Solution

1. Preparation

Gather necessary tools and park the vehicle on a level surface.
Ensure the vehicle is in "Park" mode and engage the parking brake.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheel lug nuts with a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Check the brake pads for wear; if less than 3mm thick, they should be replaced.
Replacement:
1. Remove caliper bolts using a socket wrench, and carefully slide the caliper off the rotor.
2. Detach the old brake pads from the caliper bracket.
3. Install new brake pads, ensuring they are properly aligned within the caliper.
4. Reattach the caliper over the new pads and tighten bolts to manufacturer specifications (usually around 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are worn or damaged:
1. Remove the caliper and then the caliper bracket.
2. Slide the rotor off the hub; if it’s stuck, gently tap with a rubber mallet.
3. Install new rotors, ensuring they are clean and free of grease.
4. Reattach the caliper bracket and caliper.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads before driving.
