High-Strength CNC Machined Brake Pedal Bracket in 6061-T6 Aluminum Alloy for Motorcycles

This lightweight high-strength brake pedal bracket is a core load-bearing component of the braking system customized for high-performance motorcycles and off-road vehicles. With an integrated hollow mechanical structure, it undertakes the installation fixation, force transmission and stroke limit functions of the brake pedal, perfectly adapting to the harsh working conditions of high-speed motorcycle driving and high-frequency braking. It is widely used in the rear brake system upgrade of street bikes, supersport bikes, off-road motorcycles and other models, providing riders with stable, precise braking feedback and structural safety guarantee.

Core Material: 6061-T6 Aluminum Alloy (benchmark material for motorcycle modified parts, adapting to the lightweight and impact resistance requirements of this part)

Key Performance:

• Tensile strength ≥310MPa, yield strength ≥276MPa, with extreme impact resistance, fatigue resistance and bending resistance, can withstand instantaneous large loads brought by high-frequency braking
• Density is only 2.7g/cm³, greatly reducing unsprung mass while ensuring structural rigidity, improving vehicle handling response and acceleration performance
• Natural corrosion resistance, adapting to outdoor, humid and dusty riding environment, fully complying with RoHS and REACH environmental protection standards
• Extremely strong dimensional stability, no creep or deformation during long-term use, ensuring the consistency of brake stroke and braking safety

This part adopts 5-axis linkage CNC high-speed precision milling process, integrally cutting and forming from a solid 6061-T6 aluminum bar, completely avoiding the hidden danger of structural strength caused by welding/casting.

• Core processes: large-area hollow weight reduction milling, complex special-shaped contour processing, high-precision mounting hole/pin hole boring, anti-slip tooth pattern rolling forming
• Auxiliary processes: high-gloss contour chamfering, deburring, surface sandblasting oxidation treatment, ensuring no sharp edges and stress concentration
• Full CNC programming, one-time clamping forming, ensuring the consistency of geometric tolerances and structural strength of each mounting hole

Machining Accuracy:

• Dimensional tolerance: ±0.015mm, strictly matching the assembly clearance of brake pedal and pin shaft
• Geometric tolerance: coaxiality of mounting hole ≤0.02mm, flatness of load-bearing surface ≤0.03mm
• Surface roughness: Ra≤1.6μm, smooth and burr-free load-bearing surface, improving structural stability

Usage Requirements:

• Adapt to a wide temperature riding environment of -40℃~85℃, can withstand instantaneous braking load ≥2000N and high-frequency impact
• No deformation or cracking during long-term use, ensuring accurate brake stroke and linear braking feedback
• Clean the hole position before installation to avoid impurities affecting the flexibility of pin shaft rotation and braking safety

With heat treatment, adopting T6 solution aging strengthening process.

• Core purpose: completely eliminate processing internal stress, greatly improve material strength and hardness, enhance fatigue and impact resistance, avoid structural deformation under high-frequency braking, and ensure long-term reliability of the brake system.

Natural color sandblasting oxidation treatment, retaining the original metallic texture of aluminum alloy.

• Process advantages: form a dense and wear-resistant oxide protective layer, significantly improve surface corrosion resistance, scratch resistance and stone impact resistance, matte texture combines aesthetics and practicality, adapting to the appearance requirements of motorcycle modification, fully meeting environmental protection requirements.

Implement a full-process closed-loop quality control system, strictly complying with ISO9001 quality standards and motorcycle parts industry specifications:

• Raw material incoming: spectral material inspection to ensure 100% compliance of 6061-T6 alloy composition and mechanical performance
• Processing process: 100% geometric tolerance inspection, real-time monitoring of mounting hole accuracy and structural integrity
• Final product inspection: appearance defect inspection, load impact test, full dimensional inspection, traceable inspection report for each batch
• Pre-delivery: cleanliness inspection to ensure no iron chips and impurities in the hole position and tooth pattern, meeting motorcycle assembly requirements
