2010 Subaru Impreza Brake Shoes — What They Do and When to Replace Them

Technical references including the Subaru GE/GH workshop manual (2008–2011) and OEM parts catalogues show that 2010 Subaru Impreza variants may be fitted with either rear drum brakes (which use service brake shoes) or rear disc brakes that incorporate an internal “drum-in-hat” handbrake using small parking brake shoes. That means brake shoes are relevant to the 2010 Impreza in all common configurations: as the primary rear brakes on drum-equipped models, or as dedicated handbrake shoes on disc-equipped models.

For the 2010 Impreza, brake shoes are the curved, friction-lined pieces that press outward against a drum. On cars with rear drums, they handle day-to-day stopping at the back. On models with rear discs, they live inside the rear rotor hat and are used solely for the handbrake, holding the car securely when parked. Either way, they’re small, unsung workhorses that need periodic inspection and the odd refresh to keep the Impreza safe and compliant.

During routine servicing, a technician should check shoe lining thickness, glazing, cracking and contamination from brake fluid or grease. As a rule of thumb, shoes approaching about 1.5 mm of remaining friction material are due for replacement. The hardware kit (springs, hold-down pins and adjusters) deserves attention too, tired springs or a sticky adjuster can cause poor handbrake hold, uneven wear or dragging. On drum rear brakes, wheel cylinders should be checked for leaks, and the drum measured for wear or scoring. On disc rear brakes, the rotor hat should be cleaned and the shoe contact points lightly lubricated with high-temp brake grease—keeping any lubricant well away from the linings.

Common signs it’s time to act include:

• Weak handbrake on hills or excessive lever travel
• Scraping or grinding from the rear at low speed
• Burnt smell or hot rear wheel after a drive (possible dragging)

In normal Aussie and Kiwi driving, parking brake shoes often last well beyond 80,000–120,000 km, while service drum shoes vary with terrain and load. After installing new shoes, bedding-in with gentle stops and a few firm handbrake applications at low speed helps seat the linings. Final quick tip: replace shoes in axle sets, and if a drum or rotor hat has a heavy lip or out-of-round, machine or replace it so the new shoes wear evenly and the handbrake bites properly.

• How can someone tell if their 2010 Impreza has rear drums or rear discs?
  Peeking through the rear wheel usually does it: a shiny rotor and caliper means rear discs, a closed drum face suggests drums. Many ANZ-market Imprezas run rear discs with an internal handbrake shoe, while some base trims in other markets used rear drums. A rego plate lookup or VIN-based parts check can confirm the exact setup.
• How often should brake shoes be replaced?
  There’s no fixed interval. Inspect at regular services, replace when linings near about 1.5 mm, are contaminated, cracked or glazed, or when the handbrake won’t hold properly even after adjustment. Parking brake shoes commonly last 80,000–120,000 km or more, but usage and terrain matter.
• Are parking brake shoes the same as drum brake shoes?
  They’re similar in concept but serve different roles. On disc-brake cars they only hold the vehicle when parked and are smaller, on drum-brake cars they provide everyday stopping at the rear. Each uses different friction lining specs and hardware.
