XYZ Racing Hollow Rear Brake Kit — Mercedes Benz ML 350 BLUETEC W166 (2011-2015)

The W166-generation ML 350 BlueTec asks a lot of its rear axle: the better part of 2.2 tonnes, a torque-rich OM642 V6 diesel, and the kind of laden motorway and towing miles that turn a long descent into a heat-soak problem. The XYZ Racing Rear Big Brake Kit for the Mercedes Benz ML 350 Bluetec W166 (2011-2015) goes after exactly that, adding thermal headroom and a firmer, more progressive rear pedal to a heavy 4MATIC SUV that spends its life working hard.

This is the rear half of the equation, supplied as a matched pair of rear calipers and rear discs, built to restore brake balance once the fronts have been uprated, or simply to give a standard car more resistance to fade. Three pad compounds, Street, Sport and Racing, cover everything from family duty to repeated hard stops without forcing one setup on every owner.

What this brake kit does for your 2011-2015 Mercedes Benz ML 350 Bluetec W166

On a vehicle this heavy, the gain you feel first is consistency. The rear kit adds heat capacity where the standard discs run out of it, long alpine descents, towing, or a string of heavy stops from motorway speed, so the pedal stays where you left it instead of going long. The Racing compound bites harder and tolerates more temperature for track or fast-road use, the Sport compound widens the heat range for spirited driving, while the Street pad keeps strong cold performance and lower dust for daily driving. Run it alongside a front upgrade and the W166 stops leaning entirely on its front axle, settling into a more planted, balanced stop with front-and-rear effort shared properly. A choice of caliper finishes means the hardware looks deliberate behind the factory or aftermarket wheels.

About the rear big brake kit

The kit sheds rotating and unsprung mass at the rear axle with a two-piece floating disc, where it counts on a two-tonne SUV; the ring can be specified drilled or slotted at the same price. It is a bolt-on caliper, disc and pad package sized for the W166’s rear hubs, designed to raise thermal capacity rather than chase a headline figure. 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 use. The three-stage pad choice is the heart of it: a Street compound for quiet, low-dust manners, a Sport compound that trades a little dust for sharper response and a wider heat range, and a Racing compound built for the temperatures that towing and track work generate. Painted caliper colours come at no cost in Red, Yellow, Gold, Black or Anodized Black; a Custom Color in any Pantone is GBP 150, and 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 are also available, so the visual upgrade matches the functional one. Everything is specified around the rear position, complementing a front big brake kit or standing on its own to firm up an under-braked back axle.
