Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brake system.

2. Inspect and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using the lug wrench.
Remove the caliper bolts with a socket set and slide the caliper off the brake rotor.
Inspect the brake pads for wear. If they are below the manufacturer’s specified thickness, replace them.
- Sub-steps for Replacement:
  - Remove old brake pads from the caliper bracket.
  - Clean the caliper bracket using brake cleaner.
  - Install new brake pads ensuring they are properly seated.

3. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if needed).
Check the brake rotors for scoring or warping. If damage is found, proceed with replacement.
- Sub-steps for Replacement:
  - Remove the rotor by taking out the retaining screws if applicable.
  - Install the new rotor ensuring it is securely positioned.
  - Reinstall the caliper over the new rotor.

4. Reassemble and Torque

Reattach the caliper to the bracket and tighten the bolts to the manufacturer’s specified torque settings.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.

5. Final Checks
