Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake pad spreader.
Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; do not strain the brake line.
If pads are worn below the minimum thickness (usually 3 mm), replace them.
Install new brake pads into the caliper bracket, ensuring proper orientation.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotors for scoring or excessive wear.
If replacement is necessary, remove the rotor by unscrewing the retaining screws or tapping gently with a hammer.
Clean the hub surface to ensure proper contact with the new rotor.
Install the new rotor and secure it with the retaining screws.

5. Reassemble and Test

Reinstall the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (usually 25-35 ft-lbs).
Reattach the wheel and torque the lug nuts in a star pattern to the specified torque (typically 76 ft-lbs).
Lower the vehicle and perform a brake test before driving to ensure proper operation.
