Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts using a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Compare new pads with old pads to ensure proper size.
Apply brake grease to the back of new brake pads to reduce noise.
Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Check rotor surface for scoring; if damaged, remove the rotor.
Unscrew the rotor retaining screws (if applicable) and pull the rotor off.
Clean the hub surface with a wire brush to remove rust or debris.
Install the new rotor, ensuring it is properly seated.
Tighten rotor retaining screws to manufacturer specifications.

5. Reassemble Braking System

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.

6. Final Checks

Pump the brake pedal a few times to seat the brake pads.
Check brake fluid level and top off if necessary.
