Caliper render for this kit:

The YF Sonata is a big, nose-heavy front-driver, and that weight bias leaves the rear axle doing comparatively little braking work from the factory. The XYZ Racing Hollow Rear Brake Kit for the Hyundai Sonata 8 YF rebalances that picture, giving the back of the car a properly specified pair of discs and calipers to lean on when you start using the brakes hard.
On a saloon this size, originally tuned for comfort, the standard rear brakes go vague quickly once the car is worked. A tuned 2.0T build, a fast-road set-up, or repeat downhill stops will all find their limit. This kit pairs a hollow-vane rotor with a dedicated caliper and a choice of pad compound, so the rear axle contributes consistent, fade-resistant bite instead of dropping out of the conversation.
What this rear big brake kit does for your 2010-2014 Hyundai Sonata 8 YF
After fitting, the first thing you feel on the 2010-2014 Hyundai Sonata 8 YF is a firmer, more predictable rear-end response under braking. With a properly specified disc and caliper at the back, the car stays more settled when you brake into a corner, and the nose dives less abruptly as the rears take a fair share of the load. The pad compound choice lets you match the kit to how you drive: the Racing compound holds its bite through repeated heavy stops where the factory rears would go soft, the Sport compound steps up heat range for fast road, and the Street option keeps things quiet and low-dust for daily use. The hollow rotor’s lower rotating mass also takes a small edge off the heavy YF’s stopping effort.
About the Hollow rear brake kit
The Hollow rear brake kit is a rear-axle pair of discs and calipers built around a hollow-vane rotor that trims rotating and unsprung mass over a comparable solid disc, which helps the rear wheels settle more quickly over bumps mid-corner. The two-piece floating rotors run cooler under load, and the caliper body is hollow as standard. It clamps with a dedicated caliper rather than the factory unit, and you choose from three pad compounds: Street for quiet, low-dust road use, Sport for fast-road duty with stronger bite once heat is in the system, and Racing for sustained high-temperature track work. Discs come drilled or slotted at the same price. Caliper finishes run to Red, Yellow, Gold, Black and Anodized Black at no extra cost, with premium polished-forged Titanium, Polished Gold and Polished Silver, candy Teal, Blue, Red and Orange, or any Pantone shade as a custom colour, so the hardware behind the wheels suits the look of the car. Everything is sized specifically for the rear of the Sonata 8 YF rather than adapted from another platform.
Fitment for the Hyundai Sonata 8 YF (2010-2014)
This kit fits the Hyundai Sonata 8 YF across the full 2010-2014 production run and mounts at the rear axle.

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.
