Key Features & Technical Specifications

• Material Composition: Constructed from a premium blend of reinforced rubber and high‑grade synthetic fibers, the hose offers superior tensile strength and abrasion resistance.
• Inner Lining: The inner layer is coated with a specialized polymer that resists brake fluid degradation, ensuring consistent performance over extended periods.
• Pressure Rating: Rated for up to 200 bar, the PHA543 can handle the high pressures generated during aggressive braking without compromising integrity.
• Temperature Range: Operates effectively between -40°C and +120°C, accommodating extreme climates and high‑temperature brake systems.
• Flexibility & Durability: Designed to flex up to 90 degrees without kinking, the hose maintains a smooth internal surface that reduces friction and wear.
• Compatibility: Suitable for a wide range of vehicles including Renault Clio 3, Mégane 2, Scénic 2, as well as other models requiring the PHA543 reference.
• Dimensions: Standard length options include 210 mm with a diameter of M10x1, matching common fitting specifications for aftermarket and OEM installations.

Installation & Maintenance Guidelines

Proper installation is critical to ensure optimal braking performance. Follow these steps:

1. Preparation: Clean all mating surfaces with a solvent compatible with brake fluid to remove grease, oil, and contaminants.
2. Seating the Hose: Slide the hose onto the fitting carefully, ensuring that it sits flush without twists or kinks. The inner lining should remain smooth.
3. Tightening: Use a torque wrench to secure fittings to the manufacturer’s specified torque values, typically between 12–18 Nm.
4. Bleeding the System: After installation, bleed the brake system according to vehicle specifications to eliminate air pockets.
5. Inspection: Periodically inspect for signs of wear, bulging, or leaks. Replace any hose showing damage immediately.

Performance Benefits

• Consistent Hydraulic Flow: The smooth inner surface minimizes pressure drop, ensuring that brake fluid reaches the calipers with maximum force.
• Extended Service Life: High‑grade materials and robust construction reduce the likelihood of failure, extending maintenance intervals.
• Heat Resistance: Maintains structural integrity even under prolonged high temperatures, preventing hose expansion or rupture.
• Vibration Dampening: The reinforced design absorbs road‑induced vibrations, reducing noise and wear on connected components.

Applications & Vehicle Compatibility

The PHA543 is engineered to fit a variety of vehicle models. Common applications include:

• Renault Clio 3 – front and rear brake lines.
• Mégane 2 – both front and rear systems.
• Scénic 2 – versatile fit for multiple mounting points.
• Other models requiring the PHA543 reference, such as certain Kangoo, Modus, and Grand Scenic variants.
