Bosch BD901 Brake Discs - Rear Axle - 1 single brake Disc

Bosch BD901 Brake Disc – Rear Axle

The Bosch BD901 Brake Disc is a high‑performance, single rear brake disc designed for optimal stopping power and durability in a wide range of passenger vehicles. Manufactured by Bosch, one of the world’s leading automotive component suppliers, this disc delivers reliable braking performance under both everyday driving conditions and more demanding scenarios.

Key Features

• Solid Construction: The BD901 is a solid (full) brake disc, offering excellent heat dissipation and resistance to warping. This design ensures consistent braking performance even during prolonged use.
• Optimal Size: With an outer diameter of 240 mm and a thickness that balances strength with weight, the disc fits a broad range of rear brake systems without compromising vehicle dynamics.
• High‑Quality Material: Crafted from premium alloy steel, the disc provides superior wear resistance and maintains structural integrity across temperature extremes.
• Precision Machining: Each disc is machined to tight tolerances, guaranteeing a perfect fit on the hub and rotor assembly. This precision reduces vibration and enhances overall braking feel.
• Compatibility: The BD901 is engineered to match Bosch’s rear brake systems for numerous models, ensuring seamless integration with existing calipers and pads.

Performance Characteristics

The disc’s solid construction allows it to absorb and dissipate heat efficiently. This reduces the risk of brake fade, a common issue in high‑temperature environments or during aggressive driving. The alloy steel composition also contributes to a lower overall weight, which can improve vehicle handling by reducing unsprung mass.

Installation Overview

Installing the BD901 involves mounting it onto the rear hub and securing it with the appropriate fasteners. Because the disc is solid, there are no internal passages for fluid or air; this simplifies installation compared to drilled or slotted designs. The disc’s dimensions match standard Bosch caliper mounts, allowing technicians to replace it without extensive modifications.

Maintenance Tips

• Regular Inspection: Check the disc for signs of wear, scoring, or glazing during routine brake inspections. Early detection prevents uneven pad wear and maintains braking efficiency.
• Proper Pad Selection: Pair the BD901 with compatible Bosch brake pads to ensure optimal friction characteristics and avoid premature wear.
• Avoid Overheating: While the disc is designed for high heat tolerance, extreme temperatures can still affect performance. Use appropriate driving techniques in hot conditions to preserve braking integrity.

Applications

The BD901 is suitable for a variety of rear brake systems across multiple vehicle platforms. Its size and construction make it an ideal choice for:

• Passenger cars requiring reliable, everyday braking performance.
• Light commercial vehicles where durability under load is essential.
• Performance-oriented models that demand consistent stopping power during spirited driving.

Why Choose Bosch BD901?
