This brake caliper is a premium, direct replacement component engineered to the highest OEM standards for Chery vehicles. Crafted from high-grade GG20 cast iron and finished with an advanced electro-deposition coating, it provides exceptional corrosion resistance, ensuring longevity even in harsh driving conditions.
Precision-machined for a perfect fit, it guarantees seamless installation without modification. The caliper undergoes rigorous testing, including pressure cycles exceeding 10,000 times and a 500-hour salt spray test, to validate its structural integrity and performance. It ensures optimal clamping force on the brake pads, delivering reliable, responsive braking and consistent pedal feel. This results in enhanced driving safety, reduced stopping distances, and restored factory-level performance for your vehicle's braking system.
Our brake calipers undergo an advanced electro-deposition (E-coating) process, forming a uniform, protective layer that thoroughly seals all surfaces, including internal bores and complex passages. This is critical for resisting road salts, moisture, and harsh chemicals that cause rust and seizure. Independent lab tests confirm our coating withstands over 500 hours of salt spray (ASTM B117 standard) without failure, significantly outperforming standard paints. This extended defense ensures smooth piston movement and prevents premature wear, directly translating to longer service life and unwavering reliability, even in the most demanding climates.
We eliminate the hassle of installation with precision CNC-machined components that guarantee a perfect OEM match. Every mounting point, bleeder screw location, and piston bore is manufactured to exact original specifications, ensuring a seamless, bolt-on replacement. This commitment to dimensional accuracy, with tolerances within ±0.01 mm, means there is no need for modifications, forcing, or potential damage to other brake system parts. This perfect fit restores your vehicle's factory braking geometry, ensuring optimal performance and safety from the first drive, while saving valuable time and labor costs.
Beyond meeting OEM standards, every caliper in our lineup is subjected to a brutal validation cycle that simulates a lifetime of extreme use. Our products are proven through over 25,000 high-pressure cycle tests and 3,000 km of dynamometer testing, replicating severe conditions from high-speed deceleration to constant stop-and-go traffic. These tests validate the structural integrity of the housing and the resilience of internal seals. This data-driven approach guarantees that our calipers will not falter under pressure, providing you with a component built for durability and consistent, high-performance stopping power.
Engineered for stability under thermal stress, our calipers are constructed from high-grade GG20 grey iron, known for its excellent heat dissipation properties. We pair this with high-temperature piston seals and boots made from EPDM rubber, capable of withstanding continuous operation at over 250°F (120°C). This robust combination prevents fluid vaporization (brake fade) and maintains consistent pedal feel during repeated heavy braking. The superior sealing technology also effectively locks out contaminants, preserving the integrity of the brake fluid and the internal piston mechanism for long-term, trouble-free operation.
The foundation of a reliable brake caliper is its raw material. We exclusively use GG20+ grade grey iron, which offers a superior tensile strength of over 250 MPa and consistent casting density, providing a robust and crack-resistant foundation. This is coupled with chromo-plated pistons that resist pitting and corrosion, ensuring smooth operation. By sourcing and verifying our materials against strict international standards, we ensure every caliper has the inherent strength to handle the immense hydraulic pressures and mechanical stresses of daily braking, delivering peace of mind and absolute safety.

Here are specific application scenarios of brake caliper:
When your vehicle's braking performance declines, evidenced by pulling to one side during stops or a spongy brake pedal, it often points to a failing rear caliper. Internal corrosion or a stuck piston can cause uneven pad wear and reduce braking efficiency. Replacing it with our high-performance caliper restores balanced, factory-spec braking force. This is a critical maintenance procedure to ensure safety and prevent further damage to expensive components like brake discs, typically recommended every 60,000-75,000 miles or as inspection dictates.
Over time, rear brake calipers can succumb to environmental factors like road salt and moisture, leading to corrosion that compromises their function. This restoration scenario is crucial for recovering optimal safety margins. Our E-coated caliper directly addresses this by providing superior corrosion resistance, tested to withstand over 500 hours of salt spray. Installing it eliminates the risks of reduced braking power and uneven pad contact, ensuring your vehicle's braking system operates with the reliability and responsiveness required for safe daily driving.
Specific symptoms like an illuminated brake warning light, a leaking brake fluid, or the vehicle failing to release properly after braking are clear indicators of a caliper failure. These issues often stem from ruptured seals or a seized piston. Our product, validated through 25,000 high-pressure cycles, offers a definitive solution. Its precision engineering ensures perfect seal alignment and smooth piston operation, directly resolving fluid leaks, dragging brakes, and restoring the correct hydraulic pressure for immediate and safe operation.
For fleet managers operating a range of vehicles, maintaining uniform safety standards and minimizing downtime is paramount. This rear brake caliper, built to consistent OEM-quality specifications, is an ideal bulk replacement part. Its guaranteed direct fit allows for rapid, predictable installation, getting vehicles back on the road faster. The documented durability and extended service life, backed by rigorous testing data, translate into lower total cost of ownership, reduced repeat repairs, and enhanced operational safety for entire fleets.
For optimal performance and safety, always install this OEM-approved brake caliper as a complete axle pair. Prior to installation, thoroughly inspect the brake hose and rotor for wear. Use a torque wrench to tighten mounting bolts to the specified 80-100 Nm to ensure secure fitment. After installation, it is critical to bleed the brake system completely to remove all air pockets, following the vehicle's recommended procedure. Test brake function at low speeds in a safe area before normal driving. Regular visual inspections are recommended every 15,000 km to ensure integrity and performance.
