2017 Land Rover Discovery 3.0L Diesel · JO13 JJL

Brake wear was the only mechanical issue flagged in the MOT record, appearing as front and rear disc wear advisories and thin rear pads in the July 2022 test; every subsequent inspection in 2023, 2024 and the September 2025 pass shows no further brake defects, suggesting the discs and pads have likely been replaced or resurfaced since that advisory, while the 2025 failure relates solely to a non‑conforming registration plate and does not affect roadworthiness. At 111,832 mi the Discovery averages roughly 12,400 mi per year, a mileage level that exceeds typical private‑use figures and points to substantial wear on consumable components such as tyres, brakes, suspension bushings and drivetrain joints. The MOT history shows no gaps longer than twelve months, indicating the vehicle has been regularly tested and, by implication, regularly driven; the relatively high annual accumulation means that parts subject to wear should be inspected for fatigue or thinning beyond the standard service intervals. When evaluating the brakes, verify disc thickness on all four wheels with a micrometer or calibrated gauge, ensuring they remain above the minimum legal limit and that the surface is free of scoring or cracks. During a low‑speed test drive, listen for any high‑pitched squeal that could indicate pad wear, feel for pulsation or shudder through the pedal that may reveal warped discs, and check that the vehicle pulls evenly when braking in a straight line, which would highlight uneven pad or disc wear. Also inspect the caliper mounting bolts and brake hose condition for signs of corrosion or leakage, as these can develop over time even after disc replacement. Finally, confirm that the registration plate now complies with the required specifications to avoid future statutory failures, and conduct a comprehensive visual and functional check of the suspension components—particularly the control arm bushings and shock absorbers—looking for excessive play, leaking oil or cracked mounts, as the high mileage can accelerate wear in these areas. A short road‑test should include a sweep over a speed bump to feel for any knocking or binding in the suspension, and a steady‑state high‑speed run to ensure steering remains stable and there is no unusual vibration that could indicate wheel‑bearing or drivetrain deterioration.
