Solution

1. Preparation

Tools Required: Socket set, wrench set, brake cleaner, brake grease, jack stands, and lug wrench.
Instructions:
- Park the vehicle on a level surface and engage the parking brake.
- Disconnect the negative battery terminal to prevent accidental electrical shocks.
- Loosen the lug nuts on the wheel with the affected caliper.

2. Remove Wheel

Instructions:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the lug nuts completely and take off the wheel to access the brake caliper.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench.
Instructions:
- Locate the caliper mounting bolts and remove them using a socket.
- Carefully slide the caliper off the brake rotor. Support the caliper using a bungee cord or rope to avoid straining the brake line.
- Inspect the caliper for damage or wear.

4. Inspect and Replace Components

Instructions:
- Check the caliper piston for corrosion or sticking. If necessary, replace the caliper.
- Replace the brake pads if they are worn beyond the recommended thickness (usually below 3 mm).
- Ensure the brake rotor is free from grooves and scoring; replace if necessary.

5. Reassemble

Instructions:
- Apply brake grease to the caliper bolts and slide pins to ensure smooth operation.
- Reinstall the caliper over the rotor and tighten the mounting bolts to the manufacturer's torque specifications.
- Reattach the wheel and hand-tighten the lug nuts.

6. Final Steps

Instructions:
- Lower the vehicle from the jack stands and tighten the lug nuts in a star pattern to ensure even pressure.
- Reconnect the negative battery terminal.
- Pump the brake pedal several times to seat the brake pads against the rotor.
