Fits Citroen C4 PICASSO (2013-2022)

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 — Citroen C4 PICASSO (2013-2022) — 380 mm
380 mm

The C4 Picasso carries its mass high and well forward, a tall EMP2-platform MPV that asks a lot of its brakes the moment you add five occupants, a boot full of luggage and a motorway slip road. This XYZ Racing hollow rear brake kit upgrades the back axle of the 2013-2022 car, where the standard setup is sized for economy rather than repeated hard stops.

Rear braking on a nose-heavy front-driver like the Picasso is about stability as much as outright stopping power. The kit is a matched pair of rear calipers and discs for the back of the car: a larger, better-cooled rear disc keeps the back settled under heavy braking with a full load, and resists the fade that creeps in on a long descent or a fully laden run.

What this brake kit does for your 2013-2022 Citroen C4 Picasso

Fit this kit and the first thing you notice is a firmer, more reassuring pedal when the car is loaded. The hollow-vane disc design sheds weight from the rear corners, trimming rotating and unsprung mass so the rear suspension can follow the road more faithfully. Better cooling means the rear pads hold their bite through repeated stops rather than going soft halfway down a hill. With three pad compounds to choose from, you can match the rear axle to how the car is actually used, from school-run duty to a heavily loaded tow or trip: Street for quiet, low-dust daily driving, Sport for firmer fast-road bite, and Racing for the hardest work. Caliper finishes run from the no-cost painted colours through to premium polished and candy options if you want the rear hardware to match the rest of the car.

About the Hollow Rear Brake Kit

This is a rear-axle brake kit built around a hollow-body caliper and two-piece floating discs that improve airflow and reduce rotating mass compared with the factory rear setup. The hollow-vane construction helps the disc shed heat faster, which is what keeps braking consistent when the C4 Picasso is working hard, and the caliper is hollow-body as standard. The discs come drilled or slotted at the same price, with braided lines fitted to firm up the pedal, and serious users can specify the optional Hollow Racing upgrade rated to 1000C with no dust cover and a two-year warranty. Three pad compounds cover the range: Street for everyday road use, Sport for a firmer fast-road bite, and Racing for the most aggressive duty. Painted calipers come in Red, Yellow, Gold, Black and Anodized Black at no extra cost, with any Pantone shade available as a Custom Color for a small upcharge, plus premium polished-forged finishes (Titanium, Polished Gold, Polished Silver) and candy finishes (Candy Teal, Candy Blue, Candy Red, Candy Orange). Two-tone centre bells in five anodized colours or titanium round out the choices. It is a bolt-on upgrade for the rear of the car, sized specifically for the Picasso rather than adapted from another platform.

Fitment for the Citroen C4 Picasso (2013-2022)

This kit fits the second-generation Citroen C4 Picasso built from 2013 to 2022, covering both the five-seat Picasso and the longer Grand C4 Picasso of the same era. It is a rear-position kit, so it complements rather than replaces a front upgrade.

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.
