Solution

1. Preparation

Gather tools and parts:
- Tools: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a caliper tool.
- Parts: New brake pads, brake rotors (if needed), caliper guide pins.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Raise Vehicle and Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to raise the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord or similar tool to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper guide pins and replace if necessary.
Apply brake cleaner to the caliper and rotor to remove debris.
Install new brake pads in the caliper bracket.

4. Reassemble and Adjust

Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
Torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.

5. Final Checks

Pump the brake pedal to ensure the pads seat properly against the rotors.
Check brake fluid level and top off if necessary.
