2011 Mazda 6 2.2L Diesel · A9 EHA

The most recent MOT, carried out on 20 July 2026, was passed but returned several advisories concerning rear brake disc condition, rear brake imbalance, and corrosion of both rear suspension arms and the rear sub‑frame. Over the preceding six years the pattern of advisories has been largely consistent, with recurring notes on rear brake wear and imbalance, progressive corrosion of rear suspension components, and tyre tread approaching the legal limit. While no outright failures have been recorded, the frequency of brake‑related advisories suggests a maintenance trend that is not improving and may be edging towards a point where corrective work will become mandatory. At 82 379 mi the vehicle averages roughly 5 500 mi per annum, which is well below the typical usage for a 2011 model. The low annual mileage points to periods of light use or extended storage, which can be beneficial for overall wear but also raises the possibility of age‑related deterioration such as rubber hardening, battery sulphation, and corrosion of metal parts that are not exercised regularly. There are no large mileage spikes in the MOT record, indicating the car has not been subjected to intensive short‑term high‑kilometre use that would accelerate wear on the drivetrain or suspension. Prospective buyers should give particular attention to the rear braking system. The rear discs are already described as worn, pitted and scored, and the brakes are noted as imbalanced. On a test drive listen for any pulsation or uneven feel when applying the rear brake, and feel for a pull to one side under braking. Measure disc thickness and check for excessive run‑out; replacement of the rear discs and a full brake bleed, together with a professional re‑adjustment of the rear calipers, will likely be required within the next few thousand miles. The rear brake pads should also be inspected for remaining thickness, as thin pads can exacerbate disc wear and lead to overheating. Front brake pads were flagged as thin in 2020, so a visual inspection of both front and rear pads is advisable, and replacement should be considered if the friction material is below the minimum specification. The corrosion advisories on the rear suspension arms, sub‑frame and lower arm bushes merit a thorough visual and tactile examination. Look for any rust flaking, cracking of the metal, or excessive play in the rear wheel bearings and rear toe settings; any clunk or knock over bumps could indicate that the arm bushes are perished and need renewal. Tyre tread on all four corners is already at the legal limit, and given the vehicle’s age the rubber may be perishing even if depth appears acceptable – check the sidewalls for cracking, dry rot or bulges. Verify the condition of the battery, especially its cranking voltage and electrolyte level, as long periods of inactivity can reduce capacity. Finally, confirm that the engine oil, coolant and brake fluid have been changed at appropriate intervals; fluids degrade with time and can cause internal corrosion or reduced braking performance if not refreshed. A full service history, including any recent suspension or brake component replacements, will help gauge whether the car has been proactively maintained despite its low mileage.
