Fits Scion XB (2007-2015)

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 — Scion XB (2007-2015) — 330 mm
330 mm

The AN20-generation XB is heavier than its boxy dimensions suggest. The 2AZ-FE sits ahead of the front axle, front-wheel drive asks that same axle to manage braking and steering at once, and the standard stoppers were specced for sensible rather than spirited use. Push the XB harder than its OEM brief intended and the factory brakes run out of composure before the chassis does.

This XYZ Racing front big brake kit addresses that directly. It is a matched pair of front calipers and two-piece floating front discs, and it covers the front axle only.

What this brake kit does for your 2007-2015 Scion XB

Front-biased weight on a front-drive platform means the front axle handles the majority of each deceleration event. A bigger disc spreads heat across more material, and a larger caliper generates more clamping force from a given pedal input. On a car regularly driven beyond its original design brief, the practical effects are later fade onset, more consistent pedal feel through the middle and end of a braking zone, and greater confidence carrying speed into a corner without the progressive softening that comes from undersized or heat-soaked factory discs. The two-piece floating discs also cut rotating and unsprung mass at the front, which sharpens turn-in on a tall, nose-heavy body.

Three pad compounds mean the same kit works across very different use patterns without a hardware swap. Street is the quiet, low-dust default for mixed urban and road driving. Sport firms up the pedal and sharpens bite for keener fast-road use. Racing is the dedicated circuit compound built for the sustained temperatures only repeated track work generates. Included caliper colours are Red, Yellow, Gold, Black, and Anodized Black at no extra cost, with any Pantone available as a Custom Color, plus premium polished-forged and candy finishes for owners running open-spoke wheels who want the hardware to show.

About the Hollow front brake kit

The caliper is hollow-bodied as standard, a forged construction that keeps mass low without losing rigidity, and serious track users can specify the optional Hollow Racing caliper, which deletes the dust cover, is rated to 1000C, and carries a two-year warranty. Discs are available drilled or slotted at the same price, so the choice comes down to feel and looks, and the centre bells can be upgraded to a two-tone anodized finish in five colours or to titanium, all selectable when you order. On a front-driven application like the XB, where weight transfer under braking loads the front pads hardest and the heat cycles are most demanding, the extra swept area and clamping make a measurable difference at the axle that needs it.

Fitment for the Scion XB (2007-2015)

This kit covers the full second-generation Scion XB production run from 2007 through 2015 on the AN20/AN25 platform. The XB ran the 2.4-litre 2AZ-FE throughout that period with MacPherson strut front suspension, the configuration this front-axle kit is specified for. Confirm your build year falls within the 2007-2015 span before ordering.

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.
