Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the battery to avoid any electrical issues during the procedure.

2. Remove Wheel Assembly

Use a lug wrench to loosen and remove the wheel nuts.
Remove the wheel to access the brake assembly.
Inspect the brake assembly for any visible issues.

3. Remove Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor. Do not let it hang from the brake line; use a bungee cord or similar to support it.
Remove the old brake pads from the caliper bracket.

4. Inspect and Clean Components

Check the caliper slides for corrosion or debris; clean them with brake cleaner.
Inspect the brake rotor for warping or damage, replacing if necessary.
Ensure the caliper piston moves freely; if it’s stuck, consider replacing the caliper.

5. Install New Brake Pads

Apply brake grease to the backing of the new pads to prevent noise and ensure smooth operation.
Install the new brake pads into the caliper bracket.
Reposition the caliper over the new pads and secure it with mounting bolts, tightening to manufacturer specifications (usually 20-25 lb-ft).

6. Reassemble and Test

Reinstall the wheel and tighten the lug nuts in a star pattern.
Lower the vehicle and reconnect the battery.
Pump the brake pedal a few times to seat the pads against the rotor.
