Technical Specifications

Installation Guidelines

1. Preparation: Ensure the vehicle’s rear suspension is securely lifted and supported. Remove any existing drum or damaged components.
2. Alignment: Position the new drum onto the hub, aligning it with the mounting flange. Verify that the drum sits flush against the brake shoes.
3. Bolt Securing: Tighten all mounting bolts to the manufacturer’s torque specifications, typically around 120 Nm, using a calibrated torque wrench.
4. Brake Shoe Adjustment: Install or replace rear brake shoes as needed. Adjust shoe position so that they contact the drum evenly without excessive clearance.
5. System Check: Reconnect any ABS sensors and perform a low‑speed test drive to confirm proper operation and absence of vibration.

Maintenance Tips

• Inspect the drum surface for scoring or glazing every 10,000 km. Replace if wear exceeds manufacturer limits.
• Check brake shoe wear regularly; replace shoes before they become too thin to maintain effective braking.
• Keep the drum clean from debris and brake dust to prevent corrosion and ensure optimal heat transfer.
• Verify ABS sensor functionality after any major repair or replacement to avoid system faults.
