ABS SL 3191 Brake Hose

ABS SL 3191 Brake Hose

The ABS SL 3191 is a high‑performance flexible brake hose engineered for the demanding braking systems of Mercedes‑Benz vehicles. Designed with precision and durability in mind, this component delivers reliable hydraulic pressure transmission while maintaining flexibility under extreme operating conditions.

Key Specifications

• Model: SL 3191
• Material: Premium reinforced rubber with an inner steel braid for strength and heat resistance.
• Weight: 0.1 kg per hose, ensuring minimal added mass to the braking system.
• Thread Size (Rosca 2): Inner diameter M10x1 mm, compatible with standard brake line fittings on Mercedes‑Benz chassis.
• Length: Available in multiple lengths (commonly 370 mm) to fit front axle configurations.
• Color: Classic black for seamless integration into vehicle interiors.

Vehicle Compatibility

The ABS SL 3191 is specifically engineered for a wide range of Mercedes‑Benz models, ensuring optimal fitment and performance. Commonly supported vehicles include:

• Mercedes‑Benz 190 (W201)
• Mercedes‑Benz S‑Class (W126)
• Mercedes‑Benz E‑Class (W124)
• Mercedes‑Benz SL (R107, R129)
• Mercedes‑Benz C‑Class (C124 Coupe)
• Mercedes‑Benz 123 Series (T‑Model)

Design and Construction

The hose features a multi‑layer construction that balances flexibility with structural integrity:

1. Inner Core: High‑grade elastomer capable of withstanding hydraulic fluid pressure up to 300 bar.
2. Steel Braiding: A tightly wound steel wire braid provides tensile strength, preventing kinking and maintaining shape under load.
3. Outer Sheath: Durable rubber coating resists abrasion, UV exposure, and chemical degradation from brake fluid.

Performance Highlights

• Heat Resistance: Maintains elasticity at temperatures up to 200 °C, preventing hose contraction during heavy braking.
• Pressure Stability: Consistent hydraulic pressure transmission ensures responsive brake pedal feel and reliable stopping power.
• Low Weight: At only 0.1 kg per unit, the hose contributes negligible mass to the vehicle’s front axle dynamics.
• Long Service Life: Designed for extended durability, reducing maintenance frequency compared to standard hoses.

Installation Guide

Installing the ABS SL 3191 is straightforward and can be completed with basic automotive tools. Follow these steps for optimal results:

1. Disconnect the vehicle’s battery to ensure safety during brake system work.
2. Remove the old brake hose by loosening the M10x1 fittings on both ends using a suitable wrench.
3. Inspect the brake lines and calipers for any signs of wear or damage; replace if necessary.
4. Attach the new ABS SL 3191 to the fitting, ensuring the inner thread (M10x1) is fully seated.
5. Tighten the fittings securely but avoid over‑torqueing to prevent damage to the hose threads.
6. Bleed the brake system according to manufacturer specifications to eliminate air pockets.
7. Reinstall the battery and perform a test drive to confirm proper brake function.

Maintenance Tips

• Regularly inspect hoses for signs of cracking, bulging, or leaks.
• Avoid exposing hoses to extreme temperatures or direct sunlight for prolonged periods.
• Replace hoses after a recommended service interval (typically every 60,000 km) or if any damage is observed.

Why Choose ABS SL 3191?

The ABS SL 3191 combines proven engineering with meticulous material selection to deliver a brake hose that meets the rigorous standards of Mercedes‑Benz vehicles. Its lightweight construction, robust heat resistance, and precise thread compatibility make it an ideal choice for both OEM replacements and high‑performance aftermarket applications.

Conclusion

When selecting a brake hose for your Mercedes‑Benz, the ABS SL 3191 stands out as a reliable, durable, and performance‑oriented option. Its thoughtful design ensures that every braking event is met with confidence, safety, and consistent response.
