2012-2018 Audi A7 / S7 / RS7 (C7) CCB Big Brake Kit — Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
C7 A7, S7, and RS7 owners usually shop carbon ceramic brakes because the car is heavy, fast, and hard on iron rotors during repeated highway-speed stops, mountain driving, or track sessions. This StopFlex kit uses 380 mm front and rear carbon-ceramic rotors with a Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper front setup and TTSPORT EP4 EPB rear calipers to add thermal capacity, reduce brake dust, and cut rotating unsprung mass. Each kit is built to the confirmed A7, S7, or RS7 trim so rotor-hat offset, brackets, and wheel clearance are matched to the exact car instead of treated as a generic C7 fit.
- 380 mm front and rear carbon-ceramic rotors require 19 inch or larger wheels; wheel spoke clearance must be checked against the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper.
- The front axle uses the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper, giving this C7 A7/S7/RS7 kit an OEM-derived six-piston front upgrade rather than an unbranded universal caliper.
- The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB so the C7 electronic parking brake function is retained while the rear rotor is upgraded to 380 mm carbon ceramic.

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 Akebono OEM Audi RS 6-Piston (8N) Caliper, a six-piston fixed caliper chosen for stable pad loading and consistent pedal response under repeated high-energy stops. Its OEM Audi RS provenance matters on the C7 A7/S7/RS7 because the caliper is based on a production performance application rather than a generic aftermarket casting. StopFlex pairs it with a 380 mm carbon-ceramic rotor, model-specific hats, brackets, lines, pads, and hardware for the buyer’s confirmed trim.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB, adding hydraulic rear service braking while preserving the factory electronic parking brake. On this 380 mm rear setup, the EP4 helps keep rear-axle heat capacity and brake balance in line with the upgraded six-piston front system.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so the 380 mm front Akebono package is not paired with an under-capacity rear brake. The TTSPORT EP4 uses four hydraulic service pistons plus one dedicated EPB actuator piston, so the C7 keeps OE parking-brake convenience while the rear axle gains carbon-ceramic thermal capacity.
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 every 2012-2018 Audi A7, S7, and RS7 the same way?
No. StopFlex confirms the exact A7, S7, or RS7 trim before engineering the kit because C7 models can differ in uprights, hubs, brake package, and wheel clearance. Brackets, rotor-hat offsets, and caliper mounting are matched to the confirmed car, not assumed from the shared C7 chassis.
What wheel size is required for the 380 mm setup?
The largest rotor in this kit is 380 mm, so wheels under 19 inches will not clear it. A 19 inch or larger wheel is still subject to spoke clearance because the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper has more outboard caliper volume than many factory iron-brake setups.
Will the electronic parking brake still work?
Yes. The rear kit uses the TTSPORT EP4 4-Piston Caliper with EPB, which uses four hydraulic service pistons for braking and a dedicated EPB actuator piston for parking-brake function. The goal is to retain the C7’s factory EPB behavior while upgrading rear braking hardware.
Why choose carbon ceramic on a C7 A7, S7, or RS7 instead of another iron big brake kit?
Carbon-ceramic rotors reduce brake dust, lower rotating unsprung mass, and tolerate repeated high-temperature stops better than conventional iron rotors. On a heavy C7 driven hard, the 380 mm StopFlex setup targets heat management, cleaner wheels, and more consistent pedal feel without relying on a front-only upgrade.
