2020 Mercedes-Benz A 1.5L Diesel · JD02 CAL

The most recent MOT on 3 September 2025 was a pass, but it highlighted two issues: the off‑side front tyre shows slight damage/cracking and the front and rear brake discs are all described as “worn, pitted or scored, but not seriously weakened”. These brake‑disc warnings recur from the 27 August 2024 test, where every disc (front and rear) was flagged as similarly worn, and a “front service brake fluctuating, but not excessively” note was added. The only outright failure in the record was a rear‑brake‑pad wear warning in March 2023, which has since been addressed, but the pattern of disc wear has persisted. This suggests the brake wear is stable rather than improving; the discs are approaching the end of their service life and will likely need replacement soon. At 71,858 mi for a six‑year‑old 2020 Mercedes‑Benz A, the mileage averages about 12 000 mi per year – essentially typical for a vehicle of this age. It does not point to excessive hard use, but the consistent brake‑disc wear could indicate a driving style that favours frequent braking or a lack of recent disc replacement. What to check first: - Inspect all four brake discs for depth and surface condition; confirm whether they are still within legal limits and consider budgeting for replacement. - Examine the front tyre for cracks, sidewall damage, and tread depth; replace if any signs of deterioration are evident. - Test the service brake for consistent pedal feel and ensure there is no pulsation or pull, which could indicate uneven disc wear or hydraulic issues. - Look for any unusual noises or vibrations when braking, and have a mechanic check the brake pads and calipers for wear or sticking.
