Will the dashboard display a warning when the Corolla's brake pads need replacement?

The dashboard of the Corolla will display a warning when the brake pads need replacement, showing a brake warning light with an exclamation mark inside a circle. Taking the 2021 Corolla as an example, it belongs to the compact car category with body dimensions of 4635mm in length, 1780mm in width, and 1455mm in height, a wheelbase of 2700mm, a fuel tank capacity of 50 liters, and a trunk capacity of 470 liters. The 2021 Corolla features a MacPherson strut front suspension and an E-type multi-link rear independent suspension. It is equipped with a 1.2T turbocharged engine delivering a maximum horsepower of 116PS, a maximum power of 85kW, and a maximum torque of 185Nm, paired with a 10-speed continuously variable transmission.
It depends on the year of your Corolla. Newer models, like those from 2020 onwards, often come with brake pad wear indicators. When the brake pads wear down to the limit, a yellow exclamation mark icon will pop up on the dashboard, along with a text reminder telling you it's time to replace them. However, older Corolla models, like my 2015 one, don't have this feature at all. Even if there is a warning, don't rely on it too much. Last time I went for maintenance, the mechanic said that by the time the sensor alerts you, the brake pads are usually down to the metal, which can damage the brake discs and be dangerous. It's best to check the brake pad thickness yourself every 20,000 kilometers by taking a peek behind the tires. If it's below 3mm, replace them immediately to avoid a sudden breakdown scare.
I've been repairing Corollas for ten years, and dashboard warnings depend on the situation. The newer hybrid versions and high-end models usually have brake pad alerts, but most mid to low-end models don't. The alert works via a metal sensor embedded in the brake pad—when worn to the limit, it contacts the brake disc, completes the circuit, and lights up the dashboard. The key is not to wait for the alert. Last time, an owner came only after the light came on, and we found deep grooves worn into the brake disc, costing an extra 800 for a replacement. I recommend having the mechanic measure the thickness with a special caliper during every service—it's much more reliable than the dashboard. Also, pay attention to sounds while driving; if the brakes squeal sharply, they should be replaced even without an alert.
