Parts for your 2006 Subaru Impreza-Brake shoes

2006 Subaru Impreza brake shoes — what they do and when to replace them

Brake shoes are absolutely relevant on the 2006 Subaru Impreza. The Subaru Factory Service Manual (MY2006 Impreza/WRX), the Subaru FAST electronic parts catalogue, and Australian/NZ aftermarket catalogues (e.g., Bendix, Protex) all list rear brake shoes for this model range. Non-turbo trims commonly use rear drum brakes (primary brake shoes), while WRX/STI and some higher trims run rear disc brakes with a drum-in-hat handbrake that uses dedicated parking-brake shoes inside the rear rotors. Either way, the Impreza carries brake shoes on the rear axle—either for stopping or for the handbrake.

On a 2006 Subaru Impreza, brake shoes play one of two jobs. On models with rear drums, they’re the main friction parts that press outwards against the inside of the drum to slow the car. On models with rear discs, there’s a small set of shoes hidden inside the rotor “hat” that handles handbrake duties. It’s a simple, durable setup that keeps the handbrake strong and consistent, even if the rear service brakes are disc type.

For servicing, it’s smart to have the rear brakes inspected at regular service intervals—typically every 15,000–20,000 kilometres or at each scheduled service. A technician will check shoe lining thickness (replace when close to the manufacturer’s minimum, commonly around 1.5–2.0 mm of friction material), look for glazing or cracking, and make sure the drum or rotor hat surface is clean and within spec. They’ll also check and adjust the star wheel so the shoes sit close enough for a firm pedal and a short, positive handbrake lever travel without drag.

When replacing, always do both sides together (as an axle set) and consider a hardware kit—return springs, hold-down pins, adjusters, and the lever clip—so everything returns and adjusts properly. Lightly lubricate the six shoe contact points on the backing plate and the adjuster threads with high-temp brake grease, but keep grease off the linings and drum surfaces. After fitting, bed the shoes in with a few controlled stops or gentle handbrake applications at low speed to seat the linings nicely. For handbrake shoes on disc models, don’t over-tighten the cable to “create” bite—set the shoes first at the star wheel, then fine-tune the cable if needed.

Drivers who tow, tackle hills, or commute in stop–start traffic may see faster wear. Squeals, scraping, a spongy pedal, long handbrake lever travel, or poor holding on a slope are all cues it’s time for a check.

• Tell-tale signs: squeal/scrape noises, reduced rear braking, handbrake won’t hold on a hill, lever pulls too high.
• Good practice: replace as a pair, resurface or replace drums/rotors if scored, and bed-in after service.

Popular questions about 2006 Subaru Impreza brake shoes

Do all 2006 Imprezas have brake shoes?
Yes. Base/non-turbo models often run rear drum brakes with primary brake shoes. WRX/STI and some higher trims use rear disc brakes, but still have small drum-in-hat handbrake shoes inside the rear rotors. So every 2006 Impreza uses brake shoes in some form on the rear.

How often should the brake shoes be replaced?
It varies with driving, but inspection every 15,000–20,000 km is a safe bet. Rear drum shoes might last 60,000–120,000 km or more, while handbrake shoes on disc models often last even longer if correctly adjusted. Replace when near minimum thickness, if contaminated or cracked, or if the drum/hat surface is damaged.

Can just one side be replaced?
No—shoes should always be replaced in axle pairs for balanced braking. It’s also wise to refresh springs and hardware together and adjust the shoes evenly so pedal feel and handbrake holding power are consistent left to right.
