Check fitment for your specific vehicle (model, year, engine) before ordering. Also verify the production remarks and chassis cut-offs below against the vehicle identification number.

What This Product Does

The formed pipe conveys hydraulic fluid within the fixed braking pipework. The supplied exploded diagrams place it in assemblies covering the underbody, rear axle and vacuum lines; the assembly title does not mean this component is a vacuum pipe.

Functions

• Transfers brake fluid along a fixed hydraulic route.
• Links the relevant sections of braking pipework.
• Replaces the specified original left-hand line.

Symptoms of Fault

• Corroded surfaces, dents or other physical distortion.
• Fluid escaping from the pipework or connection points.
• A declining fluid level in the brake reservoir.
• Pedal softness, inconsistent feel, reduced braking response or a braking-system warning.

Why Replacement Matters

Leakage, corrosion or damage can compromise a pressurised hydraulic circuit. Renew a defective line with the correct application-specific component rather than selecting by appearance alone. These symptoms do not identify the pipe as the sole cause: hoses, connection fittings and calipers also require inspection. A suitably qualified technician should perform installation, bleed the circuit and check for leaks afterwards.

FAQs

Is this a braided replacement hose?
No. The supplied information identifies a rigid, formed brake pipe, not a flexible hose upgrade.

Why must the chassis cut-offs be checked?
Production changes introduced different pipe references. Selecting solely by model and year may overlook the applicable chassis sequence.

What information should be compared before ordering?
Match the vehicle's VIN, build date and existing part reference with the application list and diagram remarks. The listed quantity describes its use within the assembly, not a complete brake-line kit.
