2021 MG ZS Exclusive EV Electricity · JO63 LSN

Brake disc wear on the rear axle is the sole mechanical point flagged in the MOT history, with advisories on both nearside and off‑side rear discs recorded at the most recent test on 23 June 2026; otherwise the three‑year record shows clean passes and no failures, indicating a generally stable roadworthiness profile apart from the emerging brake‑disc condition. At 17 880 mi the MG ZS has averaged roughly 3 600 mi per annum since its 2021 registration, a mileage level that is low for a five‑year‑old vehicle. The low annual accumulation suggests limited use rather than prolonged periods of inactivity, as there are no gaps in the MOT schedule that would hint at the car being off the road for extended stretches. Light usage typically translates to slower wear on wear‑items such as tyres, suspension bushes and brake pads, but it also means that any wear that does appear – for example the rear disc scoring – may be more noticeable relative to the overall low mileage. When inspecting the rear brakes, feel for any pulsation or vibration in the pedal under moderate braking, listen for a high‑pitched squeal or grinding that could indicate surface irregularities, and check for uneven pedal travel that might betray differing disc thicknesses left‑right. A visual inspection through the wheel spokes should reveal any deep scoring, rust spots or excessive wear patterns; if the discs appear thin or heavily pitted, replacement will likely be required within the next few thousand miles to maintain safe stopping distances. Also verify that the caliper pistons move freely and that there is no leakage of brake fluid around the rear caliper pins, as disc wear can sometimes be accelerated by uneven pressure. Given the otherwise clean MOT record, the next priority is to address the rear disc condition before it progresses to a failure. Arrange a professional measurement of disc thickness and, if the minimum legal limit is approached, budget for disc resurfacing or replacement. While the EV powertrain itself shows no MOT‑related concerns, ensuring the braking system remains fully compliant will keep the vehicle road‑legal and safe for continued low‑mileage use.
