Solution

1. Preparation

Gather necessary tools and parts.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the braking system.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper bolts using a socket set.
2. Carefully slide the caliper off the brake rotor and suspend it using a bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads ensuring they are oriented correctly and seated properly in the bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are warped or excessively worn, remove them by unscrewing the retaining screws (if applicable) and sliding them off the hub.
2. Install new rotors, ensuring they are clean and free of oil or debris.
3. Torque the rotor screws to manufacturer's specifications.

4. Reassemble Brake Components

Sub-steps:
1. Reattach the caliper over the new brake pads and rotor.
2. Tighten the caliper bolts to the specified torque.
3. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.

5. Brake Fluid and System Check

Sub-steps:
1. Check the brake fluid level and top off if necessary with the appropriate brake fluid (DOT 3 or DOT 4 as specified).
2. Pump the brake pedal several times to seat the new pads and ensure proper pedal feel.
