Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, brake rotor removal tool.
Sub-steps:
1. Remove the wheel by loosening the lug nuts with a socket set.
2. Inspect the brake rotor using a dial indicator; if warped beyond manufacturer specifications (usually over 0.003 inches), replace the rotor.
3. Remove the caliper bolts and slide the caliper off; support it with a bungee cord to avoid stress on the brake line.
4. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
5. Install the new rotor, ensuring it is seated properly against the hub.
6. Reinstall the caliper and torque bolts to manufacturer specifications (typically around 80-100 ft-lbs).
7. Reinstall the wheel and torque lug nuts to the correct specification (usually around 75-85 ft-lbs).

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader tool, socket set.
Sub-steps:
1. With the caliper removed, inspect the brake pads for thickness; replace if less than 3mm.
2. Remove old pads by sliding them out of the caliper bracket.
3. Use a brake pad spreader tool to compress the caliper piston before installing new pads.
4. Install new brake pads into the caliper bracket, ensuring they are correctly aligned.
5. Reattach the caliper and torque to manufacturer specifications.

4. Suspension Component Inspection

Tools Required: Jack, jack stands, socket set.
Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Inspect suspension components (tie rods, ball joints, control arms) for play or wear.
3. Replace any damaged or worn components with OEM parts.
