How to Diagnose or Replace

1. Loosen the five lug nuts, raise the corner, and support the Blazer on a rated jack stand.
2. For rear brakes, put the electronic parking brake into service mode with a scan tool first.
3. Remove the wheel, unbolt the caliper guide pins, and hang the caliper without straining the hose.
4. Slide out the old pads, unbolt the caliper bracket, and pull the rotor off the hub.
5. Clean the hub face, mount the new rotor, and torque the bracket bolts to factory spec.
6. Compress the piston, fit new pads, and reinstall the caliper on its guide pins.
7. Torque lugs to 140 lb-ft in a star pattern, exit EPB service mode, then bed brakes.

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

• Never retract the rear EPB pistons by hand; use the scan-tool service mode or you will damage the actuator.
• Torque lug nuts to 140 lb-ft in a star pattern, then re-check them after about 50 miles.
• Bed new pads with 8 to 10 moderate stops from 40 mph, avoiding a hard stop while hot.
