Solution

1. Preparation

Tools Needed: Jack, jack stands, lug wrench, torque wrench, brake cleaner, anti-seize lubricant.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the appropriate socket.
2. Carefully slide the caliper off the rotor without stretching the brake line.
3. Remove the old brake pads from the bracket.
4. Inspect the brake pads for wear; replace if they are below the minimum thickness (usually 3mm).
5. Apply brake cleaner to the caliper and rotor to remove dust and debris.
6. Install new brake pads in the bracket, ensuring proper alignment.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or warping.
2. If the rotors are damaged, remove them by unscrewing the retaining screws (if equipped) and sliding them off the hub.
3. Install new rotors, ensuring they are seated properly on the hub.
4. Reinstall caliper over the new pads and rotor.

4. Reassemble and Torque Components

Sub-steps:
1. Reinstall the caliper bolts and torque to manufacturer specifications (typically 30-40 ft-lbs).
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specified torque (usually 100 ft-lbs).

5. Finish Up

Sub-steps:
1. Pump the brake pedal several times to seat the new pads against the rotor.
2. Check brake fluid level and top off if necessary.
3. Dispose of any old brake components properly.
