Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues during repair work.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel by loosening the lug nuts with a socket set.
2. Use a jack to lift the vehicle and secure it on jack stands.
3. Remove the brake caliper by unbolting it (usually two bolts).
4. Slide the caliper off the rotor and secure it using a bungee cord to avoid straining the brake line.
5. Remove the old brake pads from the caliper bracket.
6. Inspect the caliper bracket and clean it of any dust or debris.
7. Install new brake pads, ensuring they match the old ones in size and type.
8. Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-35 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are scored or warped, remove the rotors by unbolting the rotor retaining screws (if equipped).
2. Clean the hub surface to ensure proper rotor seating.
3. Install new rotors and secure them with the retaining screws.
4. Reinstall the brake caliper and pads, following the previous steps.

4. Brake System Reassembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and tighten the lug nuts to the recommended torque (usually 75-85 ft-lbs).
3. Reconnect the battery.
