ABS SL 4017 Brake Hose

ABS SL 4017 Brake Hose: A Comprehensive Overview

The ABS SL 4017 Brake Hose is a critical component in the braking system of many automotive models, particularly those manufactured by Mitsubishi and Proton. Designed to withstand high pressures and temperatures, this hose ensures reliable transmission of hydraulic fluid from the master cylinder to the brake calipers or wheel cylinders.

Key Features and Specifications

• Material Composition: Constructed from high‑grade, flexible rubber reinforced with a durable steel braid. This combination provides excellent resistance to abrasion, heat, and chemical degradation.
• Pressure Rating: Rated for a maximum operating pressure of up to 3000 psi (pounds per square inch), ensuring safe performance under extreme braking conditions.
• Temperature Range: Operates effectively between -40°C and +120°C, accommodating both cold climates and high‑temperature driving scenarios.
• Diameter: Standard internal diameter of 0.75 inches (19 mm) with an external diameter that fits seamlessly into existing brake lines.
• Length: Available in multiple lengths (typically 1.5 to 3 meters) to match various vehicle chassis configurations.
• Compatibility: Specifically engineered for Mitsubishi and Proton models such as the Colt, Lancer, Mirage, Persona, Satria, and Wira. The hose also fits other vehicles that use the same ABS brake system architecture.
• Installation Type: Equipped with standard fittings (M10x1.0 or equivalent) for quick and secure attachment to brake lines.

Design Advantages

The ABS SL 4017 Brake Hose incorporates several design elements that set it apart from generic brake hoses:

• Steel Braiding: The braided steel layer provides structural integrity, preventing kinking and maintaining consistent fluid flow even under heavy load.
• Multi‑Layer Construction: A multi‑layered rubber core offers flexibility while the outer protective layer guards against environmental factors such as UV exposure and road salt.
• Seamless Integration: The hose’s fittings are engineered to match OEM specifications, ensuring a leak‑free seal and reducing the risk of brake fluid contamination.
• Durability: The combination of high‑temperature rubber and reinforced steel results in a service life that exceeds many aftermarket alternatives.

Installation and Maintenance Guidelines

Proper installation and routine maintenance are essential for optimal brake performance. Follow these steps to ensure the ABS SL 4017 Brake Hose functions correctly:

1. Preparation: Disconnect the vehicle’s battery and relieve brake system pressure by pumping the pedal until it reaches a firm stop.
2. Removal of Old Hose: Carefully detach the existing brake hose from both ends, noting the orientation of any fittings or seals.
3. Inspection: Examine the new hose for any visible defects such as cracks, bulges, or manufacturing inconsistencies. Reject any compromised units.
4. Installation: Attach the new hose to the master cylinder and caliper or wheel cylinder, ensuring that all fittings are tightened to the manufacturer’s torque specifications.
5. Bleeding: Bleed the brake system to remove air pockets, following the vehicle’s service manual procedure. This step is crucial for maintaining braking sensitivity.
6. Testing: After bleeding, test the brake pedal for firmness and responsiveness. A soft or spongy pedal may indicate air in the system or a faulty seal.
7. Periodic Inspection: Inspect the hose annually for signs of wear, such as discoloration or softening. Replace immediately if any deterioration is observed.

Compatibility with Vehicle Models

The ABS SL 4017 Brake Hose is specifically tailored for a range of Mitsubishi and Proton vehicles. Below is an overview of common models that utilize this hose:

• Mitsubishi Colt, Lancer, Mirage, Persona, Satria, Wira
• Proton Persona, 400, Hatchback, 300 Wira, Sedan Satria 1.6L
• Other vehicles that share the same ABS brake system architecture and require a 0.75-inch diameter hose.

Why Choose the ABS SL 4017 Brake Hose?

When selecting a brake hose, reliability and safety are paramount. The ABS SL 4017 Brake Hose offers:

• OEM‑Grade Quality: Manufactured to meet or exceed original equipment specifications.
• Consistent Performance: Maintains hydraulic integrity under varying temperatures and pressures.
• Long‑Term Reliability: Proven durability reduces the likelihood of brake failure.
• Ease of Installation: Standard fittings and dimensions simplify the replacement process.

Conclusion

The ABS SL 4017 Brake Hose is an essential component for maintaining the safety and performance of Mitsubishi and Proton vehicles equipped with ABS systems. Its robust construction, precise engineering, and compatibility with a wide range of models make it the preferred choice for both professional mechanics and knowledgeable DIY enthusiasts. By adhering to proper installation and maintenance procedures, owners can ensure that this critical brake system element delivers reliable performance for years to come.
