How to Diagnose or Replace

1. Loosen the lug nuts, raise the car, secure it on jack stands, then remove the wheels.
2. Activate the electronic parking brake's maintenance mode with a scan tool before servicing the rear brakes.
3. Unbolt the caliper guide pins, pivot the caliper upward, and slide out the worn pads.
4. Compress front pistons with a C-clamp; retract rear EPB pistons electronically, never forcing them by hand.
5. Remove the two caliper bracket bolts, then pull the rotor off the wheel hub.
6. Install new rotors and pads, refit the calipers, and torque bracket bolts to factory spec.
7. Exit maintenance mode, torque lug nuts to 80 lb-ft, then pump the pedal firm before driving.

Cost Breakdown - DIY vs Shop

DIY savings scale with vehicle size and job complexity. A full-size truck brake job saves $450-700 in labor. For most passenger cars, plan on 90-120 minutes per axle for pads only, 2-3 hours for pads plus rotors.

Install Tips - Where Most DIYers Go Wrong

• Always retract the electronic parking brake through maintenance mode; forcing the rear pistons back damages the actuator.
• Bed new pads with 8 to 10 moderate 40-to-10 mph stops to transfer even friction material.
• Torque lug nuts to 80 lb-ft in a star pattern and recheck after 50 miles.
