XYZ Racing Hollow Rear Brake Kit — Mazda CX-5 4WD (KF) (2017-2026)

The KF-generation CX-5 carries its all-wheel-drive hardware high and toward the rear, and on a crossover the size and weight of this one the factory rear discs are sized for commuting rather than for the heat a loaded car generates down a long descent or under repeated heavy stops. This XYZ Racing rear big brake kit replaces that setup on the 2017-2026 Mazda CX-5 4WD (KF) with larger, more thermally capable components and a choice of pad compound to suit how the car is actually driven.

Front brakes do most of the work on a nose-heavy crossover, but the rear axle is what sets brake balance and keeps the body settled. It is also the end that tends to fade first when you are towing, fully loaded with the family, or working the car on a twisting road. Bringing the rear’s capacity closer to the front is what this kit is for, and it ships as a pair of left and right rear calipers with matched discs.

What this brake kit does for your 2017-2026 Mazda CX-5 4WD (KF)

After fitting, the most obvious change is a firmer, more progressive pedal, with the larger swept area soaking up heat that would have the standard rear discs feeling wooden by the bottom of a hill. The three pad compounds let you match the kit to the job: the Street compound stays quiet and low-dust for daily duty, the Sport compound adds bite and a wider heat range for spirited B-road and towing use, and the Racing compound holds its friction when the discs are genuinely hot. Painted caliper finishes included at no extra cost (Red, Yellow, Gold, Black and Anodized Black), plus a Custom Color and the premium polished and candy ranges, mean the rear of the CX-5 4WD (KF) can either sit discreetly behind the wheels or read as a deliberate upgrade.

About the Hollow rear brake kit

The Hollow rear big brake kit is a bolt-on upgrade for the rear axle, pairing an uprated hollow-body caliper with a larger two-piece floating disc to increase both clamping force and thermal headroom over the standard Mazda parts. The extra disc mass and surface area give the kit more capacity to absorb and shed heat, which is where the standard rear brakes on a heavier 4WD crossover run short under sustained or repeated loads. 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 material is selected when you order from Street, Sport or Racing compounds, so the same hardware can be set up for refined road manners or for harder, hotter 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 track use. The caliper is offered in the included painted finishes through to a custom Pantone, so the look can be specified alongside the performance. It is engineered as a direct rear-axle fit, keeping installation straightforward while lifting the back end’s braking performance.
