Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Remove the Wheel

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

3. Inspect and Replace Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and hang it with a bungee cord or similar to avoid strain on the brake line.
- Remove the old brake pads and inspect for wear. Replace with new pads if necessary.
Brake Rotors:
- If rotors are damaged, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
- Install new rotors, ensuring they are clean and free from grease.
Calipers:
- Inspect the caliper pistons for corrosion or damage. If they are damaged, replace the caliper.

4. Reassemble Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to the manufacturer's specified torque (usually around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a criss-cross pattern to the specified torque.

5. Final Steps

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads properly.
