Bosch BD28 Brake Discs - Front Axle - ECE-R90 Certified - 1 Set of 2 Discs

Bosch BD28 Brake Discs – Front Axle

The Bosch BD28 Brake Disc set is engineered to deliver exceptional stopping power and durability for front‑axle applications. Designed with a focus on performance, safety, and longevity, this disc set meets the stringent ECE-R90 certification, ensuring compliance with European emission and safety standards.

Key Technical Specifications

• Diameter: 239 mm – a size that balances braking efficiency with vehicle dynamics for a wide range of passenger cars.
• Thickness: 20 mm – provides robust structural integrity while maintaining optimal heat dissipation.
• Ventilation: Internal venting system – reduces heat buildup, minimizes brake fade, and extends component life.
• Hub Bore: 100 mm – compatible with standard front‑axle hubs on many European vehicles.
• Material Composition: High‑grade cast iron alloy reinforced with steel inserts for enhanced wear resistance.

Design Features That Enhance Performance

The BD28 disc incorporates a meticulously engineered internal venting pattern, which channels heat away from the friction surface. This design not only improves braking consistency during prolonged use but also reduces the risk of brake fade in high‑temperature scenarios such as hill climbs or spirited driving.

Its smooth, flat surface finish ensures optimal contact with brake pads, allowing for even pad wear and consistent stopping force across the entire disc circumference. The precision machining guarantees that each disc meets Bosch’s strict tolerance standards, resulting in reliable performance from the first use.

Compatibility and Fitment

The BD28 set is engineered to fit a broad spectrum of front‑axle vehicles, particularly those within the Volkswagen, Audi, Seat, and Skoda families. Its standardized dimensions make it an ideal replacement for original equipment discs on models such as:

• Volkswagen Golf (various generations)
• Audi A3, A4, and related compact cars
• Seat Ibiza, León, and similar hatchbacks
• Skoda Octavia, Fabia, and other front‑wheel drive platforms

Because the set includes two discs—one for each side of the axle—it is ready for immediate installation without the need for additional components.

Installation Guidelines

1. Remove existing discs: Carefully detach the current brake discs, noting any retained hardware such as retaining screws or clips.
2. Clean the hub: Ensure the hub surface is free of rust, debris, and old grease to guarantee a secure fit.
3. Align the new disc: Position the BD28 disc onto the hub, aligning it with the mounting holes. Use a torque wrench to tighten the retaining bolts to Bosch’s specified values.
4. Check brake pad clearance: Verify that the new discs allow sufficient clearance for the brake pads and calipers.
5. Reassemble the braking system: Reinstall all components, including caliper brackets, brake lines, and any associated hardware.

Maintenance Tips

• Inspect discs regularly for signs of wear such as uneven thickness or surface glazing.
• Replace brake pads when pad wear indicators reach the minimum threshold to maintain optimal contact with the disc surface.
• Keep the braking system clean; remove any debris that could compromise heat dissipation.
