Caliper render for this kit:

Few Mercedes platforms ask as much of their rear brakes as the V-Class W447. Fill the cabin with seven passengers and their luggage, hitch a trailer, and the back axle is suddenly carrying the kind of load a saloon never sees, then asked to scrub it off on a long motorway descent. The XYZ Racing Hollow Rear Brake Kit for the Mercedes Benz V Class W447 (2014-2026) is built for exactly that duty cycle.
This is a rear big brake upgrade aimed at heat capacity and consistency under load, not headline lap times. A larger rotor and a stiffer caliper give the W447 more thermal mass to soak up repeated heavy stops, so pedal feel stays predictable when the van is working hardest.
What this brake kit does for your 2014-2026 Mercedes Benz V Class W447
On a vehicle this heavy, the gain you notice first is fade resistance. The hollow-vane disc sheds heat faster than the standard rear setup, keeping the pads inside their working temperature window during airport runs, alpine descents and towing. Pick the Racing pad compound for higher bite and a firmer initial response; the Sport compound trades a little of that for a wider heat range; the Street compound keeps things low-noise and low-dust for daily manners. A bigger rear rotor also sharpens brake balance, easing the front pads’ workload so the W447 pulls up squarer under hard braking with a full cabin. The pedal that greets you on the tenth stop feels like the one you had on the first.
About the XYZ Racing Hollow Rear Brake Kit
The kit pairs an XYZ Racing rear caliper with the brand’s two-piece floating, hollow-vane disc. The hollow-vane construction takes mass out of the disc to aid cooling and trim unsprung weight, while the increased swept area raises the brakes’ overall thermal capacity, the property that matters most on a two-tonne-plus people carrier. The caliper body is hollow as standard, with an optional Hollow Racing upgrade for serious track use, rated to 1000C with no dust cover and a two-year warranty. Three pad compounds are offered so you can match the kit to how the van is actually used: Street for ordinary road duty, Sport for a more positive pedal with manageable dust and a wider heat range, and Racing for the strongest bite when the W447 is run loaded or hard. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable, and calipers are finished at no extra cost in Red, Yellow, Gold, Black or Anodized Black, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or a Custom Pantone for 150 pounds, so the upgrade can sit on show behind the wheels or stay discreet. Everything is configured to suit the rear axle of this specific chassis.

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 330–356mm (rear). 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.
