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 any electrical issues during repairs.

2. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner, C-clamp.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn below manufacturer's specifications.
- If replacing:
  1. Remove the caliper bolts using a socket.
  2. Slide the caliper off the rotor.
  3. Use a C-clamp to compress the caliper piston.
  4. Replace old pads with new ones.
  5. Reinstall the caliper and torque bolts to manufacturer specifications.

3. Inspect and Replace Brake Rotors

Tools Required: Rotor puller, torque wrench.
Check rotor thickness with a micrometer; replace if below minimum thickness.
If warped, replace:
1. Remove caliper and pads as described above.
2. Remove the rotor by unscrewing the retaining screws (if equipped).
3. Install new rotor and secure it properly.
4. Reinstall caliper and pads.

4. Examine Suspension Components

Tools Required: Jack and jack stands, visual inspection tools.
Lift the vehicle and support with jack stands.
Inspect control arms, bushings, and struts for wear.
- Replace any worn components as necessary.

5. Check Wheel Alignment and Balance

Tools Required: Alignment tools (or take to a professional).
Ensure wheels are balanced and aligned according to manufacturer specifications.
