Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection: Examine the brake pads for wear; replace if they are below the manufacturer's minimum thickness.
- Tools Required: Torque wrench, socket set.
Replacement:
1. Remove the caliper bolts using a socket.
2. Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads ensuring they are seated correctly.
5. Reinstall the caliper and torque bolts to specification (typically around 25-35 ft-lbs, check manufacturer specs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspection: Check rotors for warping or surface damage.
Replacement:
1. If rotors are damaged, remove the caliper and bracket as previously noted.
2. Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
3. Install the new rotor and secure with screws.
4. Reinstall the brake caliper and torque to specification.

5. Final Assembly

Reinstall the wheel and lower the vehicle.
Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads.
