We offer full customization for brake and clutch hydraulic components, from complete systems to material-level adjustments—empowering clients with differentiated products for global markets.

We offer full customization for the entire brake and clutch hydraulic system as well as core components and materials. Our customizable products include:

Brake Master Cylinder

Brake Wheel Cylinder

Clutch Master Cylinder

Clutch Slave Cylinder

Load Sensing Proportioning Valve

Related Accessories: push rods, caps, seals, reservoirs, etc.

We support customizations across the following technical dimensions to ensure precise fit and optimal performance:

Pump Body Design: Adjustable body layout and interface geometry to suit specific vehicle architectures.

Material Selection: Material options include aluminum alloy, cast iron, and engineering plastic.

Sensor Configuration: Position and type of sensors (fluid level, ABS) can be customized.

Reservoir & Cap Design: Custom reservoir design with options for transparency, volume, and locking types.

Mounting Dimensions: Thread size, bolt holes, and external dimensions tailored to your platform.

Customization Methods & Timeline

We offer two customization models to suit different project needs. We specialize in both sample-based and drawing-based hydraulic cylinder customization. With flexible mold development, fast prototyping, and rigorous testing, we help clients reduce time-to-market and ensure fit-for-purpose performance for their target applications.

Full In-House Manufacturing Workflow

Our entire production process is fully in-house—from casting to packaging—ensuring complete control and traceability. Below is our standard 12-step workflow, each step optimized for quality and SEO search relevance.

Aluminum Melting & Gravity Casting

In-house casting with ZL11 alloy and T6 treatment ensures superior mechanical strength and corrosion resistance.

Rough Turning

Establishing rough dimensions for efficient CNC precision machining.

4-Axis CNC Machining

Precision machining for complex ports and contours with tight tolerances.

Precision Boring & Finishing

Ensures concentricity and surface finish for optimal piston movement.

Deep Hole Drilling

Deep-hole drilling for structural complexity such as long reservoirs or dual-piston types.

Manual Tapping or Special Machining

Manual handling of custom angles, threads, or interfaces.

Initial Inspection & Dimensional Verification

Critical dimensions and thread compatibility verified post-machining.

Porosity Inspection

Non-destructive inspection to detect casting porosity.

Sealing Performance Testing

Hydraulic pressure tests simulate brake/clutch actuation.

Vacuum Leakage Testing

Validates compatibility with vacuum boosters and seal integrity.

Endurance & Fatigue Testing

Cycle-tested for over 400,000 actuations to ensure durability.

Assembly & Final Packaging

Assembly under SOP, batch sampling, barcode traceability, and export packaging.

Whether you have a blueprint or just an idea, our engineering and production teams can turn it into a reliable solution.

Customization Advantages

Multiple customization methods: Sample-based or drawing-based development

Wide customization scope: Including reservoir, cap, housing, sensor, and materials (plastic, aluminum, iron)

One-on-one engineering support: From structure design to final testing

Top-tier component sourcing: All sealing cups are sourced from Datwyler, a world-class supplier of brake system rubber seals

Certification-ready delivery: All custom orders can include an official product identification and inspection report upon request

Our Testing Advantage:

Immediate detection of machining errors or surface flaws to prevent downstream quality issues.

Comprehensive seal verification under air, vacuum, and hydraulic conditions to eliminate risks like leakage, backflow, or booster malfunction.

Simulate over 100,000 cycles of operation to uncover fatigue, cracking, or wear issues before they reach the customer.

Combining expert manual inspection with automated precision equipment for accurate, repeatable testing.

We have built one of the most advanced integrated testing systems in the industry, embedding dimensional, sealing, and durability inspections throughout every production stage with full traceability.
