Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, wire brush, torque wrench, safety goggles, gloves.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the brake rotor. Support it with a bungee cord or rope to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Clean the caliper bracket and rotor with brake cleaner and a wire brush to remove any debris or dust.
5. Install new brake pads in the caliper bracket, ensuring they are properly seated.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor for damage; if warped or scored, proceed to replacement.
2. Remove the caliper bracket using a socket set.
3. Slide the rotor off the wheel hub. If it’s stuck, gently tap it with a rubber mallet.
4. Install the new rotor by sliding it onto the wheel hub.
5. Reinstall the caliper bracket, tightening bolts to the manufacturer’s torque specifications (usually around 30-45 ft-lbs).

4. Reassemble and Test

Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Reattach caliper bolts and tighten them to manufacturer specifications.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 80-90 ft-lbs).
