Bosch BD1120 Discs with bearing - Rear Axle - ECE-R90 Certified - 1 single brake Disc

Bosch BD1120 Rear Axle Brake Disc

The Bosch BD1120 is a high‑performance brake disc designed for the rear axle of commercial and light commercial vehicles such as Renault Trafic, Opel Vivaro, Vauxhall, Nissan, and others. It meets the stringent ECE‑R90 certification, ensuring compliance with European safety standards for vehicle braking systems.

Key Technical Specifications

• Diameter: 280 mm (Ø280 mm)
• Thickness: 12.5 mm
• Weight: Approximately 1.8 kg per disc
• Material Composition: High‑strength steel alloy with a hardened surface for superior wear resistance.
• Bearing Integration: Built‑in bearing (BD1120) allows the disc to rotate smoothly, reducing friction and heat buildup during braking.
• ABS Sensor Compatibility: Integrated sensor ring compatible with ABS systems on supported models.

Design Features & Performance Benefits

The BD1120 incorporates several engineering features that enhance braking performance and durability:

• Optimized Heat Dissipation: The disc’s cross‑sectional design promotes efficient heat transfer, preventing brake fade during heavy or repeated use.
• Low Rotational Mass: A lighter disc reduces the load on the braking system, improving response times and reducing wear on pads.
• Pre‑lubricated Bearing: The bearing is pre‑lubricated with high‑temperature grease, ensuring reliable operation from installation without additional maintenance.
• Robust Edge Geometry: A slightly beveled edge improves pad contact and reduces the risk of glazing or uneven wear.

Compatibility & Vehicle Applications

The disc is engineered to fit a wide range of rear axle configurations. Common vehicle models that accept the BD1120 include:

• Renault Trafic (2001‑2014)
• Opel Vivaro A (X83) and Combi variants
• Nissan NV series
• Vauxhall Corsa, Vectra, and other light commercial models

It is available in both single‑disc and dual‑disc configurations, depending on the vehicle’s braking system layout.

Installation & Maintenance Guidelines

1. Removal: Use a torque wrench to loosen the wheel hub bolts. Carefully lift the wheel assembly and remove the old disc.
2. Inspection: Check the hub surface for scratches or damage before installing the new disc.
3. Installation: Place the BD1120 onto the hub, ensuring proper alignment with the bearing housing. Tighten bolts to the manufacturer’s specified torque sequence.
4. Brake Pad Compatibility: Pair the disc with compatible brake pads that match the disc’s diameter and thickness for optimal performance.
5. Break‑In Procedure: Perform a gentle braking test after installation to allow the pad material to seat correctly on the new disc surface.

Quality Assurance & Certification

The BD1120 is produced under Bosch’s rigorous quality control processes. It carries the ECE‑R90 certification, confirming that it meets European safety and performance standards for commercial vehicle braking systems.
