Caliper render for this kit:

The X247 GLB 250 sits at a curious intersection in Mercedes’ range: a 2.0T compact crossover with genuine family-car credentials, seven seats, substantial ground clearance, and a kerb weight above 1,700kg in most configurations, that owners nonetheless press hard on fast A-roads and motorway runs. At that mass, the front brakes carry more thermal responsibility than they would in the lighter A-Class or CLA sharing the same MFA2 architecture, and the standard setup leaves less headroom for the heat that accumulates under sustained high-speed braking.
The XYZ Racing front brake kit for the Mercedes Benz GLB 250 X247 replaces the front hardware with a pair of uprated discs and calipers and a three-tier compound system. The result is a setup scaled to the GLB’s actual weight and driving demands rather than the lighter-platform assumptions the factory brakes were sized for.
What this brake kit does for your 2019-2026 Mercedes Benz GLB 250 X247
Carrying the crossover body’s extra mass into a braking zone concentrates more thermal energy at the front axle than GLB 250 owners used to lighter MFA2 variants might anticipate. Two-piece floating discs dissipate that heat more efficiently than their OEM equivalents through their hollow-vane geometry, maintaining consistent pedal response through successive hard stops rather than allowing fade to develop, while the floating ring expands without warping and reduced rotating mass aids response. Three pad compounds, Street, Sport, and Racing, address the GLB 250’s spread of real uses: Street delivers quiet, low-dust bite for road driving without the sharp initial response that makes stop-start traffic uncomfortable; Sport extends the working temperature range for track mornings and spirited fast-road driving; Racing targets sustained circuit use where compound stability at elevated temperatures is the priority. Discs are offered drilled or slotted at the same price. Caliper colours, Red, Yellow, Gold, Black, or Anodized Black at no extra cost, with a custom Pantone match and premium polished-forged or candy finishes, let the front hardware complement the wheel design rather than sit as a visual afterthought.
About the front brake kit
XYZ Racing builds this kit around a two-piece floating disc whose internal vane geometry promotes airflow through the disc body, improving thermal management under the sustained loads heavier crossover platforms generate. Unlike a single-compound setup, the three-tier range, Street, Sport, and Racing, stays functional and predictable across a wide operating range, so the same kit that handles daily errands confidently can switch to a harder compound for a track session without a full hardware replacement. The caliper is a hollow-body forging as standard, with an optional Hollow Racing caliper, no dust cover, rated to 1000C, two-year warranty, for harder use. Caliper finish choices acknowledge that brake hardware is now routinely visible through modern wheel designs: the colour is structural to the car’s finished look, not incidental. Braided lines firm the pedal, and centre bell upgrades in five anodized colours or titanium are selectable at checkout. The kit covers the X247 front axle specifically, from the GLB 250’s 2019 introduction through to the current 2026 model year.
Fitment for the Mercedes Benz GLB 250 X247 (2019-2026)
This kit is built to the X247 front-axle specification and covers the Mercedes Benz GLB 250 across the full production run from 2019 to 2026. Buyers should confirm their existing disc diameter against the supplied specification before ordering; the chassis code X247 and production year are the key compatibility checks.

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.
