1988 Porsche 911 3.2L Petrol · F525 CKR

A recurring brake caliper binding issue sits at the centre of this 1988 Porsche 911's roadworthiness record, with the nearside front service brake flagged as binding but not excessively at the 2021 advisory stage and the same condition reappearing as an advisory across both front wheels at the most recent test in June 2025. The intervening tests in October 2022 and October 2023 recorded no advisories at all, suggesting the caliper issue was either rectified or fell below the examiner's threshold for comment during that period before re-emerging. The single failure in September 2021 was unrelated to the brake concern, instead relating to an inoperative rear fog lamp switch and a non-functioning rear fog lamp, both of which were clearly remedied given the subsequent passes. The 2025 advisory being recorded across both front wheels rather than just the nearside is a noteworthy escalation and warrants close attention during any pre-purchase inspection. Recorded mileage stands at 10,397 miles over a 38-year lifespan, equating to an average accumulation of roughly 274 miles per year. The MOT history contains no test entries between 2021 and 2025 that would reveal intermediate mileage progression, but the very low annual figure overall points to extended periods of either minimal use or significant standing time. Vehicles of this profile typically suffer from dried and cracked suspension bushes, perished rubber brake lines, corroded brake hydraulic components, stale fluid throughout the braking system,硬化 fuel system seals, and oxidation within the cooling system. Long-term standing also places additional stress on the gearbox, clutch release bearing, and the flat-six engine's crankshaft, valve stems, and piston rings through oil drainage away from critical contact surfaces. Given the documented front caliper binding advisory, the immediate priority on inspection is a thorough evaluation of both front brake caliper slide pins, pistons, and guide surfaces for seizure or restricted movement, alongside the condition and flexibility of the front brake hoses and the rigidity of the flexible lines. On a road test, the buyer should listen for any grinding or rubbing noise from the front wheels immediately after setting off, which would indicate a caliper failing to retract fully, and should pay attention to any pulling to one side under braking, uneven brake disc wear visible as a lipped edge on the inner or outer face of either front disc, and excessive heat radiating from a front wheel after moderate braking. The handbrake and rear brake circuit should also be assessed, as a binding front paired with neglected rear components is a common pattern on low-mileage classics. Additionally, the 2025 test did not record any exhaust, suspension arm, subframe, or corrosion advisories, but the four-year gap in the available records means a comprehensive inspection of the suspension linkages, shock absorber mounting points, and underbody corrosion is essential, particularly around the front strut towers, rear trailing arm mounting points, and the longitudinal members where surface rust commonly progresses on vehicles of this vintage.
