XYZ Racing Hollow Rear Brake Kit — Mazda CX-5 2WD (KF) (2017-2026)

The KF-generation CX-5’s height and forward weight bias mean its rear brakes spend most of their life as the supporting cast, right up until you load four adults and a full boot, hook a trailer to the back, or string together a run of downhill stops on a Welsh A-road. That is when the rear axle of a front-driven crossover finally has to work, and where the standard discs begin to heat-soak and go long underfoot.

The XYZ Racing Hollow Rear Brake Kit for the Mazda CX-5 2WD (KF) targets exactly that weakness. It is a rear big brake kit, a pair of left and right rear calipers with matched discs, built to add thermal headroom and a firmer, more repeatable pedal to a tall, comfort-tuned SUV that was never set up for sustained heavy braking.

What this big brake kit does for your 2017-2026 Mazda CX-5 2WD (KF)

The first thing you feel on a 2017-2026 Mazda CX-5 2WD (KF) is a rear axle that bites cleanly instead of trailing the fronts, which sharpens brake balance when the car is laden or towing. The hollow rotor design trims rotating mass at each rear hub, so the brakes shed heat faster and stay consistent through repeated stops rather than fading after a long descent. Three pad compounds, Street, Sport and Racing, let you match the rear bite to how the car is actually used, from quiet school-run duty through spirited B-road work to track days. The result is a longer, more confident pedal under load and less of the soft, distant feel the factory rears develop when hot.

About the Hollow Rear Brake Kit

The Hollow Rear Brake Kit takes its name from its lightweight hollow-body caliper and disc construction, which cuts unsprung and rotational mass over a solid rotor of the same size while keeping the larger swept area a big brake kit needs. The multi-piston caliper clamps a bigger two-piece floating disc than standard, increasing torque at the rear axle and giving the system more thermal mass to absorb heat before fade sets in. Discs are offered drilled or slotted at the same price, with two-tone anodized centre bells in five colours or titanium selectable at checkout. Pad choice spans Street for everyday road use, Sport for harder fast-road driving with a wider heat range, and Racing for track and high-load work. The hollow-body caliper is standard, with an optional Hollow Racing upgrade rated to 1000C, no dust cover and a two-year warranty for serious circuit use. Calipers are finished in your choice of the included painted colours, Red, Yellow, Gold, Black and Anodized Black, or a custom Pantone, plus premium polished-forged and candy ranges, so the look behind the wheels matches the rest of the build.
