2025-2026+ Xiaomi YU7 Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2025-2026+ Xiaomi YU7 is a heavy 800V EV SUV, so repeated high-speed stops put more heat into the front discs than a single 100-0 km/h spec shows. This StopFlex OEM-size carbon-ceramic kit is built around the YU7 rotor references on this page: 355mm or 400mm front and 345mm or 380mm rear, with pads, hats, and floating hardware matched to the selected factory-size setup. The payoff is lower rotating mass, less brake dust on the YU7’s open wheels, and better thermal stability while retaining the OEM caliper architecture when the ordered rotor size matches the car.
- Built only for the listed YU7 OEM-size brake references: 355mm or 400mm front rotors with 345mm or 380mm rear rotors.
- The YU7 Max family is associated with 4-piston fixed Brembo front calipers; rotor diameter and caliper clearance must be confirmed before ordering.
- Carbon-ceramic discs reduce iron-rotor dust and unsprung mass on a 2,300kg-plus electric SUV that can reach 240-253 km/h depending on trim.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Xiaomi YU7 |
| Model years | 2025-2026+ |
| Front rotor reference | YU7: 355mm, 400mm |
| Rear rotor reference | YU7: 345mm, 380mm |
| 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 2025-2026+ Xiaomi YU7?
No. This page is limited to the exact YU7 trims and rotor sizes listed here: 355mm or 400mm front and 345mm or 380mm rear. Confirm your VIN, trim, front and rear rotor diameter, and wheel size before ordering.
Does the kit keep the factory calipers and electronic parking brake?
This is an OEM-size replacement kit, not a caliper conversion. It is designed to work with the matching factory caliper setup and rear EPB hardware when the YU7 rotor hat, offset, pad shape, and parking-brake interface match the selected StopFlex spec.
Why change from the YU7 factory iron brakes to carbon ceramic?
The main reasons are heat control, lower rotating mass, and cleaner wheels. On a high-output EV SUV, carbon-ceramic rotors handle repeated hard stops with less thermal distortion than iron and produce far less visible brake dust.
What should I measure before buying the 355/345mm or 400/380mm setup?
Measure the actual front and rear rotor diameters, confirm whether your car uses the standard 4-piston fixed caliper or the Max Brembo package, and check inner wheel barrel clearance. Do not order from model year alone.
