Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel using a socket set.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor.
- Check the pads for thickness; if less than 1/8 inch, replace them.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Install new pads, ensuring they are correctly positioned in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are scored or warped:
- Remove the rotor by unscrewing the retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are properly seated.
- Torque the retaining screws to the manufacturer's specifications (usually around 7-10 ft-lbs).

5. Reassemble Braking System

Reinstall the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and torque the lug nuts to the specified value (usually around 80-100 ft-lbs).

6. Final Checks

Reconnect the battery.
Pump the brake pedal to seat the pads against the rotors.
Test the brakes for noise and performance.
