Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2009-2017 Audi Q5 / SQ5 (8R). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2009-2017 | Akebono OEM Audi S 6-Piston (8N) Caliper / 380mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 19" |
Every StopFlex kit is bespoke-engineered for your exact model and trim — brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, never assumed from the platform. Trims that share a chassis name can differ mechanically: a pure performance variant often carries different knuckles, hub geometry, and wheel ET clearance than the standard models, so parts that bolt onto one are not the parts that fit the other. Calipers, pads, rotor hats, floating hardware, and brake lines ship as one matched system built to your confirmed trim. Modified knuckles, uprights, or non-factory suspension mounting points must be reviewed before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |

Why Carbon Ceramic — and Why StopFlex
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Winter & Cold-Weather Braking
Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.
Caliper Overview
Front Caliper
The Akebono OEM Audi S 6-Piston (8N) Caliper is the same monoblock 6-piston front unit Audi fitted to its S models, so you get OE clamping consistency and predictable pedal feel over the 380mm rotor rather than a generic aftermarket casting. It bolts to a bracket cut for your confirmed 8R trim.
Rear Caliper
The TTSPORT EP4 4-Piston Forged Caliper adds real rear-axle thermal capacity with four 28mm hydraulic service pistons, while a dedicated 27mm EPB actuator piston keeps your factory electronic parking brake working. Its two-piece forged-aluminum body weighs about 4.50 kg per caliper without pads and clears 18 in wheels and up.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.

FAQ
Will this kit clear my wheels?
The front rotor is 380mm, so you need at least a 19-inch wheel to clear it, and spoke shape matters as much as diameter. The rear TTSPORT EP4 clears 18 inches and up, but your build is governed by the larger front, so plan on 19s minimum. Send us your exact wheel and offset and we'll confirm caliper and spoke clearance before you buy.
How does this perform on cold winter mornings?
Physics is honest here: an untuned cold carbon-ceramic disc bites a little less than cold iron on the first stops. We tuned both the pad compound and the disc's ceramic coating for cold starts, so first-stop feel now comes very close to summer feel. On the coldest mornings we still recommend a little extra following distance for the first few stops until everything is up to temperature.
Is this really made for my SQ5, not just the Q5 platform?
Every kit is bespoke-engineered for your confirmed trim. The SQ5 can differ from a base Q5 in knuckle, hub geometry, and wheel ET clearance, so we cut the brackets, set the rotor-hat offsets, and match the Akebono 8N caliper mounting to your exact car. We do not make a platform-wide bolt-on claim; we build to the VIN and trim you confirm.
Will my electronic parking brake still work?
Yes. The 8R uses a factory electromechanical parking brake, and the rear TTSPORT EP4 caliper has a dedicated EPB actuator piston that preserves that function. You keep the OE dash-switch parking brake and hill-hold behavior while gaining rear-axle thermal capacity from the four hydraulic service pistons.
