Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely supported with jack stands.
Disconnect the negative battery terminal.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Locate the brake caliper and remove the caliper bolts with a socket wrench.
3. Carefully slide the caliper off the rotor and support it without straining the brake line.
4. Remove the old brake pads from the caliper bracket.
5. Compare the old pads with new ones to ensure proper fit.
6. Apply brake grease to the back of the new pads to reduce noise and prevent sticking.
7. Install the new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check rotor thickness with a micrometer; replace if below minimum specifications.
2. If rotors are damaged, remove them by unscrewing the retaining screws and sliding them off the hub.
3. Install new rotors, ensuring they are clean and free of oil.
4. Torque the retaining screws to manufacturer specifications.

4. Reassemble Brake System

Sub-steps:
1. Reattach the brake caliper to the bracket and tighten caliper bolts to the specified torque.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specification.

5. Final Steps

Reconnect the negative battery terminal.
Pump the brake pedal to seat the pads against the rotors.
Check brake fluid levels and top up if necessary.

Tools Required:
