Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical issues while working on the braking system.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness of the brake pads. If they are less than 3mm, they should be replaced.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it using a bungee cord or mechanic's wire.
Replace Brake Pads:
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are properly seated in the bracket.

4. Inspect and Replace Brake Rotors

Inspect Rotors:
- Check for scoring or warping. If damaged, replace the rotors.
Remove Rotors:
- If necessary, remove the caliper bracket to access the rotor.
- Remove any retaining screws and slide the rotor off the hub.
Install New Rotors:
- Place the new rotor on the hub and secure it with retaining screws if applicable.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper mounting bolts to the manufacturer’s specified torque (typically around 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a crisscross pattern to the recommended torque.

6. Final Steps

Reconnect the battery.
Pump the brake pedal a few times to ensure the brake pads seat properly and restore brake pedal feel.
