Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Remove Wheel

Loosen the lug nuts on the wheel using a lug wrench.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Remove the brake caliper by unbolting it from the mounting bracket using a socket set.
- Tools Required: Socket set, torque wrench
Carefully hang the caliper using a wire or bungee cord to avoid straining the brake line.
Remove the brake pads from the caliper bracket.
Unbolt the rotor from the hub if it is secured with screws; otherwise, slide it off.
Install new brake rotors, ensuring they are properly aligned.
- Torque Specification: Consult the vehicle’s service manual for the correct torque values for the rotor bolts.

4. Install New Brake Pads

Apply brake grease to the back of the new brake pads to reduce squeaking.
Insert the new brake pads into the caliper bracket.
Reattach the brake caliper over the new pads and secure it with bolts.
- Torque Specification: Again, refer to the service manual for proper torque specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten the lug nuts to the specified torque.
Reconnect the battery.
Pump the brake pedal a few times to seat the pads against the rotors.
