How to Diagnose or Replace

1. Loosen the six lug nuts, lift the corner, and remove the wheel to expose the caliper.
2. For rear brakes, place the Electric Park Brake into service mode using a scan tool first.
3. Remove the two caliper slide bolts, lift the caliper off, and hang it to avoid hose strain.
4. Slide out the old pads, then unbolt the caliper bracket to free the rotor.
5. Fit the new vented front or solid rear rotor onto a clean hub face.
6. Compress the piston, install new pads, and torque caliper bolts to factory specification.
7. Reinstall the wheel, torque lugs near 130 lb-ft, and pump the pedal firm before driving.

Cost Breakdown - DIY vs Shop

Install Tips - Where Most DIYers Go Wrong

• Retract the rear EPB with a scan tool before pad service; never force the piston back.
• Torque lug nuts to about 130 lb-ft in a star pattern after refitting each wheel.
• Bed in new pads and rotors with graduated stops and avoid hard braking for 200 miles.
