2012 Porsche Cayman 2.9L Petrol · RO12 BTF

The vehicle passed its most recent MOT on 25 February 2026 at 58,813 miles, but the trend is clearly worsening. A test just eight days earlier on 17 February 2026 resulted in a failure for identical brake pipe corrosion, significantly worn front brake discs, worn rear discs, a sticking horn, an excessively fluctuating offside front service brake, and underside corrosion. While the subsequent pass suggests some remedial work was undertaken, the recurrence of corroded brake pipes and worn discs within days indicates an underlying, active deterioration in the braking system that was not fully resolved. The recorded mileage pattern shows very low average annual use of approximately 4,201 miles per year over 14 years. However, a notable acceleration occurred between the January 2024 test at 55,321 miles and the January 2025 test at 58,339 miles, an increase of 3,018 miles in one year. This was followed by a further 474 miles in just over a month leading to the February 2026 tests. This recent spike in usage likely contributed to the rapid manifestation of serious brake component wear and highlights that low historical mileage does not preclude recent, intensive use that has stressed consumables. A buyer must inspect the entire brake hydraulic system with extreme prejudice. The repeated failure for corroded brake pipes from the calipers, covered in grease or other material, suggests a long-standing leak or contamination issue that compromises braking reliability. The inner brake disc wear on both axles, described as significant and obvious in the failed test, points to caliper binding or uneven pad contact. The fluctuating offside front brake noted in the failure is a critical safety concern that must be rectified. Furthermore, the persistent 'underside corroded' advisory across the last two tests warrants a thorough examination of the chassis, suspension mounting points, and subframes for structural integrity, as corrosion in these areas is a serious, non-consumable defect. The earlier 2025 test also flagged a slight play in the offside front lower suspension arm ball joint, a component that should be checked for worsening play during a physical inspection. The stuck horn failure, while a minor electrical fault, adds to the picture of neglected or deferred maintenance. Given the age, the combination of active brake system corrosion, disc wear, and structural corrosion advisories signifies a vehicle requiring immediate and substantial investment to achieve sustained roadworthiness. The low overall mileage is offset by the severity and recurrence of the faults identified in the final months of the MOT record.
