Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, rotor measuring gauge, and brake cleaner.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheels using a lug wrench.

2. Inspect Brake Rotors

Remove the caliper by unbolting it from the rotor.
Sub-steps:
- Carefully hang the caliper using a wire or bungee cord to avoid stress on the brake line.
- Measure the rotor thickness using a rotor measuring gauge. Compare with manufacturer specifications.
- Check for signs of warping by placing a straightedge across the rotor and measuring the gap.
If the rotors are warped or below the minimum thickness, proceed to replace them.

3. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Sub-steps:
- Inspect the caliper bracket for wear and clean if necessary.
- Install new brake pads, ensuring they are properly seated in the caliper bracket.
- Apply brake grease to the back of the pads to prevent noise.

4. Reassemble and Torque

Sub-steps:
- Reattach the caliper over the new brake pads and rotor.
- Tighten caliper bolts to the manufacturer’s torque specifications.
- Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

5. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal to seat the pads against the rotors before driving.
