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, if they’re out of round or beyond the maximum diameter spec, replacement is the go. After fitting, the handbrake is adjusted for the correct lever travel, then the shoes are bedded in with a series of gentle, repeated stops from suburban speeds. Avoid blasting dust with compressed air—use approved brake cleaner and a catch tray, and wear a mask.

Typical signs it’s time to book the bB in include longer pedal travel, reduced handbrake hold on hills, scraping or squealing from the rear, a grabbing feel at low speed, or brake fluid tracking from a wheel cylinder. With the right parts and setup, rear drum brakes on the bB are quiet, consistent, and reliable for many kilometres.

• Inspect rear drums/shoes every 20,000 km or 12 months
• Replace shoes in pairs and renew hardware
• Clean and lubricate adjusters and contact points
• Measure drums and replace if beyond spec
• Adjust handbrake and bed-in new linings

Popular questions about 2013 Toyota bB brake shoes

Does the 2013 Toyota bB use rear brake shoes or discs?
Yes—Toyota’s EPC for the QNC20/QNC21 series shows a rear drum brake with shoe kits and associated hardware. The fronts are disc brakes with pads, the rears are drums with shoes and an automatic adjuster, integrating with the handbrake.

How often should the rear brake shoes be replaced?
There’s no fixed kilometre figure because it depends on driving style and conditions. Many owners see 60,000–120,000 km from a set, but the key is inspection every 20,000 km or 12 months. Replace when the linings are near the service limit, contaminated, cracked, or if the hardware’s fatigued.

What are the signs the rear brake shoes need attention?
Look out for longer pedal travel, poor handbrake holding on hills, scraping or squeal from the rear, uneven braking or a grabbing feel at low speeds, and any fluid around the wheel cylinders. If any of these show up, get the drums off for a proper check.
