Fits Toyota PRIUS (XW30) (2009-2015)

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 Rear Brake Kit — Toyota PRIUS (XW30) (2009-2015) — 380 mm
380 mm

The XW30 Prius does most of its slowing on the electric motor, feeding energy back to the battery and leaving the mechanical rear brakes to idle. On a 2009-2015 car that under-use has a cost: glazed friction surfaces, sticking slide pins, and rear calipers that corrode and seize long before the rest of the car is tired. The XYZ Racing Hollow Rear Brake Kit swaps that neglected hardware for fresh, larger components that are actually built to be used.

This is the rear-axle half of a brake upgrade for the Toyota Prius (XW30), supplied as a left-and-right pair, aimed at owners running serious mileage, the show-and-stance crowd matching front and rear, and anyone tired of dragging, uneven back brakes. Choose your pad compound and caliper finish and you get a clean, serviceable setup that wakes the rear axle back up.

What this big brake kit does for your 2009-2015 Toyota Prius (XW30)

Fresh calipers and a larger rotor give the back of the car a firmer, more even bite than the worn factory hardware most XW30s are carrying by now. The two-piece floating disc sheds heat better under repeated stops and on long descents, so the rear pedal stays consistent instead of going soft and wooden. Three pad compounds, Street, Sport and Racing, let you match the rear bias to how you actually drive, from quiet commuting to harder road work. And because a regen-braked Prius asks so little of its rear brakes day to day, freeing up that axle also helps cure the uneven, lopsided pad wear these cars are notorious for.

About the Hollow rear brake kit

The kit pairs an oversized two-piece floating rotor with a bolt-on caliper and bracket designed around the XW30’s rear hub geometry. The hollow-body caliper is fitted as standard, cast with internal voids to cut weight at the corner while staying rigid, and the disc removes material where it does no braking work, keeping rotational and unsprung mass down while still gaining diameter over the standard rear disc. Painted calipers come in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a Custom Color in any Pantone and premium polished-forged and candy finishes, so the rear matches your wheels and any front upgrade. Discs come drilled or slotted at the same price, with two-tone anodized or titanium centre bells. The three friction-pad compounds cover quiet Street road use, a firmer Sport pad, and a Racing compound for harder duty, with a Hollow Racing caliper rated to 1000C available for the hardest use. The whole assembly is built to be serviced rather than binned, which matters on a Prius many owners keep running well past six figures.

Fitment for the Toyota Prius (XW30) (2009-2015)

Built for the third-generation XW30 Prius across the full 2009-2015 production run, this kit fits the rear axle only, as a left-and-right pair, and is designed around the standard XW30 hub and disc layout. Confirm your car is an XW30, not the earlier XW20 or later XW50, before ordering, as the rear brake hardware differs between generations.

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.
