Products

Brake Discs Features:

•Equivalent to OE design

•Smooth and quick stop

Adopts micron-level tolerance control, non-directional symmetrical structure design, no need to distinguish left and right for installation. Dynamic balance precision calibration corrects disc eccentricity error in full volume, minimizing brake judder under heavy load, high speed and mountain road conditions. Full-process quality inspection ensures batch stability and consistency for EV bulk orders.

•Anti-rust

•Low noise, low dust

The friction surface adopts ultra-precision mirror grinding process, with extremely flat surface and uniform friction fit with EV special brake pads. It effectively suppresses high-frequency braking howling and low-speed stuttering noise.

Adopts upgraded multi-layer anti-rust coating and integral passivation treatment. All non-friction surfaces are fully covered with protective layers without dead ends.

•Optimal thermal performance

Brake Pads Features:

•High performance

•Long-life service

•Anti-fade

•Low noise, low dust

•Environmental friendly

Perfectly adapts to EV exclusive working scenarios: frequent kinetic energy recovery braking, urban congested start-stop, high-speed long-distance driving, mountain road continuous downhill, coastal high salt fog, high temperature and humid climate, fully meeting global multi-region road and weather environment requirements.

Product Positioning:

E-car Composite Front Brake Discs are specially upgraded composite brake rotors tailored for new energy electric vehicles. EVs feature heavier curb weight, instant torque output, higher daily average speed and frequent kinetic energy recovery braking compared with traditional fuel cars, which puts forward stricter requirements on brake disc heat resistance, deformation resistance and stability.

Core Material & Technical Parameters:

•High-Strength Composite Casting Material

Adopts OE-level G3000 high-carbon alloy composite cast iron customized for new energy vehicles, with optimized carbon-silicon alloy ratio.The composite formula effectively resists thermal fatigue cracks caused by frequent EV kinetic energy braking, avoiding disc cracking and failure after long-term high-load operation.

•Lig htweight Optimization Data

Compared with traditional full heavy-duty brake discs of the same specification, the composite structure realizes reasonable weight reduction without sacrificing rigidity. Optimized unsprung mass reduces vehicle inertial load, effectively improving steering response and driving control.

•Size & Installation Standard

100% equivalent OE original design, strictly follows EV front brake disc installation parameters.Multiple mainstream specifications are available, with precise hole position, center aperture, thickness and offset data. No modification, no drilling, perfect direct replacement for original factory parts, compatible with automated assembly and aftermarket quick replacement.

Applicable EV Models & Working Conditions:

•Applicable EV Models & Working Conditions

Widely compatible with global mainstream new energy electric vehicles: Tesla Model 3/Y/S/X, BYD Han/Tang/ATTO 3, Xpeng P7/G6/G9, NIO ET5/ET7/ES6, Li Auto L7/L8/L9, Volkswagen ID series, Hyundai/Kia EV series, and other electric sedans, electric SUVs and light electric commercial vehicles.
