2025-2026+ Zeekr 007 GT CCB Big Brake Kit — Genuine Alcon RC6 6-Piston Caliper Front + Genuine Alcon RC4 4-Piston Caliper Rear Setup
The 2025-2026+ Zeekr 007 GT is a heavy, high-torque electric shooting brake, with AWD versions reaching 475 kW and curb weights above 2,300 kg, so repeated high-speed stops can put more heat into the factory iron brakes than casual street driving ever shows. This StopFlex kit replaces both axles with 380 mm carbon-ceramic rotors, a Genuine Alcon RC6 6-Piston Caliper in front, and a Genuine Alcon RC4 4-Piston Caliper in the rear to increase thermal capacity, reduce brake dust, and cut rotating mass at the wheel. Every bracket, rotor hat, line, and caliper position is built around the customer’s confirmed 007 GT trim and wheel package, not a generic Zeekr platform assumption.
- 380 mm front and rear carbon-ceramic rotors are sized for the 007 GT’s EV mass and torque; wheels under 19 inches will not clear, and spoke clearance must be checked before ordering.
- The front axle uses the exact Genuine Alcon RC6 6-Piston Caliper paired with a 380 mm StopFlex CCB rotor, pads, hats, hardware, and stainless lines.
- RWD and AWD 007 GT trims differ in curb weight, motor layout, ride height, and wheel package, so StopFlex confirms the exact trim before machining brackets and rotor-hat offsets.

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 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" 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 axle uses the Genuine Alcon RC6 6-Piston Caliper, giving the 007 GT a six-piston clamping layout for more even pad loading and firmer pedal response under repeated deceleration. Alcon is a known motorsport and performance-brake manufacturer, and this genuine caliper is specified here as the primary upgrade rather than a cosmetic multi-piston casting. Its rigid performance-caliper construction works with the 380 mm carbon-ceramic rotor to manage heat and maintain pad contact across the swept area.
Rear Caliper (Balance)
The rear axle uses the Genuine Alcon RC4 4-Piston Caliper with a matching 380 mm carbon-ceramic rotor so rear torque contribution is engineered with the front system instead of left as a factory mismatch. EPB function is retained through the kit’s rear configuration for 007 GT trims equipped with factory electronic parking brake hardware.
Front & rear, engineered together: The RC6 front and RC4 rear package is engineered as a complete brake system so piston area, rotor diameter, pad compound, and rear parking-brake requirements are matched before production. That matters on the Zeekr 007 GT because regen blending, vehicle mass, and AWD/RWD weight distribution can make a front-only oversized kit feel inconsistent under hard braking.
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 2025-2026+ Zeekr 007 GT trim?
Fitment is bespoke per confirmed trim. StopFlex verifies whether your 007 GT is RWD or AWD, 75 kWh or long-range battery, model year, hub/knuckle details, factory brake package, and wheel dimensions before machining brackets and rotor hats.
What wheel size is required for the 380 mm carbon-ceramic rotors?
The 380 mm rotor is the largest rotor in this kit, so the minimum wheel diameter is 19 inches. Barrel clearance and spoke clearance still have to be checked because wheel ET, spoke shape, and inner barrel profile can vary even on the same Zeekr 007 GT trim.
Will the electronic parking brake still work?
Yes, the rear package is specified around the Zeekr 007 GT’s factory EPB requirement. StopFlex confirms the rear-caliper and parking-brake interface during order validation so parking, auto-hold related functions, and rear brake packaging are handled correctly.
Why choose carbon-ceramic instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust and rotating mass while giving the 007 GT more thermal headroom for repeated high-speed stops. For a heavy EV with strong regen and high torque, the payoff is cleaner wheels, lower heat sensitivity, and more consistent friction when mechanical braking is used hard.
