2022 MG ZS Exclusive VTI-Tech 1.5L Petrol · NV71 PRX

The vehicle remains roadworthy, but the MOT history reveals a persistent trend of deteriorating rear braking system components. In the most recent test on 15 December 2025 at 32,374 miles, the tester identified pitting and scoring on both rear brake discs alongside fluctuating performance on the nearside and offside rear service brakes. While the vehicle passed the test, the recurrence of these issues indicates that the rear braking components are experiencing accelerated wear or were not addressed during the previous interval. The mileage pattern is consistent with typical UK usage for a modern vehicle, averaging approximately 8,100 miles per year. Between the December 2024 test at 24,580 miles and the December 2025 test at 32,374 miles, the car covered 7,794 miles. This regularity suggests consistent use rather than long periods of standing, which likely explains the surface corrosion noted on the brake discs, as stationary vehicles often suffer surface oxidation on iron components. A buyer must conduct a thorough physical inspection of the rear brake assembly before proceeding with a purchase. The repeated reports of pitting and scoring suggest the rear discs are reaching the end of their functional life, or that the calipers are sticking slightly, causing uneven heat and wear. You should check for any vibration through the brake pedal during a test drive and inspect the thickness of the rear pads for uneven thinning. Given the fluctuating brake readings, a full replacement of the rear discs and pads is likely necessary to ensure consistent stopping performance and prevent further mechanical degradation.
