How to Diagnose or Replace
- Loosen the five lug nuts, then raise the corner and set it on a jack stand.
- Remove the wheel to expose the caliper, mounting bracket, and vented rotor.
- Unbolt the two caliper slide bolts and hang the caliper aside on wire.
- Remove the two bracket bolts, then slide off the worn pads and rotor.
- Clean the hub face, fit the new rotor, and torque bracket bolts to spec.
- Compress the piston, install new pads and hardware, then reinstall the caliper.
- Mount the wheel, torque lugs to 76 lb-ft, and pump the pedal firm before driving.

Cost Breakdown - DIY vs Shop
| Job | DIY parts only | Shop parts and labor |
|---|---|---|
| Front brake pads | Axle set | $40-$90 |
| Rear brake pads | Axle set | $35-$80 |
| Rotors | Per pair | $80-$220 |
| Full 4-wheel job | Shop labor plus parts | $500-$1,000+ |
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
- Torque lug nuts to 76 lb-ft in a star pattern, then recheck after about 50 miles.
- Bed new pads with 8 to 10 moderate 40-to-10 mph stops before any hard braking.
- Support the caliper on wire so its weight never hangs on the flexible brake hose.
