2017 MINI ONE 1.2L Petrol · CL67 AND

The most recent MOT test on October 14, 2025, at 42,618 miles confirms the vehicle remains roadworthy but reveals a concerning trend in the braking system. While no major failures have occurred, the rear brake discs were noted as worn, pitted, or scored—indicating accelerated wear—and the rear pads were described as wearing thin. This follows a 2024 advisory for brake imbalance, suggesting the system has required repeated attention. The absence of defects in earlier tests (2023 and before) implies the issue is recent, likely exacerbated by either deferred maintenance or a failure to address earlier warnings. The vehicle’s current status is technically compliant, but the pattern of rear brake faults suggests a need for urgent inspection. The mileage progression shows unusually low annual mileage, averaging just under 4,700 miles per year over the past nine years. This is significantly below the UK average for a vehicle of this age and class, particularly when compared to the 10,000–15,000 miles annually typical for heavily used urban or commuter cars. The gaps between tests are consistent—annually in October—with no abrupt spikes or prolonged periods of inactivity, which might otherwise raise concerns about storage-related issues like fluid degradation or corrosion. The steady, low mileage could indicate either light usage or extended periods of non-operation, though the latter would typically manifest in other areas of the vehicle’s condition. A prospective buyer should prioritise an immediate inspection of the rear braking system, focusing on the condition of the discs, pads, and calipers. The 2025 MOT’s description of pitting and scoring on the discs suggests potential uneven wear, which could lead to binding or reduced efficiency. The 2024 imbalance advisory further implies the possibility of uneven pad wear or hydraulic issues, such as a failing master cylinder or contaminated brake fluid. Beyond brakes, the vehicle’s suspension components—particularly rear bushes and coil springs—should be examined for wear or corrosion, as these are common failure points in MINI models of this era. Given the lack of defects in earlier tests, structural integrity appears stable, but the brake history warrants thorough verification to confirm no underlying hydraulic or mechanical faults have been overlooked. The 2023 and earlier tests provide no red flags, but the recent braking issues demand careful scrutiny. While the vehicle has not failed an MOT, the recurring advisories indicate a pattern of neglect or deferred maintenance. A buyer should not assume the current compliance will persist without intervention, particularly if the brakes have not been serviced since the 2024 test. Independent verification of fluid levels, hydraulic pressure, and caliper operation is essential to avoid unexpected failures.
