2017 Subaru Forester Brake Hose – Purpose, Care and When to Replace

Yes, the 2017 Subaru Forester uses flexible brake hoses. Technical references including the Subaru Service Manual for 2017MY Forester (Brake: Hydraulic Circuit/Brake Hose), Subaru parts catalogues for the SJ-series (listings for front and rear brake hoses), and the hose performance standard SAE J1401 (which covers OEM hydraulic brake hoses) all confirm this model is fitted with rubber-reinforced flex lines at each wheel to connect the rigid hard lines to the calipers.

On the Forester, each brake hose allows the suspension and steering to move freely while maintaining a sealed, high-pressure path for brake fluid. When the driver presses the pedal, fluid pressure travels through the master cylinder, hard lines and these flexible hoses to clamp the calipers. Because they live near heat, road grime and debris, hoses age over time: the rubber can harden, micro-crack or swell internally, which can lead to a soft pedal, pulling to one side, dragging brakes or, in worst cases, a fluid leak.

There’s no fixed kilometre-based replacement interval from Subaru for hoses, instead, they’re an inspect-and-replace item. A good rule in Australia and New Zealand is to have them checked at every service and especially from about the 6–10 year mark, sooner if the vehicle tows, sees gravel roads, coastal salt, or high heat. Any cracking, bulging, wetness, rusted fittings or kinked routing is cause for replacement. Always use the brake fluid grade specified in the owner’s manual (commonly DOT 3, DOT 4 compatible). Never use silicone DOT 5.

• Common symptoms of a tired hose: spongy pedal feel, uneven pad wear, the vehicle pulling under brakes, one wheel running hot, visible perishing/cracks, or dampness at crimp joints.
• Best practice when replacing: do both sides of the same axle, fit new sealing washers on banjo bolts, route and clip exactly as factory (no twists), use a flare-nut spanner on hard-line fittings, and bleed the system thoroughly. After bleeding, check pedal firmness and inspect for leaks with the wheels at full lock and full suspension travel.

Keeping the Forester’s brake hoses in top nick is a simple way to preserve confident pedal feel and straight, predictable stops. Pair hose inspections with regular fluid changes and pad/rotor checks and the braking system will stay safe and consistent.

FAQs

How often should brake hoses be replaced on a 2017 Subaru Forester?
They’re condition-based rather than mileage-based. In local conditions, have them inspected at every service and consider proactive replacement around 6–10 years, or earlier if there’s cracking, swelling, leaks or corroded fittings. Coastal, off-road or towing use can accelerate ageing.

What are the signs of a failing brake hose on a Forester?
Look for dampness at the hose ends, surface cracks, bulges, or rusted crimps. From the driver’s seat, watch for a soft pedal, pulling to one side, brakes not releasing cleanly after a stop, or a wheel running hot.

Is it safe to drive with a seeping or cracked brake hose?
No. A compromised hose can fail suddenly, causing a major loss of braking. Park the vehicle and arrange repair or towing. Replace in axle pairs and bleed the system properly before returning to the road.
