2021 Isuzu Trucks Grafter N35.125 1.9L Diesel · LL71 VUS

The most recent DVSA MOT test on the 2021 Isuzu Trucks Grafter N35.125 was conducted on 2026-05-29, resulting in a clean pass with no recorded defects. However, the vehicle’s MOT history reveals a concerning pattern: it failed on 2024-12-16 with two critical failures—parking brake inefficiency below 50% of required function and rear brake axle imbalance—indicating a deterioration in braking system integrity. The subsequent MOT on 2024-12-19 passed without issues, suggesting that the failures may have been addressed but not without residual concerns. While the intervening period shows stability, the prior failures underscore the need for cautious scrutiny, particularly regarding the rear braking assembly and parking brake mechanism, which could recur if not properly maintained. The recorded mileage of 25,572 miles for a vehicle aged five years represents a relatively low annual usage rate of approximately 5,114 miles per annum, which is unusually low for a commercial or heavy-duty vehicle of this class. Such low mileage often correlates with extended periods of inactivity, particularly if the vehicle was stored rather than driven regularly. This can lead to specific wear patterns, including potential corrosion from moisture exposure, particularly in the brake system, suspension components, and exhaust assembly, where standing fluids and stagnant air may accelerate degradation. Additionally, the lack of substantial mileage accumulation means consumables like brake pads, tyres, and fluids may not have been subjected to the same levels of wear as a higher-mileage vehicle, but this also raises questions about whether the vehicle was adequately serviced during its low-use periods. For a prospective buyer, the most critical areas to inspect are the rear braking system and parking brake mechanism, given the historical MOT failures. Visually inspect the rear brake discs for signs of uneven wear, corrosion, or glazing, which could indicate the imbalance failure observed in 2024. Listen for a consistent braking noise or a shuddering sensation when applying the rear brakes, as these may signal binding calipers, warped discs, or misaligned components. The parking brake should engage smoothly and hold the vehicle securely when engaged; if it fails to do so, the mechanism may require professional assessment. Additionally, check for any fluid leaks around the rear axle area, as this could signal failing seals or seals in the brake system, which may exacerbate the imbalance issue. Beyond the braking system, the vehicle’s low mileage suggests potential issues related to prolonged standing, such as corrosion on the frame, suspension components, or exhaust manifold. Inspect the suspension for any signs of rust or corrosion on the coil springs, wishbones, or suspension bushes, which could lead to premature failure if not addressed. Check the tyres for sidewall perishing or cracking, which can occur even at low mileage due to age-related degradation of the rubber compound. Test the 12-volt battery and associated electrical systems, as prolonged inactivity can cause battery terminals to corrode or cables to loosen. Finally, consider the state of the engine oil and coolant, as these fluids can degrade over time, even without significant mileage, and may require a full service or replacement if the vehicle has been stored for extended periods. If the vehicle has a service history, verify that the manufacturer-recommended intervals for fluid changes and component inspections were adhered to, particularly during the low-mileage periods.
