Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake pad spreader, caliper tool.
Lift the vehicle using the jack and secure it with jack stands.
Remove the wheel using a lug wrench to access the brake components.

2. Remove Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the bolts securing it using the socket set.
2. Carefully slide the caliper off the brake rotor and support it without stretching the brake line.
3. Remove the old brake pads from the caliper bracket.

3. Inspect and Clean Components

Sub-steps:
1. Inspect the brake rotor for damage; replace if needed.
2. Clean the caliper and bracket using brake cleaner to remove dust and debris.
3. Check the caliper pistons for proper function; compress if necessary using a caliper tool.

4. Install New Brake Pads

Sub-steps:
1. Apply brake grease to the back of the new brake pads to reduce noise.
2. Insert the new brake pads into the caliper bracket.
3. Reattach the caliper over the new pads and secure it with the bolts.

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer’s specifications.
