Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves throughout the repair process.

2. Brake Pad and Rotor Replacement

Remove the Wheel
- Use a lug wrench to loosen lug nuts and remove the wheel.
- Tools Required: Lug wrench, jack stands, jack.
Inspect and Remove Brake Caliper
- Remove caliper mounting bolts using a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord or similar tool.
- Tools Required: Socket set, bungee cord.
Remove and Inspect Brake Rotor
- Remove the rotor if it is warped or worn beyond specifications.
- Check for any score marks or uneven surfaces. If needed, replace the rotor.
- Tools Required: Hammer (if rotor is stuck), socket set.
Install New Brake Rotors (if needed)
- Clean the new rotor with brake cleaner to remove any protective coating.
- Install the new rotor onto the hub.
- Torque to manufacturer specifications (typically 75-100 ft-lb).
- Tools Required: Torque wrench.
Install New Brake Pads
- Apply anti-squeal lubricant to the back of the new brake pads.
- Insert new brake pads into the caliper bracket.
- Reinstall the caliper and torque bolts to manufacturer specifications.
- Tools Required: Torque wrench, anti-squeal lubricant.
Reinstall the Wheel
- Place the wheel back on and hand-tighten lug nuts.
- Lower the vehicle and torque lug nuts to manufacturer specifications (usually 75-80 ft-lb).
- Tools Required: Torque wrench.

3. Check and Adjust Suspension Components

Inspect Suspension Parts
- Look for worn bushings, control arms, and tie rods.
- Replace any damaged components.
- Tools Required: Socket set, pry bar.
Alignment Check
- Perform a wheel alignment if suspension components were adjusted or replaced.
- Tools Required: Alignment rack (professional service).
