Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, safety glasses, gloves.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheels using a lug wrench.

2. Inspect and Replace Brake Pads

Remove Brake Caliper
- Unscrew the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor and secure it with a bungee cord (do not let it hang by the brake line).
Remove Old Brake Pads
- Take note of the orientation, then remove the old brake pads from the caliper bracket.
Install New Brake Pads
- Apply brake grease to the backing plates of the new brake pads to prevent squealing.
- Insert the new brake pads into the caliper bracket in the same orientation as the old ones.

3. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor
- If rotors are damaged, remove the retaining screws (if equipped) and slide the rotor off the hub.
Install New Brake Rotor
- Place the new rotor onto the hub and secure it with retaining screws.

4. Reassemble Brake Components

Reinstall Brake Caliper
- Slide the caliper back over the new brake pads and rotor.
- Tighten the caliper bolts to manufacturer specifications (usually around 20-25 ft-lbs).
Reinstall Wheels
- Place the wheels back on the vehicle and hand-tighten the lug nuts.

5. Final Steps

Lower the vehicle back to the ground.
Torque the lug nuts to the specified value (typically around 80-100 ft-lbs).
