2019-2026+ Porsche Cayenne (9Y0) / S / E-Hybrid CCB Big Brake Kit — Genuine Akebono OEM Porsche 10-Piston (10N) Caliper Front + Genuine Brembo OEM Porsche 19Z 4-Piston Caliper Rear Setup
The 2019-2026+ Porsche Cayenne 9Y0 / S / E-Hybrid is heavy enough to overwork factory iron brakes during repeated high-speed stops, mountain driving, towing, or track-day use, and open Porsche wheels make iron dust easy to see. This StopFlex kit pairs a Genuine Akebono OEM Porsche 10-Piston (10N) Caliper with 420/440 mm front carbon-ceramic rotors and a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper with 410/380 mm rear rotors for higher heat capacity, lower rotating mass, reduced dust, and a factory-caliber appearance. Every kit is engineered to the confirmed Cayenne trim, brake package, wheel clearance, and hub geometry so bracket position and rotor-hat offset are not guessed from the 9Y0 chassis name.
- 420 mm is the largest front rotor in this Cayenne 9Y0 kit, so 21-inch wheels are the minimum; spoke clearance and wheel offset still need confirmation before production.
- The front axle uses the exact Genuine Akebono OEM Porsche 10-Piston (10N) Caliper with 420/440 mm carbon-ceramic rotors for repeated-stop heat capacity on a high-mass SUV.
- The kit keeps the Porsche pad-wear warning system functional with compatible wear sensors, so the factory pad-wear alerts remain active without dashboard errors.

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 built around the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper, a ten-piston OEM Porsche-derived fixed caliper that spreads clamping load across the pad for consistent pedal response under repeated heavy braking. Its credibility comes from being a genuine OEM-derived Porsche caliper, not a generic aftermarket casting, and it is paired here with 420/440 mm StopFlex carbon-ceramic rotors, hats, pads, lines, and hardware matched to the confirmed Cayenne configuration.
Rear Caliper (Balance)
The rear axle uses a Genuine Brembo OEM Porsche 19Z 4-Piston Caliper with 410/380 mm carbon-ceramic rotors to keep rear brake contribution proportional to the larger front system. The rear package is engineered to retain the Cayenne’s factory electronic parking brake function and Porsche pad-wear monitoring compatibility.
Front & rear, engineered together: The front and rear systems are specified together so hydraulic balance, rotor thermal capacity, pad behavior, and rear stability are matched instead of adding a large front kit to an unchanged rear brake package. For a Cayenne 9Y0 / S / E-Hybrid, that matters because vehicle mass and rear axle load can make a front-only mismatch feel unstable during repeated high-speed braking.
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 2019-2026+ Cayenne 9Y0, S, or E-Hybrid?
Fitment is confirmed per vehicle before production. StopFlex matches the brackets, rotor-hat offsets, caliper mounting, brake lines, and hardware to your exact Cayenne 9Y0 trim and factory brake configuration rather than treating every 9Y0 chassis as mechanically identical.
What wheel size do I need for the 420 mm front rotor setup?
Plan on 21-inch wheels minimum because the largest front rotor in this kit is 420 mm. Wheel diameter alone is not enough; StopFlex also checks wheel offset, barrel shape, and spoke clearance around the Genuine Akebono OEM Porsche 10-Piston (10N) Caliper.
Will the electronic parking brake and pad-wear warning still work?
Yes. The rear package is engineered around the Cayenne 9Y0 factory electronic parking brake system, and the kit uses wear-sensor compatibility so the Porsche pad-wear warning continues to function without dashboard errors.
Why switch this Cayenne from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, cut rotating and unsprung mass, and tolerate repeated high-temperature stops better than conventional iron rotors. On a Cayenne 9Y0 used for fast road driving, towing, mountain descents, or track sessions, the payoff is cleaner wheels, more stable pedal behavior, and less heat stress in repeated braking.
