2015-2020 Mercedes-Maybach S500 / S550 / S560 / S600 / S650 (X222) CCB Big Brake Kit — Genuine Alcon RC6 6-Piston Caliper Front + Genuine Alcon RC4 4-Piston Caliper Rear Setup
The X222 Mercedes-Maybach is a long-wheelbase, high-mass S-Class, so brake heat, rotor wear, and wheel dust become the real reasons to move beyond the factory iron setup. This StopFlex kit uses 380mm carbon-ceramic rotors with a Genuine Alcon RC6 6-Piston Caliper front upgrade and Genuine Alcon RC4 4-Piston rear calipers to add heat capacity, reduce unsprung rotating mass, and keep the visual scale correct behind 19-inch-or-larger wheels. Each kit is built against the buyer’s confirmed S500, S550, S560, S600, or S650 configuration, not a generic X222 assumption.
- 380mm front and rear carbon-ceramic rotors are the largest rotors in this package and require 19-inch or larger wheels; spoke clearance must still be checked before build approval.
- The front axle uses the exact Genuine Alcon RC6 6-Piston Caliper specified for this Maybach X222 kit, paired with carbon-ceramic rotors, pads, hats, hardware, and lines.
- The X222 Maybach’s long wheelbase and high curb weight make repeated highway braking, mountain descents, and chauffeured stop-start use harder on iron rotors and pad-dust control than on a shorter, lighter sedan.

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 upgrade uses the Genuine Alcon RC6 6-Piston Caliper, giving the 380mm carbon-ceramic rotor a larger, more controlled clamping interface than the factory-style luxury-sedan brake package. Alcon is a known performance brake manufacturer, and this genuine caliper choice gives the kit credible motorsport-derived hardware rather than an unbranded casting. The caliper is matched to StopFlex brackets, rotor-hat offset, brake lines, and pad specification for the buyer’s confirmed X222 trim.
Rear Caliper (Balance)
The rear axle uses the Genuine Alcon RC4 4-Piston Caliper with a 380mm carbon-ceramic rotor so rear torque contribution is engineered with the front RC6 upgrade instead of being left as a factory mismatch. Because X222 Maybach models use an electronic parking brake system, rear fitment must be configured to retain factory parking-brake function where applicable.
Front & rear, engineered together: A 6-piston front and 4-piston rear package lets StopFlex manage brake torque, pedal response, and thermal capacity across both axles. Engineering the front and rear together is especially important on a heavy X222 Maybach because rear stability and ABS behavior depend on more than front rotor diameter alone.
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 Maybach S500, S550, S560, S600, or S650?
Fitment is confirmed per exact X222 trim before production. StopFlex does not treat every X222 as the same car; brackets, rotor-hat offsets, caliper mounting, brake lines, and clearance checks are matched to the confirmed model, driveline, and wheel package.
What wheel size do I need for the 380mm StopFlex carbon-ceramic kit?
The 380mm rotors require 19-inch or larger wheels. Barrel diameter is only the first check; spoke clearance for the Genuine Alcon RC6 front caliper and Genuine Alcon RC4 rear caliper must also be verified before the kit is built.
Will the electronic parking brake still work?
The X222 Maybach uses an electronic parking brake, so the rear package is engineered around EPB retention where applicable. StopFlex confirms the vehicle’s rear brake and EPB configuration before finalizing the rear caliper, hat, and hardware package.
Why switch this Maybach from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, cut rotating unsprung weight, and handle repeated heat cycles better than conventional iron rotors in demanding use. On a heavy long-wheelbase Maybach, those gains matter most during repeated high-speed stops, downhill driving, and owners who want cleaner open wheels.
