Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues while working.

2. Remove Wheel

Sub-steps:
- Loosen lug nuts with a lug wrench before lifting the vehicle.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the brake caliper by loosening the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar device to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper for any signs of damage or leaks.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Resurface or Replace Rotors

Sub-steps:
- Check the rotor surface for any grooves or warping.
- If the rotor is within specifications, it can be resurfaced; otherwise, replace with new rotors.
- If replacing, remove the rotor by removing the retaining screws and sliding it off the hub.
- Install the new or resurfaced rotor onto the hub and secure with retaining screws.

5. Reassemble Braking System

Sub-steps:
- Reinstall the brake caliper over the new pads and rotor.
- Torque caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).
- Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Sub-steps:
- Lower the vehicle and remove jack stands.
- Tighten lug nuts to the proper torque specification (typically 75-80 ft-lbs).
- Reconnect the negative battery terminal.
