Fits Toyota ALPHARD IV (AH40) 4WD (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.

Painted — includedTell us the exact Pantone (PMS) code you want the calipers painted.Polished forgedCandy
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 — Toyota ALPHARD IV (AH40) 4WD (2023-2026) — 330 mm
330 mm

The AH40 Alphard’s 4WD drivetrain adds meaningful mass over the two-wheel-drive variant, and Toyota’s factory braking package is calibrated for the composed, unhurried stops that suit a premium MPV in daily use. Push an Alphard harder, down a mountain pass, across a motorway junction at pace, or simply with seven seats filled and luggage loaded, and the gap between what’s fitted and what’s needed shows up in the pedal and in the heat. The XYZ Racing Hollow Front Brake Kit closes that gap.

Three pad compounds let you calibrate the setup to how this Alphard actually lives. Street is the quiet, low-dust default that suits the majority of owners who want a clean, refined road brake. Sport adds bite and a wider heat range for those leaning on the van harder, and Racing is the dedicated track compound for the most demanding use.

What this brake kit does for your 2023-2026 Toyota ALPHARD IV (AH40) 4WD

The AH40 platform is notably heavier than its predecessor, and the 4WD system loads the front axle further still. Two-piece floating discs reduce rotating and unsprung mass at the front axle, which benefits both stopping distance and the way the van settles after a braking event. With the stock setup, repeated hard stops build heat in the system faster than a vehicle of this size would typically encounter; the upgraded kit provides meaningful additional thermal headroom when the Alphard is worked harder than Toyota intended. Caliper colour matters here too, because the AH40’s factory wheel gaps are substantial enough to make the hardware visible, so the installation reads as intentional through the spokes.

About the Hollow Front Brake Kit

XYZ Racing’s two-piece floating disc construction addresses the primary weakness of conventional cast-iron discs on heavier platforms: heat retention. The disc and bell are separate components, which lets the friction ring expand cleanly under temperature and keeps disc temperatures lower across repeated stops, reducing fade risk and extending pad life under sustained load. The caliper is hollow-bodied as standard to keep weight down, and braided lines are part of the kit for a firmer pedal. Three compounds cover the duty cycle: Street for refinement and longevity on UK roads, Sport for more bite and a higher heat range, and Racing for the circuit. Painted caliper colours included at no extra cost are Red, Yellow, Gold, Black, and Anodized Black; a Custom Color in any Pantone is £150, with premium polished-forged (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange) also offered.

Fitment for the Toyota ALPHARD IV (AH40) 4WD (2023-2026)

This kit is supplied specifically for the Toyota Alphard IV, chassis code AH40, in 4WD specification, covering 2023 to 2026 model years. Confirm your variant is the 4WD model before ordering, as front-axle geometry and hub specifications differ from the two-wheel-drive AH40.

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.
