Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a level surface and engage the parking brake.

2. Remove Wheel

Loosen the lug nuts with a lug wrench while the vehicle is on the ground.
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

Check the thickness of the brake pads; if below 3mm, they need replacement.
Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor, supporting it to avoid strain on the brake line.
Remove the old brake pads from the caliper bracket.
Install new brake pads in the same orientation as the old ones.
Reattach the caliper over the new pads and secure it with bolts, tightening to manufacturer specifications (typically 20-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or worn unevenly, remove the caliper bracket by unscrewing the mounting bolts.
Slide the rotor off the hub; if it’s stuck, tap gently with a mallet.
Install new rotors, ensuring they are clean and free of oil.
Reattach the caliper bracket and secure it with bolts, tightening to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and tighten lug nuts in a star pattern to the specified torque (typically 75-85 ft-lbs).
Pump the brake pedal several times to seat the brake pads.
