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 avoid electrical issues.

2. Inspect and Replace Brake Rotors

Inspect Rotors:
- Remove the wheel using a socket set.
- Check the rotor surface for scoring or warping using a straight edge.
Replace Rotors:
- If warped, remove the caliper by unscrewing the caliper bolts with a torque wrench.
- Slide the caliper off and secure it (do not let it hang by the brake line).
- Remove the rotor retaining screws (if applicable) and slide the rotor off.
- Install the new rotor, securing it with screws.
- Reattach the caliper and torque bolts to the manufacturer’s specifications.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the pads for thickness (minimum thickness is typically 3mm).
Replace Brake Pads:
- If worn, remove the caliper bracket by unscrewing the bolts.
- Remove the old pads from the bracket.
- Clean the bracket and apply brake grease to the contact points.
- Install new brake pads and reattach the caliper bracket, tightening to specifications.

4. Check Suspension Components

Inspect Suspension:
- Visually inspect control arms, bushings, and struts for wear and damage.
- Replace any worn components as necessary.

5. Wheel Alignment and Balance

Check Alignment:
- Take the vehicle to a professional for alignment and balancing.
- Ensure all wheels are balanced properly to avoid vibrations.
