2022-2026+ Mercedes-Maybach S580 / S680 (Z223) CCB Big Brake Kit — Genuine Brembo GT BM8 8-Piston Caliper Front + Genuine Brembo GT BM4 4-Piston Caliper Rear Setup
The Z223 Mercedes-Maybach S580 and S680 are heavy, high-output luxury sedans, so repeated high-speed braking, mountain driving, and stop-and-go heat can expose the limits of an iron rotor package through heat load, dust, and rotating mass. This StopFlex kit uses 410mm front carbon-ceramic rotors with Genuine Brembo GT BM8 8-Piston Calipers and 380mm rear carbon-ceramic rotors with Genuine Brembo GT BM4 4-Piston Calipers to add thermal capacity, reduce brake dust, and cut unsprung rotating weight. Each kit is built around the confirmed S580 or S680 Z223 configuration, including bracket geometry, rotor-hat offset, and wheel-clearance requirements.
- 410mm is the largest rotor in this StopFlex Z223 package, so 21-inch wheels are the minimum; wheels under 21 inches will not clear the front brake package.
- The front axle uses the exact Genuine Brembo GT BM8 8-Piston Caliper with a 410mm carbon-ceramic rotor for the primary heat and clamp-load demand of the Maybach S-Class chassis.
- The rear axle is upgraded with a Genuine Brembo GT BM4 4-Piston Caliper and 380mm carbon-ceramic rotor so rear contribution, stability, and visual balance match the front conversion.

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 410 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 axle uses the Genuine Brembo GT BM8 8-Piston Caliper, giving the Z223 Maybach a large multi-piston clamp package for controlled pad pressure across the 410mm carbon-ceramic rotor. Brembo GT hardware is a credible motorsport-derived performance-brake architecture, and the BM8 caliper gives this kit the stiffness and pad support expected in a high-mass S580 or S680 application. StopFlex matches the caliper mounting, bracket position, and rotor-hat offset to the confirmed vehicle rather than assuming all Z223 trims share identical brake geometry.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo GT BM4 4-Piston Caliper with a 380mm carbon-ceramic rotor to keep rear brake torque and thermal capacity in proportion with the BM8 front upgrade. The rear package is engineered around the Z223 factory electronic parking brake requirements so parking-brake and Auto Hold behavior can be retained when the confirmed trim configuration is supplied.
Front & rear, engineered together: A front-only big brake conversion can move too much work to the front axle and leave the rear axle thermally and visually mismatched. This StopFlex front-and-rear kit is specified as one system so piston area, rotor diameter, pad selection, hat offset, and bracket geometry are matched for the exact S580 or S680 build.
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 StopFlex kit fit my exact 2022-2026+ Maybach S580 or S680 Z223?
Fitment is built after the exact trim and vehicle configuration are confirmed. StopFlex specifies the brackets, rotor-hat offsets, and caliper mounting for the specific S580 or S680, not from a generic W223/Z223 assumption.
What wheel size is required for the 410mm front rotor?
The 410mm front rotor requires at least a 21-inch wheel. Diameter alone is not enough; spoke shape, barrel profile, and offset must also clear the Genuine Brembo GT BM8 8-Piston Caliper.
Will the electronic parking brake still work?
Yes, the Z223 Maybach S-Class uses a factory electronic parking brake, and the rear portion of this kit is engineered around EPB retention for the confirmed vehicle configuration.
Why choose carbon-ceramic over the factory iron brakes on a Maybach S580 or S680?
Carbon-ceramic rotors reduce brake dust, reduce rotating unsprung mass, and tolerate repeated heat cycles better than iron rotors in demanding high-speed use. On a heavy S-Class Maybach, those gains matter for brake consistency, wheel cleanliness, and steering response.
