Parts for your 2014 Nissan Serena-Brake hose

2014 Nissan Serena brake hose — purpose, care and when to replace

A brake hose is absolutely fitted to the 2014 Nissan Serena (C26). Nissan’s Factory/Electronic Service Manual for the C26 (Brake System — BR section, 2013–2016) specifies flexible hydraulic brake hoses at each wheel to accommodate suspension and steering movement. The Nissan FAST parts catalogue lists distinct front and rear brake hose part numbers for this model. Flexible hose construction and performance are governed by standards such as SAE J1401, which the Serena’s hoses conform to. So, a brake hose is relevant and used on the 2014 Serena.

The brake hose is the flexible link between the rigid brake lines on the body and the moving bits at the wheel end. When the driver presses the pedal, brake fluid pressure travels through these hoses to the callipers or wheel cylinders. Because the wheels steer and bounce over bumps, a rigid line can’t do this job — the hose allows safe movement without kinking or leaking.

• What can go wrong: surface cracking from age, swelling from fluid contamination, chafing from contact with suspension, internal collapse restricting flow, and fluid leaks at crimped ends or banjo fittings.
• What it feels like: spongy pedal, the car pulling to one side under braking, brakes dragging after release, visible wetness around hose joints, or an ABS warning if fluid loss affects system pressure.

For servicing in Australia and New Zealand, it’s smart to have the brake hoses inspected at every service or at least every 10,000–15,000 km. Look for cracking, bulges, abrasion marks, corrosion on fittings, and any dampness. Many workshops recommend preventive replacement around 8–10 years or 160,000–200,000 km, sooner if the vehicle tows, lives near the coast, or sees rough roads.

• Always replace hoses in axle pairs (both fronts or both rears) to keep braking even.
• Use line spanners on flare nuts, support the calliper to avoid straining the new hose, and replace copper sealing washers on banjo bolts.
• Route and clip the hose exactly as per the factory layout to prevent rubbing and twisting, keeping clear of the ABS wheel-speed sensor lead.
• After fitting, bleed the system with the fluid grade shown on the reservoir cap (commonly DOT 3 for the Serena in many markets, some use DOT 4). Avoid mixing grades.
