  Q: How to inspect and replace brake discs?

  A: To inspect, remove, and install brake discs, follow these steps. Begin by loosening the wheel lug nuts, raising the vehicle, and securing it on jack stands. Remove the wheel. Remove the Brake Caliper, suspending it with wire and avoiding any stress or twisting of the hose. Detach the hose/line bracket from the steering knuckle for the front brakes. Install two lug nuts with washers to hold the disc against the hub. Visually inspect the disc surface for damage and check for disc run-out using a dial indicator. Ensure the disc thickness meets the minimum refinish thickness. For removal, on floating-type calipers, remove the caliper mounting bracket. Mark the disc in relation to the hub and remove the disc, using a mallet if necessary or using bolts on 2WD models to free a stuck disc. For installation, clean the hub flange and inside of the brake disc, then install the disc onto the hub assembly. On floating-type calipers, install the caliper mounting bracket, Brake Pad Set, and caliper, tightening all mounting bolts to specifications. On fixed-type calipers, install the caliper and brake pads, tightening the caliper mounting bolts. Install the wheel, lower the vehicle, and tighten the wheel lug nuts. Depress the brake pedal to bring the pads into contact with the disc. Bleeding the brake lines is not necessary unless the hose/line was disconnected. Carefully test the brake operation before resuming normal vehicle use. By following these steps, you can inspect, remove, and install brake discs effectively.

  Q: How to inspect, remove and install the Brake Disc?

  A: To inspect the brakes, start by loosening the wheel lug nuts and raising the front of the vehicle on jackstands. Remove the wheel and reinstall the lug nuts on 4WD Tacoma and all 4Runner models to hold the Brake Disc in place. Next, remove the Brake Caliper and suspend it out of the way with wire. Visually inspect the disc surface for damage, such as score marks or deep grooves. Light scratches and shallow grooves are normal, but deep grooves require disc removal and refinishing. Check both sides of the disc. Use a dial indicator to check disc runout and if it exceeds the maximum limit, the disc should be refinished. Measure the disc thickness with a micrometer and ensure it is not less than the specified minimum thickness. To remove and install the disc, follow the specific steps for each model. Clean, inspect, and repack the wheel bearings while the disc/hub assembly is removed. Tighten the disc-to-hub bolts if applicable. Reassemble the hub for 4WD T100 models. Install the disc/hub assembly and adjust the wheel bearings. Install the torque plate, Brake Pad Set, and caliper for 2WD pick-up models. For 4WD pick-ups and all 4Runner models, install the caliper, brake pads, and bleed the brakes. Finally, remove the jackstands and lower the vehicle.
