2026-2026+ Zeekr 9X CCB Big Brake Kit — Genuine AP Racing Mono E CP7411 10-Piston Caliper Front + Genuine AP Racing CP9582 4-Piston Caliper Rear Setup
The 2026+ Zeekr 9X is a 5.24-meter plug-in hybrid SUV with up to 1,030 kW in Hyper trims, so repeated high-speed stops ask far more of the brakes than normal luxury-SUV commuting. This StopFlex kit pairs 420mm front carbon-ceramic rotors with Genuine AP Racing Mono E CP7411 10-Piston Calipers and 380mm rear rotors with Genuine AP Racing CP9582 4-Piston Calipers to add heat capacity, reduce iron-rotor dust, and cut rotating mass at all four corners. Each kit is built around the confirmed 9X trim, wheel package, hub geometry, and caliper clearance, not assumed from the chassis name.
- 420mm front carbon-ceramic rotors require 21-inch or larger wheels on the Zeekr 9X; spoke clearance is checked separately from wheel diameter.
- The front axle uses the Genuine AP Racing Mono E CP7411 10-Piston Caliper, matched to the 420mm rotor for the braking load of a 2,840-3,150 kg 9X trim range.
- The rear axle uses a 380mm carbon-ceramic rotor with a Genuine AP Racing CP9582 4-Piston Caliper so rear torque, stability, and ABS behavior are engineered with the front upgrade.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 420 mm front rotor, so the minimum wheel size is 21". Wheels under 21" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front upgrade uses the exact Genuine AP Racing Mono E CP7411 10-Piston Caliper, giving the Zeekr 9X a large multi-piston pad load path for stable clamping force and consistent pedal response as rotor temperature rises. AP Racing is a proven performance-brake manufacturer, and this genuine caliper is selected for a high-output, heavy SUV rather than a cosmetic caliper swap. StopFlex matches the caliper position, bracket geometry, and rotor-hat offset to the buyer's confirmed 9X trim and wheel package.
Rear Caliper (Balance)
The rear upgrade uses the Genuine AP Racing CP9582 4-Piston Caliper with a 380mm carbon-ceramic rotor to keep the rear axle contributing controlled brake torque instead of leaving the car front-heavy under repeated stops. EPB integration is handled in the rear system specification so the factory electronic parking-brake function is retained where equipped.
Front & rear, engineered together: The Zeekr 9X kit is engineered as a front-and-rear system so piston area, rotor diameter, pad compound, and hydraulic balance work together with the vehicle's ABS and stability controls. A front-only mismatch can create excess front bias and leave the rear axle underused on a heavy 4WD plug-in hybrid SUV.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact Zeekr 9X trim?
Fitment is confirmed per vehicle before production. Max, Ultra, Hyper, and Radiant Black Edition trims can differ in weight, output, track, wheel package, and clearance, so StopFlex builds the brackets, rotor-hat offsets, and caliper mounting for your exact 9X rather than claiming one platform-wide bolt-on kit.
What wheels do I need for the 420mm front rotors?
The 420mm front rotor requires 21-inch or larger wheels. Wheel diameter alone is not enough; StopFlex also checks spoke shape, inner barrel profile, offset, and caliper envelope for the Genuine AP Racing Mono E CP7411 10-Piston Caliper.
Will the electronic parking brake still work?
Yes, the rear package is specified to retain the factory EPB function on equipped Zeekr 9X trims. EPB compatibility is verified during order confirmation because rear-caliper hardware and parking-brake integration must match the exact vehicle configuration.
Why choose carbon-ceramic rotors on a Zeekr 9X instead of iron rotors?
Carbon-ceramic rotors reduce brake dust, reduce rotating mass, and tolerate repeated high-temperature stops better than conventional iron rotors. On the Zeekr 9X, the benefit is most noticeable during mountain driving, repeated highway deceleration, and use with open 21-inch or larger wheels where dust and brake appearance are visible.
