Installation & Compatibility: 9424212112 Cv Vented Brake Disc

This brake disc requires precise installation and vehicle-specific compatibility verification to ensure optimal braking performance.

Installation Steps

1. Vehicle preparation

• Park on flat ground. Engage parking brake. Use wheel chocks.

• Gather tools: hydraulic jack, torque wrench, breaker bar.

2. Wheel removal

• Lift vehicle with jack. Secure on axle stands.

• Remove lug nuts. Detach wheel.

3. Caliper disassembly

• Unbolt caliper bracket (2 bolts).

• Hang caliper with wire hook. Avoid stressing brake line.

4. Old rotor removal

• Tap rotor edges with rubber mallet.

• Rotate while pulling to release from hub.

5. Surface preparation

• Clean hub surface. Remove rust and debris.

• Wipe with brake cleaner.

6. New rotor mounting

• Align rotor with hub studs.

• Secure with original lug nuts temporarily.

7. Caliper reassembly

• Reinstall caliper bracket. Torque bolts to 90 N·m.

• Verify caliper piston retraction.

8. Wheel remounting

• Reattach wheel. Hand-tighten lug nuts in star pattern.

• Lower vehicle. Final torque: 120 N·m.

9. Brake system test

• Pump brake pedal 5-6 times until firm.

• Conduct low-speed test (under 30 km/h).
