ABS SL 5718 Brake Hose

ABS SL 5718 Brake Hose

The ABS SL 5718 is a high‑performance brake hose designed for modern automotive braking systems. It combines advanced materials with precise engineering to deliver reliable, consistent performance under demanding conditions.

Key Features and Specifications

• Material Composition: Constructed from reinforced high‑temperature silicone rubber bonded to a durable polyurethane inner lining, the hose resists heat, abrasion, and chemical exposure.
• Pressure Rating: Rated for up to 250 bar (3600 psi), ensuring safe operation even in high‑performance or heavy‑load vehicles.
• Temperature Range: Operates effectively between -40°C and +120°C, accommodating extreme climates and engine heat.
• Length Options: Available in multiple lengths (e.g., 0.5 m, 1.0 m, 1.5 m) to fit a variety of vehicle architectures.
• Threading: Standard M10x1.0 threads for quick and secure connections on most brake lines.
• Color Coding: Typically marked with a red stripe to indicate hydraulic fluid compatibility, aiding in correct installation.

Compatibility Overview

The ABS SL 5718 is engineered for use across a broad spectrum of vehicles. Its universal design allows it to fit:

• Front and rear brake systems on Volkswagen, Audi, Porsche, and other VAG group cars.
• Heavy‑duty trucks and commercial vehicles that require robust hydraulic lines.
• High‑performance sports cars where precise braking response is critical.

Because the hose uses standard M10x1.0 threading, it can be swapped into most OEM brake line assemblies without modification.

Installation Guidelines

1. Preparation: Ensure the vehicle’s brakes are depressurized before handling any components. Wear protective gloves and safety glasses.
2. Removal of Old Hose: Carefully unscrew the old hose from both ends, noting the orientation of the threads to maintain proper alignment.
3. Inspection: Check the new ABS SL 5718 for any visible defects such as cracks or bulges. Verify that the inner lining is intact and free of debris.
4. Connection: Thread the hose onto the brake line fittings, tightening to manufacturer specifications (typically 2–3 turns beyond hand‑tight). Use a torque wrench if available.
5. Sealing: Apply a small amount of compatible hydraulic sealant on the threads to prevent leaks.
6. Bleeding: Bleed the brake system according to vehicle service manual, ensuring that air is removed and fluid flows smoothly through the new hose.

Maintenance Tips

• Regular Inspection: Check for signs of wear such as swelling, discoloration, or soft spots. Inspect at least once a year or after any major braking event.
• Avoid Physical Damage: Keep the hose clear of sharp objects and avoid excessive bending that could compromise its integrity.
• Fluid Compatibility: Use only brake fluids specified by the vehicle manufacturer (DOT 4, DOT 5.1, or equivalent). Mixing incompatible fluids can degrade the hose material.
• Temperature Management: In high‑heat environments, consider installing a heat shield to protect the hose from prolonged exposure to engine heat.

Safety Considerations

The ABS SL 5718 is designed to meet stringent safety standards. However, improper installation or use of incompatible fluids can lead to:

• Brake fluid leakage, reducing braking effectiveness.
• Hose rupture under high pressure, potentially causing catastrophic brake failure.
• Degradation of the silicone lining due to chemical exposure, leading to loss of hydraulic integrity.

Always follow the manufacturer’s guidelines and consult a qualified technician if unsure about any aspect of installation or maintenance.

Technical Advantages Over Conventional Hoses

• Enhanced Heat Resistance: The silicone outer layer withstands higher temperatures without softening, maintaining consistent pressure transmission.
• Improved Flexibility: The polyurethane core allows the hose to flex more readily, reducing stress on fittings and extending lifespan.
• Corrosion Protection: The dual‑layer construction resists corrosion from brake fluid additives and environmental exposure.
• Consistent Flow Dynamics: Precise manufacturing tolerances ensure minimal pressure drop across the hose, preserving braking performance.

Applications in Popular Vehicle Models

The ABS SL 5718 is frequently used in:

• Porsche Cayenne – front and rear brake lines for enhanced stopping power.
• Audi Q7 – flexible hose solutions that accommodate the vehicle’s suspension geometry.
• Volkswagen Touareg – robust hydraulic lines capable of handling heavy‑load conditions.
• Various commercial trucks and SUVs requiring durable, high‑pressure brake hoses.

Conclusion

The ABS SL 5718 Brake Hose represents a blend of advanced materials, precise engineering, and universal compatibility. Its superior heat resistance, pressure tolerance, and flexible construction make it an ideal choice for both everyday driving and high‑performance applications. By adhering to proper installation and maintenance practices, users can rely on this hose to deliver safe, consistent braking performance throughout its service life.
