Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel by fully unscrewing the lug nuts.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts.
2. Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it dangle).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of damage or leaks.
5. If worn, install new brake pads ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller (if needed)
Sub-steps:
1. Check the condition of the brake rotors; replace if warped or heavily scored.
2. If replacing, remove the old rotor by unscrewing the retaining screws.
3. Install the new rotor and secure it according to manufacturer specifications.

5. Reassemble Components

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the caliper over the new brake pads and rotor.
2. Tighten the caliper bolts to the manufacturer’s torque specifications.
3. Reattach the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and fully tighten the lug nuts in a star pattern.
