• Being a world leading professional brake parts manufacturer, Winhere produces more than 55 million units of brake discs and 10 million sets of brake pads annually for OEM and IAM. 

• 96%+ car park coverage of brake discs and brake pads from A to Z for both passenger cars and commercial vehicles. 

• IATF16949, ISO14001, ISO45001, ECE R90, CNAS certificated. 

• National Green Manufacturer and China’s Champion Enterprise awarded by M.I.I.T. and C.F.I.E. 

• National Standard of “Brake Disc for Automobile” GB/T 34422-2017 is led by National Quality Supervision and Inspection Center for automobile parts, Winhere is the responsible drafting company for this national standard.

Brake Discs Features:                                                   

•Equivalent to OE design 

G3000 / GG15HC high-carbon grey iron builds a stable transfer film with semi-met's steel/iron content; the film is what keeps μ predictable, so disc chemistry must be specified — a low-grade blank breaks the pad's R90 curve.

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

Brake Pads Features:

•High performance 

•Long-life service 

•Anti-fade 

•Low noise, low dust 

•Environmental friendly

•Taxi, delivery van, caravan/trailer towing, mountain-road fleets — semi-met's stable hot μ and rotor "true-up" make pad+disc cost per 10k km lowest on routes where ceramic fades.

Steel-fibre content is the defining variable, not "semi-metal" as a label:

•Semi-metallic means 30–70% metallic loading (chopped steel fibre + reduced iron powder + Cu), versus low-steel ≤20% and NAO <10%. The exact steel/fibre ratio is tuned per axle load, not a one-size compound — that is where semi-met wins over ceramic for heavy duty.

• 100% critical dimensions, runout and DTV inspection 

• Material physical and chemical inspection

• Test shear strength, compressibility, density, flatness and parallelism 

• Test performance and noise/NVH
