Caliper render for this kit:

The Mazda CX-9 4WD (TB) MK1 is a three-row, near-two-tonne SUV built on Ford’s CD3 platform, and all of that mass has to be hauled down every time you brake hard from motorway speed with seven aboard or a trailer on the hitch. The XYZ Racing Hollow Rear Brake Kit for the CX-9 targets the rear axle’s share of that work, the exact place where the standard discs heat-soak under repeated heavy stops and the pedal starts to lengthen.
This is a rear-specific upgrade for the CX-9 4WD (TB), a pair of left and right rear calipers with matched discs whose hollow-vane construction moves heat away from the friction surface faster than the solid OE items. Matched to a pad compound chosen for how you actually use the car, it gives the back axle the thermal headroom to brake the same way on the tenth stop as it did on the first.
What this brake kit does for your 2006-2015 Mazda CX-9 4WD (TB) MK1
On a heavy, front-biased AWD SUV like the CX-9, the rear brakes are easy to overlook until they cook on a long Alpine descent or a loaded tow. This kit restores rear-axle braking balance so the nose does less of the work alone, which steadies the car under hard, late braking. The hollow disc design resists the fade you feel after a sequence of stops, and the choice of Street, Sport or Racing pad compound lets you set bite and temperature range to your driving. Behind the wheels, the included painted caliper finish (Red, Yellow, Gold, Black or Anodized Black), a Custom Color, or the premium polished and candy ranges give the back end a cleaner look through the spokes.
About the Hollow Rear Brake Kit
The Hollow Rear Brake Kit is XYZ Racing’s rear-axle braking package for heavier platforms, named for its hollow-vane disc construction that increases the surface area working to dissipate heat. Lower operating temperatures mean the pad and disc stay inside their effective window for longer, which is what keeps stopping distances consistent under repeated load. The discs are two-piece floating units offered drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. The kit ships with a three-tier pad compound choice: a Street compound for everyday road use, a Sport compound for harder fast-road driving, and a Racing compound for track and competition heat. The hollow-body caliper is standard, with an optional Hollow Racing upgrade rated to 1000C, no dust cover and a two-year warranty for serious track use. Caliper bodies are offered in the included painted colours through to a custom Pantone, so the kit can be specified to suit the build rather than the parts bin. It is engineered as a direct rear fitment for the CX-9, replacing the OE rear setup rather than supplementing it.

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.
