Brembo 09.B436.51 - Brake Disc

Brembo 09.B436.51 Brake Disc

The Brembo 09.B436.51 is a high‑performance front brake disc designed for the Mercedes‑Benz A‑Class, B‑Class, CLA, and GLA models. It combines advanced materials, precise engineering, and a distinctive UV coating to deliver exceptional stopping power, durability, and aesthetic appeal.

Key Technical Specifications

• Diameter: 295 mm (11.6 in)
• Thickness: 28 mm (1.10 in) at the outer edge, 51 mm (2.01 in) overall height
• Material Composition: High‑carbon steel with a proprietary alloy for improved heat dissipation and wear resistance.
• Ventilation: Internal venting pattern enhances airflow, reducing brake fade during high‑temperature operation.
• Pitting Pattern: Precision‑drilled holes provide uniform cooling while maintaining structural integrity.
• Coating: UV‑resistant finish that protects against corrosion and preserves the disc’s appearance over time.

Design Features & Performance Benefits

The 09.B436.51 incorporates several design elements that elevate its performance:

• High‑Carbon Alloy: The steel alloy is engineered to withstand extreme temperatures, ensuring consistent braking force even under aggressive driving conditions.
• Internal Venting: By channeling air through the disc’s interior, heat is efficiently dissipated, preventing brake fade and maintaining optimal friction levels.
• Precision Drilling: The drilled pattern not only aids cooling but also reduces overall weight, contributing to improved vehicle dynamics.
• UV Coating: This protective layer resists oxidation and UV degradation, extending the disc’s service life while keeping it visually pristine.
• Compatibility: Designed specifically for the front wheel assemblies of Mercedes‑Benz A‑Class (W176), B‑Class (W242), CLA (C117), and GLA (X156) models, ensuring a seamless fit with existing calipers and hardware.

Installation & Maintenance Guidelines

Proper installation and routine maintenance are essential to maximize the lifespan and performance of the 09.B436.51. Follow these best practices:

• Pre‑installation Check: Inspect the disc for any manufacturing defects such as cracks or uneven drilling before mounting.
• Caliper Compatibility: Verify that the calipers are compatible with the disc’s thickness and diameter. Use OEM or equivalent brake pads to maintain optimal contact pressure.
• Tightening Sequence: Tighten the mounting bolts in a star pattern, gradually increasing torque to the manufacturer’s specified value to avoid warping.
• Bake‑Out Procedure: After installation, perform a brake bake‑out by driving at moderate speeds for several minutes. This helps eliminate any residual moisture and ensures proper pad seating.
• Regular Inspection: Check the disc surface for glazing or uneven wear every 10,000 km (or as recommended by the vehicle manufacturer). Replace if the thickness falls below the minimum safe limit.

Applications & Vehicle Compatibility

The Brembo 09.B436.51 is engineered for a range of Mercedes‑Benz models, providing consistent performance across different vehicle platforms:

• A‑Class (W176): Front discs for both sedan and hatchback variants.
• B‑Class (W242): Suitable for the compact SUV body style.
• CLA Coupe (C117): Fits the sporty coupe’s front wheel architecture.
• GLA (X156): Designed for the crossover’s front suspension layout.
