Caliper render for this kit:

The W164 ML 320 Bluetec weighs in at roughly 2,150kg, and that 3.0-litre V6 diesel delivers 510Nm from well under 2,000rpm. Those numbers have a direct consequence for the front axle: arriving at a tight hairpin after a fast motorway run or a loaded Alpine descent, the standard front brake package is working at the outer edge of what it was designed to handle. This kit replaces that limiting factor.
The XYZ Racing front big brake kit adds thermal capacity and stopping confidence to the W164, not as a track-only conversion but as a sensible hardware upgrade for a heavy diesel SUV that regularly operates at its braking limits on real roads. It is a matched pair of left and right front calipers and two-piece floating discs, sized to the W164 front hub.
What this brake kit does for your 2006-2011 Mercedes Benz ML 320 BLUETEC W164
The two-piece floating disc at the core of this kit is the reason the upgrade matters. On a vehicle of the ML’s mass, repeated hard stops, whether descending a mountain pass with a caravan behind or braking repeatedly from motorway speed, generate heat that conventional discs struggle to shed cleanly. The floating bell lets the friction ring expand without distorting, the hollow-vane construction increases airflow through the disc, and the reduced rotating mass sharpens the pedal, keeping temperatures in range and reducing fade risk under sustained use.
The three pad compounds let you match the friction material to how the ML 320 actually gets used. Street is the quiet, low-dust road default for mixed driving with occasional loaded descents; Sport raises bite and heat range for harder fast-road work; Racing is the track compound for drivers braking hard from high speed without a cool-down. Disc faces are available drilled or slotted at the same price, presenting through the W164’s generous wheel apertures as subtle or as deliberate as the build requires.
About the Front Brake Kit
This kit takes a different approach to heat management than the uprated solid-disc kits that dominate the aftermarket. The two-piece floating, hollow-vane rotor sheds thermal load faster under the kind of sustained braking that an SUV of this weight generates routinely. The front-fitment focus reflects where the W164’s braking load actually concentrates: 4MATIC sends drive to all four wheels, but with a heavy diesel engine sitting ahead of the front axle, the front discs carry the harder work under emergency stops and prolonged mountain descents. The caliper is hollow-bodied as standard, with an optional Hollow Racing upgrade for hard track use that deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Braided lines firm the pedal, and centre bells can be upgraded to two-tone anodizing in five colours or titanium at checkout. Included painted caliper colours are Red, Yellow, Gold, Black, and Anodized Black at no extra cost, with a Custom Color in any Pantone for an additional 150 pounds, alongside premium polished-forged and candy finishes.
Fitment for the Mercedes Benz ML 320 BLUETEC W164 (2006-2011)
This kit is confirmed for the Mercedes Benz ML 320 Bluetec on the W164 chassis, covering the full 2006 to 2011 production span and supplied as a left-and-right front pair. The front-axle application addresses the W164’s primary braking load point directly. If you are running non-standard wheels, verify caliper clearance before ordering, particularly if you have moved to smaller-than-OEM wheel diameters.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).


Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
