Technical Specifications

Installation Guidelines

1. Preparation: Ensure the vehicle is securely lifted and supported. Remove existing brake components, including shoes and hardware.
2. Alignment Check: Verify that the drum’s mounting surface aligns with the axle housing. Use a torque wrench to tighten mounting bolts to the specified torque (typically 70–80 Nm).
3. Brake Shoe Installation: Install new brake shoes, ensuring proper fit and clearance. Adjust shoe position according to manufacturer specifications.
4. Reassembly: Reinstall all hardware, including springs, pins, and retaining clips. Verify that the drum rotates freely without binding.
5. Brake System Check: Bleed the brake system to remove air bubbles, then test braking performance at low speeds before normal operation.

Maintenance Tips

• Inspect the drum surface for scoring or glazing every 10,000 km. Replace if wear exceeds manufacturer limits.
• Clean the drum with a non‑abrasive cleaner to remove brake dust and debris.
• Check the hole pattern regularly; ensure no obstructions that could impede heat dissipation.
• Replace any damaged mounting bolts or hardware promptly to maintain structural integrity.
