2016 Suzuki Celerio 1.0L Petrol · SP66 THV

A chronic and escalating pattern of brake pipe corrosion dominates the mechanical history of this 2016 Suzuki Celerio, with every recorded MOT since 2023 flagging the same underlying condition across all four main brake lines. The most recent test on 25 August 2026 saw the vehicle pass, but with advisories still in place for both rear main pipes being corroded and covered in grease, alongside a nearside front tyre worn close to the legal limit on its edge. Tellingly, the same date carries a separate failed entry showing the tyre pressure monitoring system as a major defect, meaning the car could not be legally driven until that issue was resolved. The brake pipe advisories have progressed from a single nearside rear concern in 2023 to all four lines being flagged by 2025, and they have now narrowed again to both rear mains in 2026, suggesting either partial replacement has taken place or the front lines were treated and the corrosion has migrated or returned. Combined with a 2024 advisory noting that parking brake efficiency was only just meeting requirements and that the braking system required adjustment or repair, there is a clear and consistent narrative of deferred brake system maintenance that has now spanned four consecutive tests. The recorded mileage of 129,452 miles against an age of approximately ten years equates to an annual accumulation of roughly 12,945 miles, which is notably high for a small city-oriented supermini of this type and well above the average for the sector. The mileage progression implied between the 2023, 2024, 2025, and 2026 tests is consistent and shows no obvious gaps, indicating the vehicle has been in regular and sustained use rather than left standing. This higher-than-average annual mileage carries direct mechanical implications, particularly for the brake and suspension components already showing signs of wear, as the brake pipes have been exposed to several winters of road salt and moisture at elevated cycle rates. Consumables such as brake pads, discs, tyres, and suspension bushes will also have absorbed significantly more thermal and mechanical cycling than a lower-mileage example of the same age, accelerating the onset of wear-related defects. For a prospective buyer, the brake pipe corrosion should be treated as the primary area of concern and physically inspected underneath the vehicle on a ramp or with the wheels removed where possible. Look closely at the four main brake lines running along the underbody and rear axle, paying particular attention to any pitting, surface rust breaking through painted coatings, or evidence of fresh joint repairs, and be prepared to budget for a full brake pipe replacement if the corrosion has compromised the metal wall thickness. On the test drive, listen for any knocking or clonking from the rear suspension over speed humps and uneven surfaces, as the higher mileage increases the likelihood of worn rear beam bushes or shock absorber mounting deterioration, and check for any pulling to one side under braking which could indicate a sticking caliper or a flexible hose weakening under pressure. Verify the operation of the parking brake on an incline, since the 2024 advisory noted its efficiency was borderline, and confirm that the handbrake holds the vehicle securely on a steep slope without excessive travel. The tyre pressure monitoring system should be confirmed as fully functional, with all four sensors communicating, and the nearside front tyre inspected for uneven inner or outer edge wear which could point to suspension geometry issues such as worn wishbone bushes or a deteriorating track rod end. Finally, given the sustained high mileage, request evidence of recent replacement of the cam belt if fitted, check the condition of the engine oil and coolant for any signs of emulsion or discolouration indicating head gasket concerns, and ensure the clutch operation feels progressive without slipping under load, as these are all items that accumulate wear in line with the vehicle's evident working history.
