What Does a Brake Wheel Cylinder Do?
Inside every rear drum brake assembly, the wheel cylinder is what actually makes the brakes work. Hydraulic pressure from the master cylinder travels down the brake line and into this cylinder. Two pistons inside push outward in opposite directions, pressing the brake shoes against the drum and slowing the vehicle down.
On light commercial vehicles like the Kangoo and Kubistar — vans that spend most of their working life in urban delivery routes — the rear brakes handle a predictable share of stopping force on every run. A leaking or seized wheel cylinder shows up as uneven braking, fluid on the backing plate, or a soft pedal that gradually gets worse. It's a straightforward repair, but the cylinder has to be the right bore size. XUI2818A is built to 22.22mm — the OE specification for these applications.

Mexico Market and European Coverage — Two Separate Demand Streams
This is one of the few wheel cylinder SKUs that serves both a Latin American market fitment and a European one within the same part number. That's worth understanding for catalog planning.
The Renault Kangoo sold in Mexico ran on the same basic platform as the European version but with a longer production lifecycle. Kangoo models sold in Mexico between 2004 and 2015 are still actively serviced — Mexico's vehicle fleet skews older than North American averages, and parts availability for these vans is a known gap in the local aftermarket. Distributors with access to this SKU have an advantage in a market where Dorman W619011 is the most recognizable reference point for buyers.
On the European side, the Nissan Kubistar (X76) was sold across Western Europe from 2003 to 2009 as a light delivery van. It shared the Kangoo's rear drum brake setup entirely. Workshop demand for Kubistar parts in France, Spain, and Eastern Europe continues from the remaining vehicle population still in service.
Fleet maintenance buyers know that on a van doing 30 to 40 stops a day, rear brake components don't last forever. A shop servicing a small delivery fleet of Kangoos or Kubistar vans will go through these cylinders regularly — not once. That's the reorder pattern that makes this a worthwhile stocking SKU rather than a one-off purchase.

Q: What is the bore diameter of XUI2818A?
22.22mm — this is the OE specification for rear drum brake cylinders on the Kangoo and Kubistar platform. Using the wrong bore size affects braking pressure and is a safety issue. Always confirm before substituting.

Q: Is the Nissan Kubistar fitment the same as the Renault Kangoo?
Yes. The Kubistar X76 was built on the Kangoo platform under the Renault-Nissan Alliance. The rear brake assembly is identical, and both OE numbers cross to the same cylinder.

Q: Does XUI2818A fit the European Kangoo or only the Mexico market version?
The application list covers Mexico-market Kangoo variants (2004–2015) and the Nissan Kubistar sold in Europe (2003–2009). If you are sourcing for European Kangoo models outside of Mexico, verify the OE number against your specific vehicle before ordering.

Q: Is this supplied as a single cylinder or as an axle set?
Single cylinder per unit. Rear drum brake service typically requires replacement in pairs — order two units per axle.

Q: Does Dorman W619011 cross directly to XUI2818A?
Yes — same bore diameter, same mounting dimensions, direct replacement.
