XYZ Racing Hollow Rear Brake Kit — Mercedes Benz ML 320 CDI 4MATIC W164 (2006-2011)

The W164 ML 320 CDI carries well over two tonnes on a 4MATIC driveline, and its torque-rich OM642 diesel encourages exactly the kind of duty, towing, loaded family motorway runs, long Alpine descents, that punishes a braking system. On a heavy all-wheel-drive SUV the rear axle does more of the retardation work than most owners assume, and the standard rear discs start to glaze and fade once the heat has nowhere left to go.

This XYZ Racing Rear Big Brake Kit for the Mercedes Benz ML 320 CDI 4MATIC W164 (2006-2011) targets that specific weakness: a larger two-piece floating disc paired with an uprated caliper, sized to absorb and release heat faster than the factory rear setup. Supplied as a matched pair of rear calipers and rear discs, it is a rear-axle upgrade aimed at owners who actually load the car, not a cosmetic dress-up part.

What this brake kit does for your 2006-2011 Mercedes Benz ML 320 CDI 4MATIC W164

The bigger swept area and two-piece floating disc give the rear axle more thermal headroom, so the pedal stays firm through repeated stops instead of going long when the discs heat-soak. On a two-tonne 4MATIC that translates to more confident, repeatable braking down a loaded descent or after a series of hard motorway stops. The increased rotor mass resists the fade that triggers ABS intervention earlier than you want it. With three pad compounds, Street, Sport and Racing, you can match the bite and heat range to how the W164 is actually used, from daily commuting, through harder fast-road and light-towing work, to heavily loaded towing. The uprated caliper also tightens initial response, so the brakes feel proportionate to the diesel’s mass rather than overwhelmed by it, keeping front-and-rear balance composed.

About the rear big brake kit

The kit centres on a larger-diameter rear disc using a two-piece floating construction that trims rotational mass while opening up airflow for quicker cooling, useful on a vehicle this heavy, where rear-brake temperature is the limiting factor; the ring can be drilled or slotted at the same price. It bolts to the W164 rear axle as a direct fitment and pairs the rotor with a matched performance caliper. The caliper is hollow-bodied as standard, with a Hollow Racing upgrade (no dust cover, rated to 1000C, two-year warranty) for hard track or heavy-duty work. Pad choice is left open across Street, Sport and Racing compounds so the system can be specified for road comfort, mixed road-and-load use, or sustained high-temperature work. Painted caliper colours are no-cost, Red, Yellow, Gold, Black or Anodized Black, with a Custom Color in any Pantone for GBP 150 more; premium polished-forged finishes (Titanium, Polished Gold, Polished Silver), candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) and two-tone or titanium centre bells let the visible hardware behind the wheel suit the car without changing the engineering underneath. The emphasis throughout is consistent rear-axle braking under heat, not headline figures.
