Ford Changan Rear Brake Disc

Enhance the braking performance of your Ford vehicle with the precisely engineered GN152A315AA Ford Changan rear brake disc. As a high-performance replacement part manufactured to strict OEM standards, this brake disc delivers the braking efficiency and durability expected of a genuine Ford component.

Crafted from premium cast iron, the Ford Changan rear brake disc GN152A315AA
ensures excellent heat dissipation and resistance to deformation. Each brake disc undergoes stringent quality control to guarantee dimensional accuracy and balanced rotation. When the brake pedal is engaged, the caliper presses high-friction brake pads against the disc surface, efficiently converting kinetic energy into controlled braking force.

Designed for Durability:

• Precision-Balanced – Reduces vibration for smooth braking.
• Optimized Thermal Management – Resists brake fade during continuous use.
• Anti-Corrosion Treatment – Protective coating extends service life.
• Direct OE Replacement – No modifications required.

Reasons to Choose This Brake Disc:
✓ Perfect Fit – Tailored specifically for your Ford model.
✓ Enhanced Safety – Restores original braking performance.
✓ Long-Lasting – Robust construction built for daily driving.
✓ Easy Installation – Plug-and-play design for straightforward maintenance.
✓ Quality Assured – Manufactured to Ford's stringent standards.

Drive with confidence in your Ford's braking. The GN152A315AA rear brake disc delivers reliable, responsive braking performance across all driving conditions.

During the production process of GN152A315AA brake discs for Ford Changan vehicles
Cutting-edge Technology Layer: Precision Performance Regulation of Laser Engraving
To pursue ultimate performance and quietness, laser technology has been applied to the surface treatment of brake discs. Laser surface treatment is mainly divided into scoring, quenching, cladding and other methods.

Laser Surface Scoring: High-energy laser beams are used to precisely carve specific patterns (such as M-shaped grooves) on the friction surface. These micro-grooves can optimize the heat flow distribution during braking and facilitate debris discharge, thereby improving friction stability and suppressing the generation of specific frequency noise (NVH) at the source.

Laser Surface Quenching: The disc surface is locally heated at high speed and then rapidly cooled to achieve surface phase transformation hardening. This process not only increases local hardness but also crucially converts harmful residual tensile stress on the surface into beneficial residual compressive stress.

The optimization of this stress state can significantly enhance the fatigue resistance life and deformation resistance of brake discs, enabling them to maintain higher stability and reliability under long-term alternating thermal loads.

In terms of equipment configuration, we abandon the traditional single-machine independent operation mode and deploy a fully automated CNC precision machining production line, which is completely different from the equipment combination we mentioned before. The production line includes CNC precision turning centers, double-end surface grinding machines, high-precision drilling and tapping machines, and online ultrasonic flaw detection equipment, all of which are equipped with intelligent control systems. The equipment can automatically call the OE parameter template according to the brake disc model, adjust the spindle speed (3000-8000r/min) and feed rate (0.1-0.3mm/r) in real time, and realize seamless connection from blank clamping to semi-finished product machining. What's more, we are equipped with a tool wear real-time monitoring system-the system can automatically detect the wear degree of the cutting tool, and send an alarm when it reaches the limit, avoiding machining defects caused by tool wear. This not only improves production efficiency but also ensures machining precision..

1. After replacing the rear brake disc of the new Ford Changan GN152315aa model, is a "break-in period" required? What are the correct procedure steps?​
Recommended Procedure: Yes. Proper bedding-in helps transfer brake pad material evenly onto the brake disc surface, forming a stable friction layer. It is recommended to perform 8–10 moderate brakings (decelerating from approximately 80 km/h to 30 km/h) in a safe driving environment, avoiding harsh or prolonged braking. After bedding-in, braking performance will gradually improve to its optimal level.

2. Do dark patches or "blue spots" on the brake disc surface affect safety?​
Possible Cause: These patches are caused by localized overheating, which alters the metal's microstructure (oxidation discoloration). Slight patches generally do not affect braking performance. However, if accompanied by braking vibration or reduced efficiency, it may indicate uneven heat distribution on the brake disc. Long-term overheating can accelerate disc aging, so it is advisable to inspect braking system load and cooling conditions.

A key trend that cannot be ignored is the segmentation of technological iteration, which breaks the long-term "one-size-fits-all" technological pattern of the industry. In the past, brake disc technology upgrades mostly focused on material hardness and heat dissipation, but now, with the diversification of vehicle types (fuel vehicles, pure electric vehicles, hybrid vehicles, commercial vehicles) and usage scenarios (urban commuting, high-performance driving, harsh environment operations), technological iteration has become more refined. For example, for pure electric heavy-duty vehicles, manufacturers have developed brake discs withboron-doped bainitic alloy cast iron as the substrate, which can withstand the high load brought by the heavy body and frequent braking; for high-performance sports cars, the application of carbon-ceramic composite materials has become more widespread, which not only reduces unsprung weight but also improves thermal stability by 60% compared to traditional cast iron brake discs. In addition, the integration of intelligent detection technology into the production process-such as online eddy current flaw detection and 3D topography scanning-has become a standard configuration for formal manufacturers, ensuring that every brake disc meets the functional safety requirements of ISO 26262.
