Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Disconnect the battery for safety.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use a jack to lift the vehicle and secure it on jack stands.
- Use a socket set to remove the lug nuts and take off the wheel.
Inspect Brake Pads
- Look for signs of wear, such as thin material or uneven surfaces.
- If worn below the minimum thickness (usually 3mm), replace them.
Replace Brake Pads
- Remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and hang it using a wire to avoid stress on the brake line.
- Remove the old pads and install new ones, ensuring proper alignment.
- Reattach the caliper and torque bolts to manufacturer specifications (typically around 20-30 ft-lbs).

3. Inspect and Replace Brake Rotors

Check Rotor Condition
- Using a dial indicator, measure rotor runout to check for warping.
- If the runout exceeds manufacturer specifications (usually 0.002 inches), replace the rotor.
Replace Rotors
- Remove the caliper bracket if necessary.
- Take off the rotor by removing screws or retaining clips.
- Install the new rotor and secure it, ensuring proper torque specifications (typically 10-15 ft-lbs for screws).

4. Check Suspension and Alignment

Inspect Suspension Components
- Check for worn bushings, control arms, or tie rods.
- Replace any damaged components before realigning the vehicle.
Perform Wheel Alignment
- Use an alignment tool to ensure proper angles are met.
- Adjust as necessary to manufacturer specifications.
