2013 Toyota bB Brake Shoes — What They Do and When to Replace Them

Based on technical sources used in trade—Toyota’s Electronic Parts Catalog (EPC) for the bB QNC20/QNC21 series (2013 production) and the Toyota Repair Manual sections covering “Rear Drum Brake”—the 2013 Toyota bB is fitted with rear drum brakes that use brake shoes (Toyota PNC 04495, “Shoe Kit, Rear Brake”). These references list the rear brake setup as a leading–trailing drum with shoe hardware, springs, and an automatic adjuster, confirming that brake shoes are relevant and used on this model.

On a 2013 Toyota bB, the brake shoes live inside the rear brake drums. When the driver presses the pedal, hydraulic pressure pushes the shoes outwards against the inner surface of the drum, creating friction to slow the car. They also work with the handbrake to hold the vehicle securely when parked. Being a sealed drum design, they’re generally low-maintenance, but they do wear and the hardware can get tired over time.

For everyday servicing, it’s smart to have the rear drums removed and the shoes inspected about every 20,000 km or 12 months, especially if the car does lots of city kilometres or carries heavier loads. A technician will check lining thickness, glaze, cracking, heat spots on the drum, and any signs of wheel cylinder seepage. If the linings are near the service limit, or the friction material is contaminated with fluid or grease, the shoes should be replaced.

Brake shoes are replaced as an axle set (both sides) to keep braking even. It’s good practice to fit a fresh hardware kit at the same time—return springs, hold-down pins, and the adjuster components lose tension and corrode with age. The backing plate contact points should be cleaned and given a tiny smear of high-temp brake grease, and the star-wheel adjuster threads should be cleaned and lubricated so the automatic adjustment works smoothly. The drums should be measured
