WVA19094 E‑mark Certificated K8 Material Truck Brake Lining
Definition: WVA19094 truck brake lining with E‑mark certification and K8 friction material, for heavy‑duty commercial vehicles
1. WVA19094 Core Part Number
WVA: Code issued by European Friction Materials Association. It is a universal industry code for brake linings, used for vehicle matching, dimension and mounting reference, widely adopted in global auto‑parts trade.
WVA19094: Heavy‑duty drum brake lining for trucks and semi‑trailers. It refers to large‑size drum brake shoe linings, not disc brake pads.
Application Fitment: Mainly for European heavy‑duty brands including MAN, IVECO, DAF, tractors and trailer axles.
WVA number is used to verify lining length, width, thickness and rivet hole positions. It is the top reference for purchasing, foreign trade and quality inspection.
2. E‑mark Certificated
E‑mark stands for ECE R90 certification, mandatory EU regulation for brake components. Truck brake linings exported to EU must obtain valid ECE R90 E‑mark certificate, otherwise customs clearance and road use are prohibited.
Key notes:
The certificate must cover WVA19094, with verifiable certificate number and E‑mark country code (E1/E4/E11 etc.).
R90 compliance requirements: stable friction coefficient, high‑temperature fade resistance, wear rate, shear strength, asbestos‑free formulation, low noise and qualified braking distance.
Foreign trade tip: Marking "E‑mark certificated" alone is insufficient. Buyers usually request certificate number and test reports. Counterfeit certificates bring high business risks.
Non‑EU markets: Clients from Middle East, Africa also accept E‑mark as quality proof.
3. K8 Material
K8 is a well‑known semi‑metallic friction material grade for commercial drum brake linings, widely used in European heavy‑duty vehicles.
Performance Features of K8 Material
Stable friction coefficient: Minor friction fluctuation under varying temperatures, excellent anti‑fade performance under heavy‑load and long‑downhill braking conditions. Ideal for heavy‑duty truck application.
Service life: Medium‑to‑high wear resistance, longer service life than economy‑grade K5 / K6 materials.
Counter‑part friendly: Gentle wear behaviour against brake drums, reduces abnormal drum damage.
Noise performance: Good anti‑squeal effect under heavy‑load braking.
Operating conditions: Long‑haul highway trucks and trailers with frequent heavy‑load braking.
Grade comparison: K5 = economy for light‑duty short‑haul; K6 = medium grade; K8 = mid‑high grade for heavy‑duty; K9 = premium grade for harsh mining working conditions. ⚠️ K8 is an industry customary grade rather than official standard. Formulas vary among manufacturers. Confirm friction coefficient range (normally 0.35‑0.45) during procurement.
4. Truck Brake Lining
Brake Lining: Drum brake lining, to be riveted onto brake shoe.
Brake Pad: Disc brake pad. Avoid terminology confusion in foreign trade documents.

6. Common Risks & Buyer Concerns
Multiple shoe‑back versions exist for WVA19094. Same WVA number may come with different rivet hole layouts. Drawings or physical samples are required for order confirmation.
E‑mark certificate: Make sure WVA19094 is listed within the certificate scope. Many manufacturers' certificates only cover partial WVA numbers.
K8 is a common trade name. Buyers may ask for friction material test reports for performance verification.
Asbestos‑free statement is required for European customers.
