2009-2017 Audi Q5 / SQ5 (8R) CCB Big Brake Kit — Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The 2009-2017 Audi Q5 / SQ5 8R is heavy enough to overwork factory iron brakes during mountain driving, repeated highway stops, or track use, and the open-wheel look makes brake dust hard to ignore. This StopFlex kit uses a 420mm front carbon-ceramic rotor with the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper and a 380mm rear carbon-ceramic rotor with TTSPORT EP4 EPB calipers for higher thermal capacity, lower rotor mass, cleaner wheels, and retained parking-brake function. Every kit is built against the buyer’s exact Q5 or SQ5 trim so the bracket geometry, hat offset, and caliper position match the car being converted, not just the 8R chassis code.
- 420mm front carbon-ceramic rotors require 21-inch or larger wheels on the Audi Q5 / SQ5 8R; spoke clearance must also be checked before production.
- Front braking is handled by the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper, giving this 8R SUV a large multi-piston pad footprint for repeated high-energy stops.
- The rear package uses TTSPORT EP4 4-Piston Calipers with EPB on 380mm rotors, so the Q5 / SQ5 keeps electronic parking-brake function while adding rear thermal capacity.

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 axle uses the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper, a 10-piston OEM-derived Audi RS caliper selected for even pad loading, strong clamping distribution, and a firm pedal under repeated braking. Its Akebono provenance matters on the Q5 / SQ5 8R because the caliper is not a generic aftermarket casting; it is a genuine high-performance Audi application adapted with StopFlex trim-specific brackets, hats, and hardware. The 420mm carbon-ceramic rotor gives the caliper the thermal mass and swept area needed for a heavy all-wheel-drive SUV.
Rear Caliper (Balance)
The rear axle uses the TTSPORT EP4 4-Piston Caliper with EPB on a 380mm carbon-ceramic rotor to add rear brake capacity without deleting the factory electronic parking brake. Its four hydraulic service pistons support rear-axle braking stability, while the dedicated EPB actuator piston preserves the parking-brake function expected on the 8R Q5 / SQ5.
Front & rear, engineered together: StopFlex engineers the 420mm front and 380mm rear package as one system so brake bias, rotor-hat offset, caliper mounting, and line routing are matched to the confirmed Q5 or SQ5 trim. That matters more than a front-only conversion on this chassis because the rear EPB caliper must preserve OE parking-brake behavior while contributing real rear 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 my exact Q5 or SQ5 8R trim?
StopFlex does not treat all 8R cars as identical. Before production, your model year, Q5 or SQ5 trim, hub and knuckle configuration, wheel specs, and clearance data are confirmed so the brackets, rotor hats, offsets, and caliper mounting match your exact car.
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; spoke shape, barrel profile, offset, and caliper face clearance must be checked against the Genuine Akebono OEM Audi RS 10-Piston (10N) Caliper before the kit is built.
Will the electronic parking brake still work?
Yes. The rear package uses the TTSPORT EP4 4-Piston Caliper with EPB, which has four hydraulic service pistons for braking and a dedicated EPB actuator piston for parking-brake function, so the 8R Q5 / SQ5 keeps OE-style EPB convenience.
Why choose carbon-ceramic rotors instead of another iron big-brake kit?
On a Q5 or SQ5 8R, carbon-ceramic rotors reduce unsprung rotating mass, cut visible brake dust, and tolerate repeated high-temperature stops better than conventional iron rotors. This is most useful for hard street driving, mountain use, towing-light loads within the vehicle’s limits, and occasional track work where heat recovery matters.
