Caliper render for this kit:

The MK4 Octavia’s 4WD models split torque through a Haldex coupling and ride on a multilink rear axle, which means the back end does more braking work than the front-biased layout first suggests. This XYZ Racing rear brake kit for the Skoda Octavia MK4 (NX) 4WD (2019-2026) puts a matched pair of larger two-piece floating discs and fixed calipers where the standard sliding setup runs out of thermal headroom.
On a car this size, a long-wheelbase hatch or a Combi estate that loads up well past 1.5 tonnes, rear brake temperature is what decides whether your pedal stays consistent on a downhill B-road or a busy track session. The rear axle is the half of the braking system owners usually leave standard, and it is the half that goes soft first under repeated heavy stops.
What this brake kit does for your 2019-2026 Skoda Octavia MK4 (NX) 4WD
Fit the rear kit and the first thing you feel is a firmer, more linear pedal, because the larger rotor and fixed caliper resist the flex and fade that creep into the standard sliding-caliper arrangement. The two-piece floating discs shed rotating and unsprung mass at the rear axle, which sharpens turn-in and lets the multilink suspension settle faster over mid-corner bumps. With the Racing pad compound, bite arrives earlier and holds through a full track session; the Street compound trades a little outright bite for quieter, lower-dust daily manners, with Sport between the two for fast road. Crucially, brake balance shifts rearward in a controlled way, so the front axle is no longer doing nearly all the work and cooking itself on long descents.
About the rear big brake kit
XYZ Racing builds this as a bolt-on rear upgrade rather than a full custom job, pairing two-piece floating discs with fixed calipers sized for the Octavia’s rear hubs. The disc is the headline: its hollow-vane internal structure pulls heat out of the friction surface faster than a solid or basic vented rotor while removing mass that the wheel has to spin and the suspension has to control, and the floating mount lets the friction ring expand under heat without warping its alloy bell. Disc faces come drilled or slotted at the same price, chosen when you order. Three pad compounds cover the spread of use, Street for road drivers who want a straight upgrade, Sport for harder fast-road work, and Racing for track and time-attack duty. The caliper bodies are hollow-cast as standard, with an optional Hollow Racing upgrade for dedicated track cars that removes the dust cover, is rated to 1000C and carries a two-year warranty. Calipers are finished in Red, Yellow, Gold, Black or Anodized Black at no extra cost, with a custom Pantone match available, so the kit reads as deliberate behind an open wheel. It is specified to work with the car’s existing master cylinder rather than against it.
Fitment for the Skoda Octavia MK4 (NX) 4WD (2019-2026)
This kit is cut for the MK4 Octavia (NX-generation) in 4WD form, covering the 2019 to 2026 model years. It fits the rear axle of the Haldex all-wheel-drive cars specifically, the multilink-equipped chassis, rather than the front-drive variants. Confirm your car is the 4×4 version before ordering, since the rear hub and axle differ from the front-wheel-drive Octavia.

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.
