Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues while working on the brakes.

2. Remove Wheel

Sub-steps:
- Loosen lug nuts with a socket wrench.
- Raise the vehicle using a jack and secure it with jack stands.
- Completely remove the lug nuts and the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Sub-steps:
- Remove the caliper bolts using the socket wrench.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar device to avoid stressing the brake line.

4. Inspect and Replace Brake Pads

Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper bracket and clean it if necessary.
- Install new brake pads, ensuring they are properly seated in the bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check rotor condition; if warped or excessively worn, proceed with replacement.
- Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Clean the hub surface where the rotor mounts.
- Install the new rotor, ensuring it is properly seated.

6. Reassemble Brake Components

Sub-steps:
- Reposition the caliper over the new pads and rotor.
- Tighten caliper bolts to the manufacturer’s specified torque value.
- Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Tighten the lug nuts to the specified torque in a crisscross pattern.
