Fits Kia SORENTO (MQ4) (2023-2026)

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.

XYZ Racing Hollow Front Brake Kit — Kia SORENTO (MQ4) (2023-2026) — 380 mm
380 mm

At kerb weights approaching two tonnes in Plug-In Hybrid trim, the Sorento MQ4 places serious thermal demands on its front brakes that the factory calibration was not always conceived to accommodate. The PHEV variant carries considerably more mass than the equivalent combustion model, dead weight the hydraulic front brakes must shed on a sustained descent or in an emergency stop once the regenerative system has given what it can.

This XYZ Racing front big brake kit replaces the front discs and calipers on the Kia Sorento (MQ4) 2023-2026 with a setup designed to handle heat more effectively under load. Three pad compounds let the buyer configure the system to match actual use rather than a factory assumption about how the car would be driven.

What this brake kit does for your 2023-2026 Kia SORENTO (MQ4)

The two-piece floating disc is the functional core of the upgrade, improving heat rejection across the swept surface, relevant on a platform this heavy when the brakes are working repeatedly: prolonged descents, spirited driving with a trailer on the back, or frequent hard stops in a 1,900 kg-plus car. The hollow-vane rotor accelerates heat dissipation, the floating bell keeps it flat as it heats, and braided lines firm the pedal for predictable feel under load.

Pad compound shapes how the system behaves across temperature. Street is the quiet, low-dust default for moderate daily use. Sport operates across a wider range, built for the driver who mixes everyday mileage with harder use and wants fade resistance without committing to a track-only setup. Racing holds up at the sustained temperatures that glaze conventional friction material: full circuit sessions, repeated high-speed stops, mountain runs with a caravan in tow. You select the compound when you order.

About the front big brake kit

The kit pairs a hollow-body forged caliper as standard with a two-piece floating disc engineered to shift heat out of the swept surface more efficiently than a standard ventilated disc. Discs are offered drilled or slotted at the same price, and centre bell upgrades come as two-tone anodizing in five colours, or titanium, selectable at checkout.

Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. A Custom Color in any Pantone is £150. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, with a premium candy range of Candy Teal, Candy Blue, Candy Red and Candy Orange, so the installation reads as deliberate rather than functional-only. For the most punishing use, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C and carries a two-year warranty. This is a front-axle kit and works in conjunction with the MQ4’s existing rear brakes.

Fitment for the Kia SORENTO (MQ4) (2023-2026)

This kit is built for the Kia Sorento on the MQ4 platform, covering model years 2023 to 2026, spanning the post-facelift continuation through the end of the generation. Fitment covers petrol, mild hybrid and Plug-In Hybrid powertrain configurations. Confirm your specific model year and trim level before ordering to ensure the correct caliper bracket and disc specification are supplied.

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.
