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.
