Key Features & Advantages

 

■ High‑Performance Friction Formula

100% asbestos‑free, compliant with EU environmental regulations.

•Stable friction coefficient (0.4–0.45) across −40°C to 600°C, minimal thermal fade.

•Balanced hardness: gentle on brake discs, reduces wear and extends disc life.

 

■ Structural & Material Design

High‑strength steel backing plate with precision stamping and anti‑corrosion coating.

Integrated wear indicator (mechanical/electronic) for timely replacement alerts.

Noise‑damping shim eliminates brake squeal, improves NVH performance.

Thermal‑resistant adhesive ensures no delamination under heavy braking.

Notes on Replacing WVA 21958 Brake Pads?

  • Must be used with brake discs of the same specification (approx. Ø 430–436 mm).
  • A running-in period of 200–300 km is required after replacement (avoid hard braking).
  • Inspect the brake caliper, guide pins, dust boots, and shims.
  • Tighten the bolts to the standard torque of approx. 180–220 N·m.
