Design Features and Benefits

The A.B.S. SL 5791 incorporates several design elements that set it apart from standard aftermarket hoses:

• Dual‑Layer Construction: The inner PTFE liner resists corrosion and chemical degradation, while the outer rubber sheath provides mechanical strength and abrasion resistance.
• High‑Temperature Resistance: Maintains structural integrity even in extreme heat generated by braking systems.
• Flexibility and Durability: Engineered to flex with vehicle suspension movement without compromising seal integrity.
• Leak‑Proof Seal: Flanged fittings ensure a tight, leak‑free connection that meets OEM standards.

Installation Guidelines

Proper installation is critical for optimal performance. Follow these steps to install the A.B.S. SL 5791 brake hose:

1. Remove Existing Hose: Carefully detach the old brake hose from both ends, noting the orientation of any fittings.
2. Inspect Fittings: Check for wear or damage on flanges and gaskets; replace if necessary.
3. Attach New Hose: Slide the new hose onto the flanged fittings, ensuring correct alignment. Tighten bolts to manufacturer specifications (typically 20–25 Nm).
4. Check for Leaks: After reassembly, pressurize the brake system and inspect all connections for any signs of leakage.
5. Test Drive: Perform a short test drive to confirm that braking performance is consistent and there are no abnormal noises or vibrations.

Compatibility Summary

The A.B.S. SL 5791 brake hose is specifically engineered for the following vehicle models:

• Toyota Yaris (2001‑2005)
• Toyota Vitz (2001‑2005)
• Other compact Toyota models with similar rear brake hose specifications may also be compatible after verification.
