2020 Vauxhall Grandland X Business ED NAV T 1.2L Petrol · R333 AAY

A clear pattern of brake-related advisories has emerged across the last three MOT tests on this Grandland X, with the most recent examination on 29 January 2026 returning a clean pass and no defects recorded. However, the preceding tests in 2025 and 2024 both flagged rear brake disc corrosion, specifically on the inner faces, alongside front brake pad wear noted in 2023. The 2025 test additionally recorded both rear tyres as being worn close to the legal limit, with the nearside noted as very close. While none of these items resulted in a failure, the recurrence of brake disc pitting on the inner faces suggests the discs have been progressively deteriorating and may now be approaching the point where replacement becomes necessary rather than simply being monitored. The overall trajectory is one of stable roadworthiness with a defined wear pattern centred on the braking system and rear axle consumables. At 42,968 miles over roughly six years, this vehicle has covered approximately 7,161 miles annually, which sits comfortably within the typical usage band for a car of this age and class. There are no extended gaps in the MOT testing history that would suggest a prolonged period off the road, and the mileage accumulation appears steady. This level of use means the braking components, tyres, and suspension have experienced a reasonable but not excessive workload, allowing mid-life service items to wear naturally rather than being driven to premature failure. The absence of advisories relating to suspension components, corrosion, exhaust integrity, or structural items across all recorded tests indicates that the chassis and underbody have held up well under this routine usage profile. Given the documented advisory history, particular attention should be paid to the rear braking system during any pre-purchase inspection. The persistent inner-face corrosion on the rear discs warrants a careful check for disc thickness, ridging at the outer edge, and any pulsation through the brake pedal during moderate to firm application, which would indicate disc run-out. A test drive should include several firm stops from around 30 mph to assess pedal feel and any judder or vibration through the steering wheel, as pitted rear discs on a torsion-beam rear axle can transmit noticeable feedback. The handbrake should also be evaluated on an incline, as rear caliper slider mechanisms can seize when discs have corroded unevenly, leading to uneven pad wear and reduced parking brake efficiency. The rear tyres should be inspected for both remaining tread depth and uneven shoulder wear, as the 2025 advisory specifically noted edge wear which can point to alignment issues, worn rear suspension bushes, or simply ageing rubber. With the tyres noted as borderline nearly twelve months ago, replacement is highly likely to have been carried out since, and confirmation of the brand, age, and matching fitment on both sides should be sought. Front brake pads, flagged as wearing thin in 2023, should also be checked for remaining material, and the front discs inspected for lipping and corrosion in line with the rear pattern. Beyond the documented items, a thorough underbody inspection for any developing corrosion around the rear axle, subframe mounting points, and brake pipe routing is advisable, particularly given the disc corrosion pattern already observed. Finally, listen for any clonks or knocks from the rear suspension over uneven surfaces, which could indicate worn trailing arm bushes commonly affected on vehicles of this age and mileage bracket.
