Brake Disc Front Optra / New Optra [HIQ]

This document details the functional and material specifications for the HIQ Front Brake Disc, specifically engineered for the Chevrolet Optra and New Optra vehicle platforms. The component is designed to facilitate reliable deceleration and thermal management within the vehicle's braking system. Its construction adheres to industry standards, ensuring direct fitment and operational compatibility with the original equipment manufacturer's specifications. This technical description provides necessary information for procurement and installation assessment.

Technical Specifications

• **Brand Designation:** HIQ
• **Manufacturer Part Number (MPN) / Stock Keeping Unit (SKU):** 3017
• **Component Classification:** Vented Front Axle Brake Disc Rotor
• **Manufacturing Origin:** China, produced under stringent quality control protocols.
• **Material Composition:** Utilizes high-carbon grey cast iron alloy, formulated for optimal thermal conductivity, high specific heat capacity, and resistance to thermal shock and fatigue.
• **Disc Diameter:** Precision-machined to OEM diameter specifications for correct caliper interface and brake pad sweep area.
• **Disc Thickness (Nominal):** Engineered for nominal thickness consistent with original equipment, ensuring proper caliper piston retraction and pad clearance.
• **Minimum Allowable Thickness:** Clearly marked on the disc’s edge for service life monitoring, a critical parameter for maintaining operational safety.
• **Hub Bore Diameter:** Designed to fit the vehicle's hub without eccentricity, crucial for maintaining rotational balance and preventing vibrations.
• **Bolt Pattern/PCD:** Configured precisely to the vehicle's wheel stud pattern, ensuring secure and concentric mounting to the wheel hub.
• **Surface Finish:** Non-directional swirl finish applied to the friction surface, promoting quicker brake pad bed-in and consistent initial braking performance.
• **Vane Configuration:** Internal cooling vanes optimize airflow, significantly contributing to efficient heat dissipation from the friction surfaces during braking events.

Compatibility & Fitment

• **Primary Vehicle Application:** Chevrolet Optra (Applicable to all international market variants and trim levels).
• **Secondary Vehicle Application:** Chevrolet New Optra (Applicable to all international market variants and trim levels).
• **Axle Integration:** Exclusively designed for the front axle position of the specified Chevrolet Optra and New Optra models.
• **Installation Modality:** Direct replacement component; no modifications to the existing brake caliper, caliper bracket, or hub assembly are required for installation.
• **System Interoperability:** Engineered to be fully compatible with both standard hydraulic braking systems and anti-lock braking systems (ABS) present in the applicable Optra and New Optra vehicles.
• **Reference OEM Part Numbers:** Cross-referenced against original equipment manufacturer specifications to confirm precise interchangeability and functional equivalence.

Key Performance Benefits

• **Thermal Performance Optimization:** The advanced vented design and high-carbon material effectively manage thermal energy generated during braking, significantly mitigating brake fade and maintaining consistent friction coefficients across varying operational temperatures.
• **Enhanced Braking Stability:** Precision manufacturing tolerances, including minimal run-out and parallelism, reduce variations in disc thickness, which prevents brake judder and pulsation, contributing to a stable and predictable braking event.
• **Extended Component Durability:** The robust material specification ensures superior wear resistance and structural integrity over the component's operational lifespan, thereby reducing the frequency of component replacement.
• **Optimized Noise, Vibration, and Harshness (NVH) Characteristics:** Strict adherence to dimensional accuracy and balanced mass distribution reduces the propensity for brake noise (e.g., squeal, groan) and unwanted vibrations transmitted through the steering wheel or pedal assembly.
• **Rapid Pad Bed-in:** The specialized non-directional surface finish applied to the disc friction area accelerates the conditioning process between the brake pads and the disc, leading to optimized braking performance shortly after installation.
