XYZ Racing Rear Brake Kit — Hyundai CUSTO/CUSTIN (KU) (2021-2026)

A fully loaded Custo/Custin (KU), seven aboard and the boot packed for a family trip, puts far more weight over the rear axle than the kerb figure suggests, and that extra mass is what cooks a marginal rear brake on a long descent or a string of motorway slowdowns. The XYZ Racing Hollow Rear Brake Kit for the Hyundai Custo/Custin (KU) tackles the heat problem at the back of this 2021-2026 MPV directly, with a hollow-vane rotor that sheds temperature faster than the cast unit it replaces.

This is a rear-axle kit, so it works alongside your front brakes to rebalance the van under heavy braking rather than simply adding clamp. You pick the pad compound to match how the vehicle gets used: Street for everyday family duty, Sport for harder fast-road work, Racing where sustained high temperatures are the norm.

What this brake kit does for your 2021-2026 Hyundai Custo/Custin (KU)

The headline gain is fade resistance. The hollow-vane rotor keeps rotating mass down while opening up internal heat paths, so the rear axle holds a consistent pedal when the Custo/Custin is heavy and the descent is long. You feel that as a firmer, more repeatable brake rather than the soft, lengthening pedal a tired standard disc gives once it heat-soaks. Matching stronger rear bite to the front setup also settles the back of the van on turn-in, which matters in a tall MPV that can feel vague when its rear brakes are working at their limit. With three pad compounds available, the same hardware suits a school-run van or a fully laden long-hauler without swapping the kit underneath.

About the Hollow rear brake kit

XYZ Racing builds this kit around a hollow-vane rotor, a disc whose internal construction removes material to cut rotating weight while widening the surfaces that carry heat away from the pad face. The two-piece floating rotor runs cooler still, and the caliper body is hollow as standard. Less rotating mass at the rear means the brake responds faster and recovers temperature between applications more readily than a solid casting. The kit is offered with three pad compounds: a Street compound for quiet, low-dust road use, a Sport compound for owners who drive harder or carry more, and a Racing compound for sustained high-temperature work. Discs come drilled or slotted at the same price. Calipers are finished in Red, Yellow, Gold, Black or 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 rear setup can be matched to the rest of the car. Every part here is specified for the rear axle of the Custo/Custin, so the geometry and clamping are sized to the load that platform puts through its back wheels.
