2009 Subaru Impreza Brake Hose — What It Does and When To Replace It

Yes, the 2009 Subaru Impreza uses brake hoses. The Subaru Factory Service Manual for the 2008–2011 Impreza (GE/GH/GR) identifies flexible brake hoses at each wheel, and the Subaru parts catalogue lists front and rear flexible hose assemblies for this model range. These technical references confirm the brake hose is absolutely relevant and fitted on the 2009 Subaru Impreza.

The brake hose is the flexible section of the hydraulic brake line that connects the solid hard line on the chassis to the moving bits at each wheel (front calipers and, depending on trim, rear calipers or wheel cylinders). It has to handle steering and suspension movement without kinking while reliably carrying high-pressure brake fluid every time the pedal’s pressed. When a hose ages, the inner liner can swell or crack, leading to a soft pedal, pulling to one side, or longer stopping distances — none of which anyone wants.

As part of regular servicing on a 2009 Impreza, it’s smart to visually inspect all brake hoses at least every 12 months or 10,000–15,000 km. There’s no fixed replacement interval, but many technicians suggest replacing original hoses around the 10-year/150,000 km mark, or sooner if there’s any sign of wear. Look for surface cracking, wetness from fluid seepage, bulging under pedal pressure, twisted routing, chafing on struts or tyres, or rusty fittings.

When replacing, do both fronts or both rears together to keep braking feel even. Use quality, ADR-compliant or equivalent hoses, new copper sealing washers on banjo fittings, and the correct flare nut wrenches to avoid rounding fittings. After installation, bleed the system with fresh, correct-spec brake fluid (check the owner’s manual, Subaru commonly specifies DOT 3, with DOT 4 acceptable in many climates), and follow the factory bleeding order. With the car safely on stands, turn full lock both ways and compress the suspension to ensure hoses don’t rub or go taut. Secure them with the proper clips and make sure the orientation marks are right so the hose isn’t twisted.

If the Impreza is used for spirited driving or towing, consider more frequent inspections. Braided stainless hoses can sharpen pedal feel, but they must meet local standards and be installed correctly. Regardless of hose type, keeping the brake fluid fresh and the hoses healthy is key to consistent, confidence-inspiring stops.

• Tell-tale signs: soft or spongy pedal, car pulling under brakes, visible cracks, leaks, or bulges.
• Good practice: replace in axle pairs, use new sealing washers, and recheck for leaks after a short road test.

Popular questions about 2009 Subaru Impreza brake hoses

How often should the brake hoses be replaced on a 2009 Impreza?
There’s no strict interval, but many mechanics recommend inspecting at every service and planning replacement around 10 years or 150,000 km, earlier if there’s cracking, leaks, bulging, or a soft pedal. Age, heat, and road grime in Aussie and NZ conditions can accelerate wear.

What are the symptoms of a failing brake hose?
Common signs include a spongy pedal, the car pulling to one side when braking, visible wetness at hose ends, surface cracking, or a hose that swells when someone presses the pedal. In some cases a collapsed inner liner causes a brake to drag after you release the pedal.

Can braided stainless steel hoses be fitted, and are they legal in Australia and New Zealand?
Yes, provided they meet applicable standards and are installed correctly. Choose locally compliant, quality hoses and have them fitted by a competent professional. Some modifications may require certification, check local regulations before you upgrade.
