How to Diagnose or Replace

1. Loosen the lug nuts, lift the corner, and support the CTS on a jack stand.
2. Remove the wheel, then unbolt the caliper bracket from the steering knuckle.
3. Hang the caliper with wire so no weight pulls the flexible brake hose.
4. Slide off the old rotor; back off parking-brake shoes if a rear rotor sticks.
5. Clean the hub face, then mount the new vented rotor onto the studs.
6. Fit new pads, torque the caliper bracket, and reinstall the wheel to spec.
7. Pump the pedal firmly before driving, then bed the pads with gradual stops.

Once diagnosis is complete, order the exact replacement parts for your vehicle - fitment matters. Related Cadillac CTS brake replacement products are listed in the next section.

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

• Torque lug nuts to about 140 lb-ft in a star pattern, then recheck after 50 miles.
• Replace rotors in axle pairs and use fresh caliper hardware to prevent pulsing or pulling.
• Do not resurface the small drum-in-hat parking brake; inspect and replace the shoes only if worn.
