Our brake calipers for cars are pivotal components in the braking system. They house brake pads and pistons, using hydraulic pressure. When you press the brake pedal, the caliper pistons push the pads against the brake rotors, generating friction to slow or stop the vehicle.
These calipers are made from high - quality aluminum or steel, ensuring durability and heat resistance during braking. We offer both fixed and floating caliper types. Fixed calipers, with pistons on opposing sides, provide stable and powerful braking, ideal for high - performance driving. Floating calipers, featuring a single - piston design moving relative to the rotor, are more common and cost - effective, suitable for daily driving.
Our products are precision - engineered and rigorously tested to meet international safety and quality standards, guaranteeing reliable and efficient braking performance for your vehicle.
Using aerospace grade 6061-T6 aluminum alloy substrate (35% stronger than ordinary aluminum alloy), combined with CNC machining technology, the machining accuracy is controlled within ± 0.02mm, effectively reducing component wear during braking. According to third-party testing, after 1000 consecutive brake tests in extreme temperature environments ranging from -40 ℃ to 200 ℃, the piston sealing performance still maintains over 98%, and the service life can reach 80000 kilometers, far exceeding the industry average of 60000 kilometers. It perfectly adapts to the braking needs of various small cars and is a cost-effective choice for small car brake calipers.
The entire series of products have passed ISO 9001 quality system certification and TS16949 automotive industry special certification. Each small car brake caliper has undergone 12 rigorous tests (including hydraulic strength, airtightness, braking response speed, etc.). Data shows that the braking response time is only 0.3 seconds (industry average 0.5 seconds). In the 100-0km/h braking test, the braking distance can be shortened by 2-3 meters, providing dual protection for daily driving and emergency braking, allowing customers to confidently choose compliant and high-performance brake caliper products.
Developed based on data from over 2000 small car models worldwide, using a "one-to-one" OE version replica that can be directly installed without additional modifications (with a compatibility rate of 99.5%). Targeting popular models of mainstream brands, we have launched a customized small car brake caliper set, which includes specialized installation accessories and instructions. Even beginners can replace it within 30 minutes, solving the pain points of traditional brake caliper installation and improving customer experience.
Innovatively adopting a dual piston symmetrical layout design, compared to a single piston brake caliper, the brake pressure distribution is more uniform (pressure error ≤ 5%), which can reduce the problem of brake eccentric wear. Paired with high friction coefficient brake pads (friction coefficient 0.45), after 5 consecutive emergency braking cycles, the brake attenuation rate is only 8% (industry average 15%), which can maintain stable braking performance even in complex road conditions such as mountain roads and rainy days. It is a high-quality small car brake caliper solution for customers who pursue driving safety.
Providing a rare "lifetime warranty" commitment in the industry, customers who purchase this product can enjoy free replacement services if the malfunction is caused by product quality issues (non-human damage). Relying on over 30 global after-sales service outlets, the after-sales response time does not exceed 24 hours, solving cross-border customer after-sales problems. As of 2025, we have provided brake caliper products and services to over 100000 small car owners, with a customer satisfaction rate of 96%, winning market trust with our strength.

Here are specific application scenarios of brake caliper:
Targeting frequent starts and stops during morning/evening rush hours (over 300 brakes per day), the product has a brake response time of ≤0.3 seconds, 40% faster than the industry average, enabling quick response to emergencies. After a one-month urban road test, the brake pad wear is only 0.2mm, suitable for mainstream family commuter cars, ensuring daily travel safety.
For long hours of high-speed driving (single trip over 300km), the product uses EPDM seals resistant to 200℃ high temperatures, maintaining 98% sealing performance after 100 consecutive brakes. Third-party tests show that the emergency braking distance at 120km/h is 2.5 meters shorter than ordinary calipers, relieving braking anxiety during long drives.
Aiming at slippery road surfaces in rainy days (brake friction coefficient easily drops by 30%), the product body shows no rust after 96-hour salt spray test, and the piston surface is anodized to prevent rain erosion. In simulated heavy rain tests, the braking stability reaches 92%, suitable for all types of cars, ensuring reliable braking in humid environments.
For vehicles over 5 years old (seal aging rate of original calipers exceeds 60%), the product can directly replace OE parts (compatibility rate 99.5%), increasing braking efficiency by 35% after installation. Tests show that the 100-0km/h braking distance of old vehicles is shortened by 3 meters after replacement, solving the problem of weak braking.
Designed for owners pursuing handling, the dual-piston structure ensures brake pressure error ≤5%. Equipped with brake pads with a friction coefficient of 0.45, the continuous braking fade rate is only 8% after 10 tests on mountain bends. It meets DOT FMVSS 105 safety standards, satisfying the demand for improved braking performance in light modifications.
After unpacking, first check the brake caliper's appearance (no scratches/deformation). Use a pressure gauge to test the hydraulic channel's tightness (pressure ≥18MPa with no leakage). Refer to the OE manual to confirm all accessories are complete, avoiding installation errors.
Clean oil stains on the brake disc surface. Align the caliper with the bracket bolt holes (torque set per manual, usually 25-35N·m). After installation, manually push the piston (stroke 10-15mm is appropriate) to ensure no jamming.
Start the vehicle, shift to neutral, and press the brake pedal 3-5 times (to build hydraulic pressure). Test brake response during low-speed driving (braking distance should shorten evenly). Avoid hard braking within the first 100km to allow full component break-in.
Inspect the caliper's seals every 20,000km (no aging/oil leakage). Clean brake components after rainy days. If abnormal brake noise or increased pedal travel is found, conduct timely inspection (it is recommended to contact certified maintenance personnel).
