Fits Mercedes Benz S CLASS X222 MAYBACH (2015-2026)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

380 mm

Kerbside, the X222 Maybach hides its mass with the same ease it hides its length. Stamp the brake pedal from a motorway cruise with the rear seats occupied and the back axle of a two-tonne-plus limousine suddenly has real work to do, and on the standard setup that work shows up as heat. The XYZ Racing Hollow Rear Brake Kit goes after exactly that part of the equation, giving the rear of the Mercedes Benz S Class X222 Maybach the thermal headroom to take repeated heavy stops without the pedal travelling long.

This is a rear big brake kit built for a car that values composure over lap times. The two-piece floating, hollow-vane rotor sheds heat and trims rotating mass at the rear axle, so braking response stays consistent whether you are trimming speed on a long descent or settling the car down from an unhurried autobahn pace.

What this rear brake kit does for your 2015-2026 Mercedes Benz S Class X222 Maybach

The first thing you feel is repeatability: a heavy luxury saloon that pulls up the same on the tenth stop as it did on the first. The hollow-vane rotor cuts unsprung and rotating mass at the rear, which the air suspension and the ride quietly appreciate on a car this heavy. Three pad compound choices let you set the character: Street for refined, near-silent road use, Sport for a firmer initial bite and wider heat range, and Racing for the hardest, hottest stops. And with caliper finishes running from the five no-cost colours through premium polished-forged and candy options, the upgrade reads as deliberately as it stops.

About the Hollow rear brake kit

The Hollow rear brake kit replaces the standard rear-axle setup with an uprated two-piece floating rotor and caliper sized for the X222’s considerable weight. The defining feature is the hollow-vane rotor construction, which reduces disc mass and improves the rate at which heat is carried away from the friction surface, the single biggest factor in resisting fade on a heavy car. 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. Pad compound is configurable across Street, Sport and Racing options, so the same hardware can be tuned for quiet chauffeur duty or genuinely hard driving. Discs are drilled or slotted at the same price, with two-tone anodized or titanium centre bells selectable. Caliper finish is offered 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 to match the car. Everything here is aimed at controlled, fade-resistant rear braking rather than outright track lap times, which suits the Maybach’s brief precisely.

Fitment for the Mercedes Benz S Class X222 Maybach (2015-2026)

This kit is specified for the X222 Maybach long-wheelbase S Class across the 2015 to 2026 model span, fitted at the rear axle. Confirm your exact chassis code and model year before ordering so the rear-axle hardware matches your car. Pair it with the matching front kit for a balanced front-and-rear package.

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.
