Parts for your 2009 Toyota Bb-Brake shoes

2009 Toyota bB brake-shoes — what they do and when to replace them

Brake-shoes are relevant to the 2009 Toyota bB. Technical references including the Toyota bB (QNC20/QNC21) Repair Manual (Section BR: Rear Brake — Drum) and Toyota’s Electronic Parts Catalogue for the QNC2# series specify a rear drum brake assembly that uses leading–trailing brake-shoes on most trims of this model year. Industry data used by workshops (e.g., Autodata-style spec listings commonly used across AU/NZ) also shows front discs with rear drums for the 1.3L and 1.5L bB, confirming the use of brake-shoes at the rear.

On this bB, the rear brake-shoes sit inside the drums. When the pedal’s pressed, the wheel cylinders push the shoes outwards so their friction lining bites the drum’s inner surface, slowing the car and doubling as the parking brake mechanism. They’re simple, durable and well-suited to everyday city use, which is why Toyota kept drums with shoes on the back.

For servicing, the aim is clean, correctly adjusted, leak-free drums with plenty of lining on the shoes. A good workshop will remove the drums, measure shoe lining thickness, check for heat spots and out-of-round drums, inspect and clean the self-adjusters, lightly lube shoe contact points with the correct high-temp brake grease, and confirm parking brake operation. Wheel cylinders should be checked for seepage and smooth piston movement, and brake fluid replaced on schedule (typically every 2 years) to keep internal corrosion at bay.

Replacement intervals vary with driving style, load and terrain. As a guide, have the rear drums opened for inspection every 20,000 km or at least once a year. Replace brake-shoes as an axle set if the lining is near the manufacturer’s minimum (often around 1.5–2.0 mm), if they’re contaminated with fluid/grease, or if the friction material is cracked or glazed. Always bed-in new shoes with gentle stops over the first 200–300 km.

• Watch for tell-tales: longer stopping distances, a higher or uneven handbrake lever, scraping/squealing from the rear, or a soft pedal.
• Consider new fitting hardware (springs/clips) with the shoes
