ABS SL 3877 Brake Hose

ABS SL 3877 Brake Hose

The ABS SL 3877 Brake Hose is a high‑performance hydraulic line designed for rear brake systems in a wide range of Citroën and Peugeot models, including the AX, Saxo, 106 II, and various van variants. Manufactured by A.B.S., this hose delivers reliable pressure transmission, durability, and resistance to heat and corrosion.

Key Features

• Material Composition: Reinforced with high‑grade steel wire braiding and a flexible inner liner that resists abrasion and chemical attack.
• Diameter & Length: Standard 222 mm internal diameter, available in lengths tailored to specific vehicle chassis configurations.
• Temperature Range: Operates effectively from –40 °C to +120 °C, ensuring consistent braking performance under extreme conditions.
• Pressure Rating: Rated for up to 300 bar (4,350 psi), meeting the stringent demands of modern hydraulic brake systems.
• Seal Integrity: Equipped with a double‑layer O‑ring seal that prevents fluid leakage and maintains system pressure over long service intervals.

Compatibility Overview

The ABS SL 3877 is engineered to fit the rear brake lines of the following vehicles (model years indicated for reference):

• CITROËN AX – 1994‑2004
• CITROËN SAXO – 1994‑2004
• PEUGEOT 106 I & II – 1994‑2004
• PEUGEOT VAN (Van II) – 1994‑2004
• Other Citroën/Peugeot models with a 222 mm rear brake line specification.

For each model, the hose is available in left and right rear configurations, ensuring proper fitment on both sides of the vehicle. The inner diameter matches the standard hydraulic fittings (M10x1.0) used across these platforms.

Installation Guidelines

1. Preparation: Clean all mating surfaces with a solvent to remove oil, grease, and debris. Inspect the hose for any visible damage before installation.
2. Fitting Placement: Slide the hose onto the rear brake caliper or wheel cylinder, ensuring that the O‑ring faces the fluid inlet.
3. Tightening Sequence: Use a torque wrench to tighten fittings in a cross‑pattern sequence. Follow manufacturer torque specifications (typically 15–20 Nm for M10x1.0 threads).
4. Leak Check: After tightening, pressurize the brake system and inspect all connections for leaks. Re-tighten if necessary.
5. System Bleed: Perform a full bleed of the rear brakes to remove air pockets, ensuring optimal hydraulic response.

Performance Characteristics

The ABS SL 3877 brake hose offers:

• Low Compressibility: Minimizes pressure drop across the line, providing a crisp and responsive braking feel.
• High Flexibility: Allows for smooth movement of suspension components without compromising hydraulic integrity.
• Corrosion Resistance: The steel braid is coated with a protective layer that resists rust even in high‑humidity environments.
• Heat Dissipation: The braided construction facilitates efficient heat transfer, reducing the risk of brake fade during prolonged use.

Maintenance & Longevity

Regular inspection is recommended every 20,000 km or annually, whichever comes first. Look for signs such as:

• Visible cracks or bulges in the hose wall.
• Degradation of the O‑ring seal (softening or hardening).
• Excessive wear on the steel braid.

If any of these issues are detected, replace the hose immediately to maintain braking safety. The ABS SL 3877 is designed for a service life exceeding 100,000 km under normal driving conditions when properly maintained.

Technical Specifications Summary
