2004 Peugeot Boxer 2.0L Diesel · WD04 LDU

Recurring brake system issues define the mechanical history of this Peugeot Boxer, which successfully passed its most recent MOT on 8 July 2025 despite persistent warnings regarding component wear and fluid leaks. While the vehicle has maintained a general trend of passing its annual inspections, the record is punctuated by repeated instances of binding service brakes across multiple axles, culminating in a failure for an excessively binding rear brake in early 2024. The presence of both pitting on the front discs and a gearbox oil leak in the latest assessment indicates that while the vehicle remains roadworthy, it is currently experiencing degradation of critical mechanical interfaces that require ongoing monitoring. Accumulating only 18,502 miles over twenty-two years results in an exceptionally low annual average of approximately 841 miles. This pattern of infrequent use often leads to the premature seizure of mechanical components that rely on regular movement to remain free, such as brake calipers, handbrake cables, and sliding mechanisms. The history of binding brakes is a direct consequence of this limited usage profile, as the vehicle has likely spent extended periods stationary, allowing for the accumulation of surface corrosion on discs and the potential degradation of seals within the hydraulic system. Prospective buyers should prioritise a thorough evaluation of the braking system during a test drive, specifically looking for any signs of the vehicle pulling to one side under deceleration or a heavy, unresponsive brake pedal. Given the advisory regarding pitted front discs, listen for any grinding noises or vibrations transmitted through the steering wheel when braking from speed. It is also essential to verify that the handbrake releases fully without resistance, as the previous failure for a binding rear service brake suggests that the rear calipers or associated linkage mechanisms may be prone to sticking after the vehicle has been parked for a duration. Further inspection should focus on the gearbox oil leak noted in the 2025 test. Inspect the area beneath the transmission housing for fresh fluid spots after the vehicle has been parked, and pay close attention to the gear selection process during the test drive to ensure there is no stiffness, crunching, or hesitation when shifting. Because the vehicle has experienced multiple years of low-mileage operation, a physical check of the exposed suspension components and rubber bushes for signs of perishing or cracking is advisable, as these parts can harden and fail due to age rather than distance travelled.
