Caliper render for this kit:
The Staria US4 is a big, honest workhorse, and big, honest workhorses need to stop as reliably as they go. Hyundai’s fourth-generation MPV brought a platform capable of carrying nine passengers or a substantial commercial payload, and physics is unforgiving about what that means for the front axle: the majority of deceleration force lands there, consistently, whether the van is empty or loaded to the roof. Under repeated braking cycles, think a fully booked airport run through stop-start motorway traffic, or a descent with a full complement of passengers, the standard front brake specification runs short of thermal headroom.
This XYZ Racing front big brake kit addresses that headroom directly. It is a front-axle kit, a matched left and right pair of calipers and two-piece floating discs. Three pad compounds let owners calibrate stopping feel to actual use, Street, Sport or Racing, and caliper colour is chosen when you order so the installation integrates cleanly with fleet liveries or conversion specifications.
What this brake kit does for your 2021-2026 Hyundai Staria US4
Front-axle bias is a physical fact for the US4: when a loaded MPV of this mass sheds speed, the forward weight transfer intensifies the load on the front pads and discs with each application. The hollow-vane disc in this kit routes air through its internal structure to move heat away from the contact face faster than a conventional solid disc, slowing the temperature rise that progressively softens pedal feel, and the two-piece floating design keeps the iron ring flat as it heats so the pedal stays consistent. Selecting Sport or Racing extends the effective operating temperature window further, so stopping distance under a second or third consecutive hard application does not grow in a way that catches a driver out. Included caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a Custom Color in any Pantone available to match a conversion or livery without compromising function.
About the Hollow Front Brake Kit
Heat management is the deciding factor on a vehicle of the Staria’s mass: it is the difference between a brake that holds its pedal feel through a loaded descent and one that returns a lengthening, softening stop after the second or third hard application. The caliper is a hollow-body forging as standard, light but stiff, with an optional Hollow Racing upgrade for the most demanding duty that drops the dust cover, is rated to 1000C and carries a two-year warranty. Discs are available drilled or slotted at the same price, both running the hollow-vane internal structure. Three compounds cover the realistic spread: Street for everyday mixed-duty operation, Sport for operators wanting stronger initial bite across a demanding duty cycle, and Racing for those who genuinely need the extended temperature ceiling on high-frequency commercial runs, marshalling support or track-adjacent use. Beyond the no-cost painted colours there are premium polished-forged Titanium, Polished Gold and Polished Silver, and candy Teal, Blue, Red and Orange, plus two-tone or titanium centre bell upgrades, all selectable at checkout. The front-only fitment targets the axle where thermal loading on the US4 platform is greatest.
Fitment for the Hyundai Staria US4 (2021-2026)
This kit is built for the Hyundai Staria US4 generation, covering the front axle position across 2021 to 2026 model years. The US4 designation spans both passenger and commercial configurations; confirm your specific variant and any all-wheel-drive specification against the product options before ordering, as front hub details can vary across the Staria’s model grades.

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.
