Fits Ford FOCUS ST MK4 WAGON (TYPE II) (2019-2026)

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 — Ford FOCUS ST MK4 WAGON (TYPE II) (2019-2026) — 356 mm
356 mm

The MK4 Focus ST carries its 2.3 EcoBoost mass over the front axle, so the rear brakes usually play a supporting role, right up until you trail-brake into a tightening corner or string together a long braking zone with a loaded boot. On the wagon that calculus shifts again: the estate body and whatever you have packed behind the rear seats sit aft of the rear axle, asking more of rear discs that were specified for a hatchback. This XYZ Racing rear big brake kit gives the back end of the 2019-2026 Focus ST MK4 Wagon (type II) the thermal headroom to keep pulling its weight when you brake hard and brake often.

Match the kit to how you drive. The two-piece floating disc design runs lighter than a solid rear rotor and sheds heat quickly, while three pad compounds let you set the rear bias for road use, fast-road work or circuit days. For an estate that moonlights as both a daily and a weekend track car, that range of choice is the point.

What this big brake kit does for your 2019-2026 Ford Focus ST MK4 Wagon (type II)

The first thing you notice is pedal consistency. Where a tired factory rear setup starts to go long after a few hard stops, the larger rear discs hold their bite and keep the pedal firm. On a front-driven car that pays off mid-corner: a rear axle that brakes cleanly helps the nose tuck on the way in rather than washing wide. The reduction in rotating and unsprung mass at the rear sharpens how the car settles over kerbs and broken surfaces, and the Racing compound gives you the rear stopping force a circuit session demands. Street keeps things quiet and low-dust for the commute, with Sport in between for fast-road duty. Pick a caliper finish and the hardware looks the part behind the spokes.

About the Rear Brake Kit

The rear brake kit is supplied as a matched pair of two-piece floating discs and calipers sized for the MK4 Focus ST’s rear axle. The rotors run internal hollow vanes to trim rotating and unsprung mass while still shifting heat away from the friction surface, and they come drilled or slotted at the same price. Three pad compounds cover the spread of how these cars get used: Street for quiet everyday driving, Sport for harder road and occasional track work, and Racing for sustained circuit heat. The hollow-body caliper is standard, with an optional Hollow Racing upgrade for serious track use that drops the dust cover, is rated to 1000C and carries a two-year warranty. Included painted finishes are Red, Yellow, Gold, Black and Anodized Black at no extra cost, with a custom Pantone colour at £150, plus premium polished-forged Titanium, Polished Gold and Polished Silver and candy Teal, Blue, Red and Orange. Centre bell upgrades run to a two-tone anodized finish in five colours, or titanium. Everything here is built around the rear position, complementing rather than replacing the heavier-duty front brakes a front-wheel-drive car leans on.

Fitment for the Ford Focus ST MK4 Wagon (type II) (2019-2026)

This kit is cut for the rear axle of the Ford Focus ST MK4 Wagon (type II) across the 2019 to 2026 model years, the type II estate, not the hatch. It is supplied as a pair for the back of the car. Confirm your car falls inside that range, then set your pad compound and caliper colour. Nothing about the front axle is included in this rear-only kit.

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.
