Lexus 42431-48041 Disc, Rear

Before removing the brake disc on these models, activate the parking brake system's "pad replacement mode" using a Toyota Techstream scan tool or equivalent. An alternative method involves unplugging the electrical connector from the parking brake actuators, grounding one terminal on the actuator with a jumper wire, and applying battery voltage to the other terminal while closely monitoring the piston. If the piston extends outward (indicating parking brake application), immediately reverse the connections. Then, remove the lug nuts securing the disc and slide the disc off the hub.

Bleeding is usually unnecessary unless the brake hose was disconnected from the caliper. If installing a rear disc, adjust the parking brake shoes accordingly. Finally, install the wheel and lug nuts, lower the vehicle, and tighten the lug nuts to the specified torque. Depress the brake pedal several times to bring the brake pads into contact with the disc. On 2016 and later Lexus models, apply and release the parking brake multiple times to activate the caliper pistons and position them correctly. Carefully test the brakes' operation before driving the vehicle.
