2012 Renault Master 2.3L Diesel · MJ62 HTX

A pattern of brake‑system deficiencies underpins this Master’s MOT record, with multiple years showing excessive service‑brake binding on both front and rear axles and recurring corrosion of the brake pipes. The 2025‑10‑21 test finally returned a pass, but only after an advisory for slight play in the nearside front anti‑roll‑bar linkage ball joint and a minor registration‑plate lamp fault, indicating that the most serious brake failures recorded in 2023 have not resurfaced yet, though the underlying corrosion warnings remain. The overall trend moves from dangerous failures in 2023 to a clean pass in 2025, yet the persistence of advisories suggests that the brake system has not been fully rectified. At 190,055 mi over 14 years the vehicle averages roughly 13,600 mi per annum, well above the typical usage for a light commercial van of this age. Such mileage accelerates wear on consumables – brake pads, discs, hoses and suspension components – and amplifies the impact of any corrosion that may have developed on the chassis or brake pipe fittings. The MOT history shows no long gaps in testing, implying continuous road use rather than prolonged storage, which further supports the expectation of progressive component fatigue. When inspecting the brakes, feel for any pedal pulsation, sponginess or a high‑pitched squeal that could indicate lingering binding or uneven pad wear. Verify that the pedal returns smoothly and that braking force is balanced left‑to‑right; any pull to one side may point to a still‑corroded pipe or a compromised hose. Examine the visible brake pipes for surface rust, greased deposits or signs of leakage, and confirm that the front brake hose is correctly routed and not twisted. A functional parking brake should hold the vehicle stationary on a gentle incline with at least 50 % efficiency – a test that should be repeated on the road, given the dangerous failure recorded in August 2023. The anti‑roll‑bar linkage ball joint on the nearside front should be checked for play by applying a firm push/pull on the bar while the vehicle is lifted; any clunk or excessive movement warrants replacement. Inspect the steering rack gaiter for signs of wear or missing material, as its absence in 2023 could permit dirt ingress and affect rack integrity; feel for any looseness or binding in the steering column during low‑speed manoeuvres. Finally, confirm that the off‑side headlamp aim is within legal limits, that both wiper blades make full contact without skipping, and that all side‑marker lamps illuminate, as these minor items were flagged in recent advisories and are easily verified before purchase.
