs for lipped edges, heavy scoring or a corroded band around the outer circumference, and on a test drive listen for grinding or scraping from the rear under light braking and feel for any judder through the pedal, which would indicate uneven disc surfaces. Check the rear tyres for tread depth across the full width, paying attention to the inner and outer shoulders, since edge wear was specifically noted; uneven shoulder wear on a car of this type can also point to rear alignment issues, so note whether the car tracks straight on a level road without steering correction. Beyond the flagged items, the absence of any advisories concerning suspension components, corrosion of load-bearing structures, or emissions across five tests is a positive factual observation, though it does not by itself establish mechanical condition. Given the short gap to the January 2026 pass, it is worth asking the seller for invoices relating to rear brake and tyre work carried out between July 2025 and January 2026 to confirm whether the advisories were rectified or simply dropped below the threshold of note. A pre-purchase inspection of the rear braking system and a check of tyre age and condition would provide the most useful reassurance on this particular vehicle.
