Caliper render for this kit:

The Mazda Millenia carries the bulk of its mass over the front axle, the legacy of a front-wheel-drive executive saloon built around a transverse V6, including the unusual Miller-cycle supercharged unit that made the Millenia S such an oddity in the 1990s. That front bias leaves the standard rear brakes under-worked and quick to lose feel once you start braking hard and often, whether on a spirited B-road or a track day in a car few people expect to see there.
This XYZ Racing Hollow Rear Brake Kit addresses the rear axle specifically, a pair of left and right rear calipers with matched discs that restore balance to a chassis tuned for refinement rather than repeat heavy stops. It is a considered upgrade for owners keeping one of these increasingly rare saloons sharp in 2026.
What this brake kit does for your 1992-2003 Mazda Millenia
On a nose-heavy saloon like the Millenia, a stronger rear setup does more than add clamping force. It gives the rear axle a larger thermal reserve, so pedal feel stays consistent as the discs heat up instead of going long and vague after a few hard applications. With three pad compound options, Street, Sport and Racing, you can match the rear bite to how the car is used, from comfortable road driving through quicker fast-road work to harder track sessions. The result is a more planted, predictable car under braking, with the rear contributing properly to deceleration rather than trailing behind the front.
About the Hollow rear brake kit
The Hollow rear kit is XYZ Racing’s bolt-on rear axle brake package for the Millenia, pairing an upgraded hollow-body caliper and two-piece floating disc with a choice of friction material. The hollow disc construction sheds heat and reduces rotating mass compared with a heavier solid casting, which helps the brakes recover between stops. Discs are offered drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. Pad compounds run from a Street option through a higher-bite Sport pad to a full Racing compound for cars that see circuit use. The hollow-body caliper is standard, with an optional Hollow Racing upgrade rated to 1000C, no dust cover and a two-year warranty for hard track use. Calipers are finished in a choice of included painted colours (Red, Yellow, Gold, Black and Anodized Black), a Custom Color matched to any Pantone, or the premium polished and candy ranges, so the kit suits both a discreet factory look and a more obvious modified build behind open-spoke wheels.
Fitment for the Mazda Millenia (1992-2003)
This kit is matched to the rear axle of the Mazda Millenia across the full 1992 to 2003 production run and ships as a matched pair of rear calipers and discs. It is a rear-position kit, so it pairs naturally with a front upgrade or works as a standalone fix for owners who feel the rear axle is the weak link. Confirm your exact build year 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 330–356mm (rear). 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.
