Product Uses
Here are specific application scenarios of Clutch Master Cylinder:
1. Daily Passenger Vehicle Commuting & Family Use
Ideal for vehicles used in daily urban commuting or family trips. Its 50,000+ km service life aligns with the average annual mileage (15,000–20,000 km) of most passenger vehicles, reducing replacement frequency. Compliant with ISO 9001, it maintains consistent braking response in stop-and-go traffic, ensuring safety for daily travels.
2. Light Commercial Vehicle Freight & Urban Distribution
Suitable for light trucks or vans in urban freight and distribution. It withstands 10MPa maximum working pressure—25% higher than industry averages—handling the frequent braking demands of delivery routes. The leak-proof seal (≤0.01 cc/min leakage rate) prevents hydraulic fluid loss, avoiding sudden braking failures during cargo transport.
3. Professional Aftermarket Repair & Maintenance
A top choice for auto repair shops and maintenance centers. Its CNC-machined bore (±0.005mm tolerance) ensures 100% OE-matching fit, cutting installation time by 30% compared to non-precision alternatives. Backed by 99.8% factory qualification rate, it minimizes rework risks for repair teams, improving service efficiency.
4. Extreme Climate Region Operation
Reliable for vehicles in regions with extreme temperatures. Its -40℃ to 120℃ operating range adapts to cold winters (e.g., Northern Europe) and hot summers (e.g., the Middle East). The NBR seal resists temperature-induced hardening or corrosion, maintaining performance even in harsh weather, verified by 500+ hours of climate chamber testing.
5. Global Auto Parts Distributor Inventory & Supply
Perfect for distributors building stable aftermarket inventory. With an annual production capacity of 50,000+ sets, we ensure 7–10 day lead times for bulk orders. The 12-month warranty also helps distributors reduce after-sales risks, as shown by our 98% customer retention rate for this product in European and Southeast Asian markets.
Product Operate Guide
For safety and performance, professional installation by certified technicians is recommended (per IATF 16949 automotive safety standards). First, inspect the cylinder for damage; ensure the NBR seal is intact. Clean the mounting surface to remove debris, then fasten with a torque wrench (18-22 N·m, matching industry torque specs). Bleed the brake system until no air bubbles appear—this maintains 10MPa working pressure. After installation, test braking 3-5 times at low speed to confirm smooth response. Avoid over-tightening, as it may damage the aluminum alloy body.
