2016 Peugeot 508 2.0L Diesel · NG65 CUH

A pattern of persistent rear brake disc wear has defined the roadworthiness record of this 2016 Peugeot 508, with pitted or scored rear discs flagged as a developing defect for three consecutive test cycles across 2024 and 2025, and once again appearing at the most recent assessment on 25 June 2026 where the vehicle passed. While the car has ultimately held a current pass at each annual inspection, the recurrence of the same advisory on both nearside and offside rear discs indicates progressive surface deterioration rather than a one-off issue. A closer look at the June 2026 visit also reveals a prior-day failure on 24 June 2026 involving a split offside outer drive shaft CV boot allowing ingress of dirt, alongside a malfunctioning tyre pressure monitoring system, both of which were evidently rectified for the pass the following day. The presence of a previous failure on the immediately preceding test, though subsequently resolved, underlines the need to verify the quality and durability of those repairs rather than simply accepting the pass certificate at face value. With 113,234 miles accumulated over approximately ten years, this 508 has covered around 11,300 miles annually, a broadly typical usage rate for its age that points to regular driving rather than long periods of inactivity or unusually high motorway mileage. The mileage progression across the recorded tests shows steady, incremental increases consistent with continuous use, which generally favours even wear of mechanical components and reduces the risk of seized fasteners, dried seals, or corroded brake components sometimes seen on low-mileage or stored vehicles. That said, the combined effect of consistent annual use and the recurring brake disc advisories confirms that the rear braking system has reached the stage where friction material and disc surface condition merit close physical inspection rather than assumption. Any prospective buyer should treat the rear braking system as the primary area for scrutiny, beginning with a physical check of both rear discs for lipping, visible ridges, and hot spots, as pitted surfaces progressively worsen under load and can ultimately compromise braking efficiency. The rear brake pads should be measured for remaining material thickness, and the calipers examined for binding or uneven slider operation that often accompanies neglected rear discs. A test drive should focus on any rear brake judder under firm pedal application, pulling to one side under braking, or a spongy pedal suggesting further hydraulic attention is required. Beyond the braking system, the offside driveshaft and CV boot replacement carried out between the 24 and 25 June 2026 tests warrants verification by inspecting the boot for fresh grease contamination around the joint and confirming the retaining clips are properly seated, as a poorly refitted boot will fail again rapidly. The tyre pressure monitoring system should be checked by ensuring all four sensors are functional and that the warning lamp extinguishes after inflation adjustments. On the road, listen for any clicking or knocking from the offside front under full lock which would indicate CV joint damage from contamination, and feel for any vibration through the steering wheel that might point to related imbalances. Finally, inspect the rear brake flexible hoses for cracking under load, and confirm the headlamp alignment is correct following the prior beam aim failure, as these represent the remaining recorded concerns from the vehicle's test history.
