Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal.

2. Inspect and Replace Brake Pads

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel lug nuts using a socket set and take off the wheel.
Inspect Brake Pads:
- Check the brake pads for thickness. Replace if less than 3mm.
- Use a brake pad spreader if necessary.
Replace Brake Pads:
- Remove the caliper bolts with a socket.
- Slide the caliper off the rotor.
- Replace the old pads with new ones, ensuring they fit snugly.

3. Inspect and Resurface/Replace Brake Rotors

Check Rotor Condition:
- Look for signs of warping or grooves on the rotor surface.
Resurface or Replace:
- If slightly warped, consider resurfacing the rotors using a lathe.
- If excessively worn or damaged, replace with new rotors.
Reinstall Components:
- Slide the caliper back onto the rotor and secure it with bolts.
- Reinstall the wheel and lug nuts, tightening to the manufacturer’s specifications.

4. Inspect Suspension Components

Check for Damage:
- Look for worn bushings, control arms, or struts in the suspension system.
Replace Components:
- If any components are damaged or worn, replace them following manufacturer guidelines.

5. Final Assembly

Reconnect the negative battery terminal.
Lower the vehicle and torque the lug nuts to specification.
