Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Lift the vehicle using a jack and secure with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Check brake pad thickness; if worn below 3mm, replace.
Remove the caliper by unscrewing the caliper mounting bolts with a socket.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove old brake pads from the caliper bracket.
Install new brake pads into the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if needed)

Check rotor for grooves or excessive wear; replace if necessary.
Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
Clean the mounting surface with brake cleaner to remove debris.
Install new rotor, ensuring it is aligned correctly.

5. Reassemble Components

Reattach the caliper over the new brake pads and rotor.
Torque caliper mounting bolts to the manufacturer's specifications (check your repair manual for exact torque values).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle to the ground and remove jack stands.
Tighten the lug nuts to the specified torque in a star pattern.
Pump the brake pedal several times to seat the pads against the rotor.
