Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the battery for safety if working on electrical components.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts on the affected wheel while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

Tools Required: Torque wrench, brake cleaner, caliper tool
Inspect the brake pads and rotors for wear. If the rotors are warped or pads are worn down, replace them.
Remove the caliper bolts and carefully slide the caliper off the rotor. Support the caliper with a bungee cord to avoid straining the brake line.
Remove the old brake pads and clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they are seated properly.
If rotors are being replaced, remove the old rotor and install the new rotor, securing it with the appropriate hardware.

4. Reassemble and Torque

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque value.
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Checks

Lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern.
Reconnect the battery if it was disconnected.
Test the brake system by pressing the brake pedal a few times to seat the pads.
