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.
