Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

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

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Carefully slide the caliper off the rotor without disconnecting the brake line.
- Inspect the brake pads for thickness; replace if they are less than 1/8 inch.
Brake Rotors:
- Check for any scoring or warping; if damaged, replace the rotor.
- If the rotor is within specifications, consider resurfacing if necessary.

4. Replace Brake Pads/Rotors (if needed)

Install new brake pads or rotors.
Apply anti-squeal lubricant to the backing of the brake pads.
Reinstall the caliper and torque the caliper bolts to manufacturer's specifications (typically around 20-30 ft-lbs).

5. Reassemble and Test

Reattach the wheel and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Lower the vehicle and remove jack stands.
Test the brake pedal for proper function before driving.
