2015-2020 Mercedes-Maybach S500 / S550 / S560 / S600 / S650 (X222) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
The X222 Mercedes-Maybach is a heavy long-wheelbase S-Class variant, so brake upgrades are usually about controlling repeated heat, reducing iron-rotor dust on large wheels, and cutting rotating mass without giving up street manners. This StopFlex kit pairs 380 mm carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-Piston Caliper Options up front and Brembo V4 / GT4 / GTS4 4-Piston Caliper Options at the rear. Brackets, rotor-hat offsets, brake lines, and caliper mounting are built around the buyer’s exact S500, S550, S560, S600, or S650 configuration instead of assuming every X222 shares the same clearance and hub geometry.
- 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels; spoke clearance must still be checked against the selected Brembo caliper profile.
- Front choices are V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, GT6 = Genuine Brembo GT | M6 6-Piston Caliper, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper, each paired with a 380 mm rotor.
- The X222 Maybach’s long-wheelbase mass makes repeated high-speed braking and brake dust control more relevant than a cosmetic caliper swap.

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 Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, giving the Maybach a rigid six-piston front clamp package sized around the 380 mm carbon-ceramic rotor. The buyer chooses V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, GT6 = Genuine Brembo GT | M6 6-Piston Caliper, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper; all are genuine Brembo-based options rather than unbranded castings. The six-piston layout helps distribute pad pressure across the rotor face for stable pedal response and controlled front-axle heat load.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options with 380 mm carbon-ceramic rotors to support rear brake torque without overloading the front axle. Rear hardware is engineered around the X222’s factory electronic parking brake requirements so parking-brake and hold-function compatibility can be addressed during fitment confirmation.
Front & rear, engineered together: The front and rear packages are specified together so piston area, rotor diameter, pad choice, and hydraulic behavior stay within a usable brake-bias window for the Maybach chassis. This avoids the common front-only problem where a larger front setup increases thermal capacity but leaves the rear axle, pedal balance, and stability calibration mismatched.
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 Mercedes-Maybach S500, S550, S560, S600, or S650?
Fitment is confirmed by exact X222 model, year, drivetrain, wheel package, and factory brake configuration before production. StopFlex does not treat every X222 or W222 variant as the same car; brackets, rotor-hat offsets, and caliper mounting are matched to your confirmed trim.
What wheel size is required for the 380 mm carbon-ceramic setup?
The 380 mm rotors require 19 inch or larger wheels. Wheel diameter alone is not enough; spoke shape, inner barrel clearance, offset, and the selected Brembo V6, GT6, or GTS6 caliper profile must be checked before the kit is built.
Will the electronic parking brake still work?
Yes, the X222 Maybach uses an electronic parking brake, and the rear package is engineered around that requirement during order confirmation. StopFlex verifies the rear configuration before finalizing the rear Brembo V4, GT4, or GTS4 caliper solution.
Why switch a Maybach X222 from factory brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, resist heat saturation better under repeated high-speed stops, and reduce rotating mass compared with typical iron rotors. On a heavy long-wheelbase Maybach, those benefits matter most for cleaner wheels, more consistent pedal behavior, and lower unsprung weight.
