How to Diagnose or Replace

1. Loosen the six lug nuts, lift the corner, and secure the 4Runner on a jack stand.
2. Remove the wheel, then unbolt the caliper slider bolts and hang the caliper aside.
3. Slide out the old pads and inspect the vented rotor for scoring or heat cracks.
4. Remove the two caliper-bracket bolts, then pull the rotor off the hub studs.
5. For rear rotors, back off the parking-brake shoe adjuster so the drum-in-hat rotor releases.
6. Mount the new rotor, torque the bracket bolts, fit the pads, and reseat the caliper.
7. Torque lug nuts to 83 lb-ft in a star pattern, then bed the brakes gently.

• V8 and Sport Edition trims use the larger 338mm front rotor; verify diameter before ordering.
