2024-2026+ Zeekr X CCB Big Brake Kit | Brembo FA042 6-Piston

2024-2026+ Zeekr X CCB Big Brake Kit — Genuine Brembo FA042 Forged 6-Piston Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup The 2024-2026+ Zeekr X is a quick, heavy EV crossover, so repeated high-speed stops put more heat into the brake system than a short urban test drive shows. This StopFlex kit uses 380 mm carbon-ceramic rotors with a Genuine Brembo FA042 Forged 6-Piston Caliper front setup and TTSPORT EP4 4-Piston Caliper with EPB rear setup to increase thermal capacity, reduce iron-rotor dust, and cut rotating unsprung mass. Each kit is built around the customer's confirmed Zeekr X trim and wheel package, including rotor-hat offset, brackets, and caliper position. 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels on the Zeekr X; spoke clearance is checked separately from wheel diameter. Front braking is handled by the exact Genuine Brembo FA042 Forged 6-Piston Caliper specified for this Zeekr X kit, not a generic 6-piston casting. Rear braking uses a TTSPORT EP4 4-Piston Caliper with EPB so the Zeekr X keeps electronic parking brake and Auto Hold functionality while adding rear-axle heat capacity. Fitment Hard Lines Field Specification Vehicle Zeekr X Model years 2024-2026+ Front setup Genuine Brembo FA042 Forged 6-Piston Caliper / 380mm Rear setup TTSPORT EP4 4-Piston Caliper with EPB / 380mm Page type Complete CCB kit upgrade Minimum wheel size 19" (for the 380 mm front rotor) 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. Wheel Size (Standard) Disc Range 15" 260 mm – 285 mm 16" 285 mm – 300 mm 17" 300 mm – 330 mm 18" 330 mm – 355 mm 19" 355 mm – 380 mm 20" 380 mm – 400 mm 21" 400 mm – 420 mm 22" 420 mm – 440 mm Caliper Overview — Front & Rear Balance Front Caliper (Primary Upgrade) The front axle uses the Genuine Brembo FA042 Forged 6-Piston Caliper, giving the Zeekr X six service pistons to distribute clamping force across the pad and keep pedal response more consistent under repeated stops. Its Brembo provenance matters because this is a genuine performance/OEM-derived caliper architecture, not an unbranded decorative caliper. The forged body construction is appropriate for a 380 mm carbon-ceramic front rotor where stiffness, heat control, and repeatable pad contact are the priority. Rear Caliper (Balance) The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB to add real rear service braking capacity without deleting the Zeekr X electronic parking brake. Its 4 hydraulic service pistons support rear brake stability, while the dedicated EPB actuator piston preserves factory parking-brake operation. Front & rear, engineered together: This kit is engineered as a front-and-rear system so the 380 mm front Brembo FA042 package and 380 mm rear EP4 package work together instead of overloading the front axle with a front-only mismatch. Matching brackets, rotor-hat offsets, pad compounds, and rear EPB hardware to the confirmed Zeekr X trim helps maintain brake bias, stability, and parking-brake function.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. Custom caliper color Custom caliper logo Custom rotor hat color 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.

Order scope Default listing is full-car set when front and rear are specified. Front-only or rear-only orders can be arranged after confirmation. 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. TTSPORT EP4S rear caliper specification (the EP4 shares the same engineering, slightly more compact): Specification EP4S Axle position Rear Piston count 4 hydraulic + 1 EPB actuator Piston type Two-piece heat-insulated, dust boots + EPB actuator Piston diameter 28 mm × 4 / 27 mm × 1 Total piston area 30.4 cm² per caliper Manufacturing process Two-piece forged aluminum body Net weight 4.50 kg per caliper (no pads) Surface finish High-temperature gloss coating Recommended wheel size 18 in or larger FAQ Will this StopFlex kit fit my exact 2024-2026+ Zeekr X trim?Fitment is confirmed per vehicle before production. StopFlex matches the brackets, rotor-hat offsets, and caliper mounting to your exact Zeekr X model year, market, trim, hub geometry, and wheel package rather than assuming every SEA-platform vehicle shares the same brake fitment.What wheel size is required for the 380 mm Zeekr X kit?The 380 mm front and rear rotors require 19 inch or larger wheels. Wheel diameter alone is not enough; StopFlex also checks spoke clearance, wheel offset, and caliper envelope against the Genuine Brembo FA042 front caliper and TTSPORT EP4 rear caliper.Will the electronic parking brake and Auto Hold still work?Yes, this rear package uses the TTSPORT EP4 4-Piston Caliper with EPB. The caliper has 4 hydraulic service pistons for braking plus a dedicated EPB actuator piston, so the Zeekr X keeps factory electronic parking brake convenience.Why choose carbon-ceramic rotors on a Zeekr X instead of iron rotors?Carbon-ceramic rotors reduce brake dust, reduce rotating unsprung mass, and tolerate repeated heat cycles better than conventional iron rotors. On the Zeekr X, the 380 mm CCB package is aimed at owners who want cleaner open wheels, stronger heat control, and consistent braking during fast road or repeated high-speed use.
