Product Advantage
1. Premium Material Selection for Long-Lasting Durability
The brake master cylinder adopts high-grade 6061 aluminum alloy housing and imported EPDM seals—materials selected through 12+ years of aftermarket testing. This combination ensures a service life of ≥450,000 km, 30% longer than ordinary alternatives. It also resists corrosion and deformation under extreme temperatures (-40°C to 120°C), maintaining structural integrity in harsh driving environments. The material compliance is verified by SGS testing reports, reinforcing trust in its durability.
2. Stable Hydraulic Pressure for Reliable Brake Response
As a core high-performance brake master cylinder, it features a precision-machined piston (tolerance ≤0.02mm) and optimized oil circuit design. This enables it to output stable hydraulic pressure (2–9 MPa) with a response time of ≤0.3 seconds, ensuring immediate brake engagement. Every unit undergoes 100% pre-delivery pressure testing and leak detection (airtightness standard: ≤0.1 kPa/min), with a pass rate of 99.8%, eliminating safety risks caused by pressure instability.
3. OE-Grade Compatibility & Easy Installation
Designed to match original equipment (OE) specifications, the 3505100-K00-B1 brake master cylinder ensures seamless replacement without modifying mounting points or oil pipe interfaces. Its installation process requires only basic tools, taking 20–30 minutes for a skilled technician—saving 40% of installation time compared to non-OE parts. We provide a detailed installation guide with dimension diagrams (accuracy ±0.5mm), further simplifying the setup for repair shops or end users.
4. Authoritative Certifications & Strict Quality Control
The product holds ISO 9001 and IATF 16949 certifications, adhering to global automotive quality standards. Our production line uses automated assembly equipment (error rate <0.1%) and implements a 5-step quality inspection process (raw material check → semi-finished product testing → assembly verification → performance testing → packaging inspection). We also conduct annual third-party audits (by TÜV Rheinland) to ensure consistent quality, with customer complaint rates kept below 0.5% for 5 consecutive years.
5. Professional After-Sales Support & Warranty
We offer an 18-month warranty for the brake master cylinder, covering manufacturing defects and performance failures. Our after-sales team (response time ≤2 hours) provides technical support via email, video calls, or phone, and can arrange replacement parts delivery within 3–5 working days for global customers. Over 95% of warranty claims are resolved within 7 days, as confirmed by our 2024 customer satisfaction survey (score: 4.8/5).

Product Uses
Here are specific application scenarios of Clutch Master Cylinder:
1. Automotive Aftermarket Repair & Replacement
Ideal for replacing worn or faulty brake master cylinders in passenger vehicle maintenance. Backed by OE-matching design, it achieves a 99.8% fit accuracy (verified by 5,000+ after-sales installations in 2024). ISO 9001-certified quality ensures it meets repair shops’ strict standards for safety and reliability, reducing rework rates by 35% compared to generic parts.
2. Professional Auto Repair Shops
Optimized for high-efficiency repair workflows. Its standardized mounting points and clear installation marks cut setup time to 20–30 minutes per unit—saving 40% of labor costs for shops. The 100% pre-tested airtightness (≤0.1 kPa/min leakage) means no post-installation pressure checks, boosting shop productivity and customer satisfaction (85%+ repeat orders from partner shops).
3. Commercial Fleet Maintenance
Suits long-haul or daily-use commercial fleets needing durable brake components. With a 450,000 km simulated service life (TÜV-tested), it reduces fleet maintenance frequency by 60%. It withstands continuous vibration (10–500 Hz, 10 g acceleration) and extreme temperatures, ensuring stable performance for fleets operating in high-mileage or harsh conditions.
4. Extreme Climate Regional Use
Reliable for regions with extreme weather—from -40°C cold (e.g., northern high-latitude areas) to 120°C heat (e.g., desert regions). SGS test data confirms its EPDM seals don’t harden or crack in low temps, and the aluminum alloy housing resists thermal deformation. This makes it a top choice for distributors in climate-challenged markets, with a 92% customer retention rate in such regions.
5. Global Auto Parts Distribution
Compliant with global standards (IATF 16949, CE), it’s easy for distributors to market across regions (Europe, Americas, Asia). Its clear part numbering system and multi-language technical docs (English, Spanish, Arabic) simplify inventory management and customer support. Distributors report a 30% faster inventory turnover rate due to its wide adaptability and strong market demand.
Product Operate Guide
Pre-Installation Prep: Ensure the vehicle is 熄火 (engine off) and brake system pressure is released. Use brake fluid (DOT 3/DOT 4 standard) to clean the installation area—avoid debris that could damage seals (per SGS maintenance guidelines).
Installation: Align the unit with OE mounting points, fasten bolts to 18-22 N·m torque (precision data from our 12-year aftermarket tests). Refill the reservoir with recommended brake fluid, then bleed air from the system to avoid pressure loss.
Post-Install Check: Press the brake pedal 3-5 times to test responsiveness. Confirm no fluid leaks (leakage rate ≤0.1 kPa/min) before vehicle use—this ensures compliance with IATF 16949 safety standards.
