Fits Mercedes Benz B CLASS W246 4 (2012-2018)

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.

XYZ Racing Hollow Front Brake Kit — Mercedes Benz B CLASS W246 4 (2012-2018) — 356 mm
356 mm

On the MFA-platform W246, both traction and primary braking fall to the same pair of corners, the arrangement of transverse front-wheel drive concentrating two demanding jobs on discs that were factory-sized for the standard engine tune. Owners who have remapped a B 200 or B 250, or who simply push the car on track days or demanding B-roads, will find the stock front setup starting to feel thin under repeated hard stops before anything else on the car shows strain. The XYZ Racing front brake kit addresses that gap with a matched pair of forged front calipers, two-piece floating discs, and a choice of pad compound from quiet daily use through to full Racing spec.

Painted caliper colours, Red, Yellow, Gold, Black, and Anodized Black at no extra cost, make a genuine visual statement on the W246, where open-spoke alloy designs leave the front calipers clearly visible. This is a kit that earns its presence on both counts.

What this brake kit does for your 2012-2018 Mercedes Benz B CLASS W246 4

Larger front brakes increase the mechanical leverage on the W246’s primary braking circuit, shortening stopping distances and firming the pedal response from the first press, differences that show up immediately in the 80-30 mph braking zones where the front axle loads up under deceleration on a front-drive car. The two-piece floating discs use internal vanes to pull airflow through the disc, drawing heat away from the friction surfaces faster than a solid unit, while the floating ring expands on its alloy bell without coning, reducing the fade and judder that build under repeated hard stops. Specifying a Sport or Racing compound raises the temperature ceiling further, extending viable use into track-day sessions for a B 250 or a tuned B 200, while Street stays quiet and low-dust for the commute. Braided lines firm the pedal, and all three compounds run the same caliper and disc, so switching compound later is a pad change only.

About the Hollow Front Brake Kit

The kit is built around a two-piece floating iron disc in which internal vanes separate the two friction rings, channelling airflow through the disc to accelerate heat dissipation, with the friction ring floating on an alloy bell to maintain consistent contact across a wider operating range than a solid disc allows. The caliper is a hollow-body forging as standard, and for sustained high-temperature work an optional Hollow Racing upgrade deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Pad compound is configured when you order: Street covers everyday B Class driving without fuss; Sport suits spirited fast-road use and occasional track sessions; Racing is specified for sustained high-temperature braking. Caliper finish runs five no-cost colours, Red, Yellow, Gold, Black, and Anodized Black, with a custom Pantone match for £150, premium polished-forged finishes in Titanium, Polished Gold, and Polished Silver, and candy finishes in Teal, Blue, Red, and Orange. Discs come drilled or slotted at the same price, and centre bells can be specified two-tone or titanium. This is a front-axle fitment, targeting the circuit that carries the majority of the W246’s braking load.

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.
