2023-2026+ NIO ET5T Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2023-2026+ NIO ET5T Carbon Ceramic Brake Kit — OEM-Size Replacement
The ET5T is a 2,200+ kg dual-motor wagon, so repeated high-speed stops can put more heat into the 355 mm front and 330 mm rear OEM-size brake package than normal street driving ever will. This StopFlex OEM Replacement kit keeps the factory 4-piston fixed-caliper layout and rotor diameters while replacing the iron friction rings with carbon-ceramic rotors, matched pads, hats, and floating hardware for lower brake dust, reduced rotating mass, and more stable hot-stop behavior.
- Built around the ET5T rotor references listed for this page: 355 mm front and 330 mm rear, not a generic ET5/ET5T big-brake conversion.
- Designed for the ET5T factory high-performance 4-piston fixed-caliper brake system, so the upgrade targets rotor material, pad match, hats, and floating hardware rather than changing caliper geometry.
- Carbon-ceramic friction rings help reduce the visible iron dust and corrosion that stand out on the ET5T’s open wheel designs, while cutting rotating mass at all four corners.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | NIO ET5T |
| Model years | 2023-2026+ |
| Front rotor reference | ET5T: 355mm |
| Rear rotor reference | ET5T: 330mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 18" (for the 355 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 355 mm rotor, so the minimum wheel size is 18". Wheels under 18" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
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.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
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.

FAQ
Will this kit fit every 2023-2026+ NIO ET5T?
No. This page is only for ET5T configurations that use the 355 mm front and 330 mm rear OEM rotor sizes listed here with the factory 4-piston fixed calipers. Confirm your rotor diameters, caliper type, model year, and wheel clearance before ordering.
Does the kit keep the ET5T electronic parking brake and auto-hold functions?
The kit replaces rotors, pads, hats, and floating hardware only. It does not convert the rear parking-brake system, so EPB and auto-hold compatibility depends on matching the correct ET5T rear rotor and pad specification for the 330 mm rear setup.
Why use carbon-ceramic rotors instead of another OEM iron replacement?
For an ET5T owner, the main reasons are lower brake dust, less unsprung and rotating mass, and better resistance to heat-related fade during repeated hard stops. The 355/330 mm OEM-size format preserves the factory brake balance instead of moving to an oversized BBK.
Is this better for daily driving or track use?
This is an OEM-size carbon-ceramic replacement for street-driven ET5T cars that also see repeated high-speed braking, mountain driving, or occasional performance use. Pad selection and bedding matter; confirm your intended use so the pad compound matches cold response, noise tolerance, and heat demand.
