Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Loosen the lug nuts on the wheel corresponding to the brake being serviced.

2. Wheel Removal

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Caliper Removal

Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the brake rotor. Suspend it using a bungee cord to avoid stressing the brake line.

4. Brake Pad Inspection and Replacement

Inspect the brake pads for uneven wear. If worn unevenly, replace both inner and outer pads on that axle.
Remove old pads and clean the caliper bracket with brake cleaner.
Apply brake grease to the back of the new pads to prevent noise.
Install the new brake pads ensuring they fit snugly in the caliper bracket.

5. Caliper and Rotor Inspection

Check the rotor for warping or excessive wear. If warped, replace the rotor.
If necessary, resurface the rotor if it meets the manufacturer's specifications.
Ensure caliper slide pins are free of corrosion and properly lubricated.

6. Reinstallation

Reattach the caliper over the new pads and secure it with the mounting bolts. Torque to manufacturer specifications.
Reinstall the wheel and tighten the lug nuts in a star pattern.

7. Final Checks

Lower the vehicle from the jack stands.
Pump the brake pedal to seat the new pads.
Check brake fluid level and top off if necessary.
