How to inspect and replace a brake disc on Toyota Sienna?

Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and install the lug nuts to hold the disc in place, releasing the parking brake if working on the rear brake disc. Remove the brake caliper without disconnecting the brake hose, suspending it out of the way with a piece of wire to avoid hanging it by the flexible brake hose. Detach the torque plate by removing its mounting bolts. Visually inspect the disc surface for score marks and damage; light scratches are normal, but deep scoring over 0.039-inch requires disc removal and refinishing. Check both sides of the disc, and if pulsating occurs during braking, suspect disc runout. To check runout, place a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc, ensuring the reading does not exceed the allowable limit. Discs should be resurfaced to ensure a smooth finish and flat surface, eliminating brake pedal pulsation. If not resurfaced, remove any glaze with sandpaper or emery cloth using a swirling motion. Ensure the disc is not machined below the minimum allowable refinish thickness, which is cast into the inside of the disc, and measure the thickness with a micrometer. Remove the lug nuts used to hold the disc in place and take the disc off the hub. Place the new disc over the threaded studs, install the torque plate, and tighten the bolts to the specified torque. Install the caliper and tighten its bolts, bleeding the system only if the brake hose was disconnected. Finally, install the wheel and lug nuts, lower the vehicle, tighten the lug nuts to the specified torque, and depress the brake pedal a few times to bring the brake pads into contact with the disc, checking the operation of the brakes carefully before driving.

Q: How to inspect and replace a brake disc on Toyota Sienna?
A: Loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the wheel and install the lug nuts to hold the disc in place, releasing the parking brake if working on the rear brake disc. Remove the Brake Caliper without disconnecting the brake hose, suspending it out of the way with a piece of wire to avoid hanging it by the flexible brake hose. Detach the torque plate by removing its mounting bolts. Visually inspect the disc surface for score marks and damage; light scratches are normal, but deep scoring over 0.039-inch requires disc removal and refinishing. Check both sides of the disc, and if pulsating occurs during braking, suspect disc runout. To check runout, place a dial indicator about 1/2-inch from the outer edge of the disc, set it to zero, and turn the disc, ensuring the reading does not exceed the allowable limit. Discs should be resurfaced to ensure a smooth finish and flat surface, eliminating brake pedal pulsation. If not resurfaced, remove any glaze with sandpaper or emery cloth using a swirling motion. Ensure the disc is not machined below the minimum allowable refinish thickness, which is cast into the inside of the disc, and measure the thickness with a micrometer. Remove the lug nuts used to hold the disc in place and take the disc off the hub. Place the new disc over the threaded studs, install the torque plate, and tighten the bolts to the specified torque. Install the caliper and tighten its bolts, bleeding the system only if the brake hose was disconnected. Finally, install the wheel and lug nuts, lower the vehicle, tighten the lug nuts to the specified torque, and depress the brake pedal a few times to bring the brake pads into contact with the disc, checking the operation of the brakes carefully before driving.
