Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, caliper tool, torque wrench, brake cleaner, shop rags.
Safety Warnings: Ensure the vehicle is on a flat surface. Engage the parking brake and wear safety glasses.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake pads and suspend it using a bungee cord or wire to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Note: If pads are uneven, check the caliper slides and ensure they are lubricated and moving freely.

4. Inspect and Replace Rotors (if necessary)

If rotors are warped or excessively worn, remove the caliper bracket (if applicable) by unscrewing the bracket bolts.
Slide the rotor off the hub assembly.
If replacing, install the new rotor and torque bolts to manufacturer specifications.

5. Reassemble Brake Components

Install new brake pads onto the caliper bracket.
Reattach the caliper over the new pads and secure it with bolts, torquing them to the specified value.
Reinstall the wheel and hand-tighten the lug nuts.

6. Finalization

Lower the vehicle and securely tighten the lug nuts in a crisscross pattern to the specified torque.
Pump the brake pedal several times to seat the pads properly.
