2012 Audi A1 1.4L Petrol · KX12 UGZ

Brake wear on the rear axle dominates the MOT record, with successive advisories for both rear brake discs and pads appearing in the last two tests. The 2026‑09‑01 MOT was passed, yet it highlighted that the nearside and off‑side rear discs are worn, pitted or scored and that the corresponding pads are thin, echoing the rear‑disc advisory from the 2025‑08‑29 test. Apart from a single tyre‑condition advisory in 2024, the vehicle has otherwise cleared its examinations without failures, indicating a consistent, though not worsening, pattern of rear‑brake wear that should be addressed promptly. At 84,357 mi the car averages roughly 6,000 mi per year over its 14‑year lifespan, a mileage rate that sits comfortably within typical usage for a small hatchback. The MOT history shows no gaps in testing, suggesting the odometer reading has been regularly recorded. This moderate annual accumulation means that wear on consumables such as brakes, tyres and suspension components will be in line with normal ageing, rather than accelerated by high‑mileage stress. When inspecting the rear braking system, verify disc thickness against the manufacturer’s minimum specification and look for surface scoring that could cause vibration when braking. On a drive, listen for a high‑pitched squeal or feel a pulsating pedal, both of which may indicate that the thin pads are nearing the end of their service life or that the discs are close to the wear limit. Check that the caliper pistons move freely and that there is no uneven pad wear that could suggest a sticking caliper or warped disc. If the discs are within tolerance but the pads are thin, replacement of both pads and discs together is advisable to avoid uneven braking performance. The tyre advisory from the 2024 MOT points to early cracking or perishing on all four wheels, a condition that typically progresses quickly once it appears. Examine the sidewalls for any visible cracks, bulges or loss of rigidity, and measure tread depth to confirm it exceeds the legal minimum of 1.6 mm across the tyre width. During a test drive, note any vibration or pulling that could indicate uneven tyre wear or structural degradation. Given the age of the tyres and the advisory, budgeting for a full set of replacements in the near term would be prudent to maintain safe handling and compliance with future MOT requirements.
