Bosch BD1227 Brake Discs - Front Axle - ECE-R90 Certified - 1 Set of 2 Discs

Bosch BD1227 Brake Discs – Front Axle

The Bosch BD1227 is a premium front‑axle brake disc set designed for high performance and durability. Each set contains two discs, one for the left wheel and one for the right, ensuring balanced braking across the vehicle’s front axle.

Key Features

• ECE‑R90 Certified: Meets stringent European safety standards for brake performance and reliability.
• Vented Design: Integrated ventilation channels dissipate heat efficiently, reducing the risk of brake fade during prolonged use.
• High‑Carbon Composite Layer: Enhances wear resistance while maintaining a lightweight profile, contributing to overall vehicle efficiency.
• Precision Machining: Each disc is manufactured with tight tolerances to ensure smooth operation and consistent braking feel.
• Compatibility: Specifically engineered for the Mercedes‑Benz C‑Class (W204, S204, C204) and related models, but also fits a wide range of other vehicles that require a 295 mm diameter disc.

Technical Specifications

Performance Benefits

The combination of a vented structure and high‑carbon composite coating delivers several performance advantages:

• Consistent Braking Force: Even heat distribution keeps the brake pads within optimal temperature ranges, ensuring reliable stopping power.
• Reduced Wear: The composite layer resists abrasive forces from brake pads, extending disc life and reducing maintenance frequency.
• Lightweight Construction: Lower unsprung mass improves handling dynamics and fuel efficiency.
• Noise Reduction: Smooth surface finish minimizes squeal and chatter during braking.

Installation Guide

1. Secure the vehicle on a stable lift or jack stands, ensuring the front wheels are free to rotate.
2. Remove the existing brake discs by loosening the caliper bolts and sliding the disc out of the wheel hub.
3. Clean the hub surface with isopropyl alcohol to remove any grease or debris.
4. Place the new Bosch BD1227 disc onto the hub, aligning it with the mounting flange.
5. Tighten the mounting bolts to the manufacturer’s torque specification (typically 80–90 Nm).
6. Reinstall the brake caliper and ensure the pads are seated correctly against the new discs.
7. Repeat the process for the opposite wheel.
8. Perform a brake fluid bleed if necessary, then test the braking system at low speed to confirm proper operation.

Maintenance Tips

• Inspect discs regularly for signs of glazing or uneven wear; replace if damage exceeds manufacturer guidelines.
• Keep the disc surface clean from brake dust and road grime to maintain optimal heat transfer.
• Use high‑quality brake pads compatible with vented discs to preserve performance characteristics.
