Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2016-2026+ Audi Q7 / SQ7 (4M) CCB Big Brake Kit — Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The 4M Audi Q7 and SQ7 put SUV mass, quattro traction, and high-speed highway use into a brake package that many owners upgrade for heat capacity, brake dust reduction, and lower rotating weight. This StopFlex kit pairs a 420mm front carbon-ceramic rotor with the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper, then matches the rear with a TTSPORT EP4 4-Piston Caliper with EPB on a 380mm carbon-ceramic rotor. Each kit is built to the customer’s exact Q7 or SQ7 trim so the bracket geometry, rotor-hat offset, line routing, and caliper position are specified for that car, not guessed from the 4M chassis name.
- 420mm is the largest rotor in this Q7 / SQ7 package, so wheels under 21 inches will not clear the front brake; spoke clearance is checked separately before production.
- The front axle uses the exact Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper with a 420mm StopFlex carbon-ceramic rotor for heat capacity and firm pressure distribution on a heavy 4M SUV.
- The rear axle uses a TTSPORT EP4 4-Piston Caliper with EPB and a 380mm carbon-ceramic rotor, so the upgrade keeps electronic parking-brake function instead of deleting factory convenience features.

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 420 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 upgrade is the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper, a 10-piston OEM-derived Audi RS unit selected for broad pad loading, high clamp stability, and consistent pedal response on the 420mm rotor. Its credibility comes from genuine Akebono OEM Audi RS provenance rather than an anonymous aftermarket casting, which matters on a heavy Q7 / SQ7 where caliper stiffness and piston distribution affect confidence under repeated braking.
Rear Caliper (Balance)
The rear upgrade is the TTSPORT EP4 4-Piston Caliper with EPB, matched to a 380mm rear carbon-ceramic rotor to add rear thermal capacity without upsetting brake balance. The EP4 uses 4 hydraulic service pistons plus a dedicated EPB actuator piston, so the Q7 / SQ7 keeps electronic parking-brake operation.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so the 420mm Akebono 10-piston front package and 380mm EP4 rear package work together instead of leaving the rear axle thermally and hydraulically behind. StopFlex specifies the brackets, hats, and caliper positions for the confirmed Q7 or SQ7 trim so front bias, rear stability, and EPB compatibility are handled in one 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 420mm kit fit my exact Q7 or SQ7 trim?
StopFlex does not treat every 4M chassis as the same car. Before production, we confirm your model year, Q7 or SQ7 trim, factory brake package, hub and knuckle configuration, wheel size, and spoke profile, then build the brackets, rotor hats, lines, and caliper mounts for that exact vehicle.
What wheel size is required for the 420mm front rotor?
The 420mm front rotor requires 21 inch or larger wheels. Diameter alone is not enough; the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper also needs spoke clearance, so StopFlex verifies the wheel design before finalizing the kit.
Will the electronic parking brake still work?
Yes. This Q7 / SQ7 kit uses the TTSPORT EP4 4-Piston Caliper with EPB at the rear, which combines 4 hydraulic service pistons with a dedicated EPB actuator piston so factory parking-brake function is retained.
Why switch this Q7 / SQ7 from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, lower rotating and unsprung weight, and tolerate repeated high-energy stops better than typical iron street rotors. On the 4M Q7 / SQ7, that matters because the vehicle’s mass, tire grip, and highway-speed use put sustained heat into the brakes.
