2
Check the brake rotors for warping or uneven surfaces.
3
Examine the calipers for proper operation and signs of sticking.
4
Inspect the brake hardware for corrosion or damage (shims, clips).

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner.
Park the vehicle on a level surface and engage the parking brake.
Loosen the lug nuts on the wheels where brake work will be performed.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Components

Check Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Carefully slide the caliper off the rotor and secure it (do not hang it from the brake line).
- Inspect the pads for wear; replace if they are unevenly worn.
Check Brake Rotors:
- Measure rotor thickness with a micrometer; replace if worn beyond specifications.
- If the rotor surface is uneven, consider resurfacing or replacing the rotor.
Caliper Inspection:
- Check for caliper movement; ensure it slides freely.
- Replace caliper if it is sticking or damaged.

4. Reassemble

Install new or resurfaced rotors and replace brake pads.
Reattach the caliper and torque the bolts to manufacturer specifications.
Reinstall the wheels and torque the lug nuts to the specified value.

5. Final Checks

Lower the vehicle and perform a brake fluid check; top off if necessary.
Pump the brake pedal to seat the pads before driving.
