Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Rotors

Remove the Wheel:
- Use a lug wrench to loosen the lug nuts.
- Raise the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect the Brake Rotors:
- Check the rotor surface for grooves or warping.
- Measure the thickness of the rotors with a micrometer; replace if below manufacturer specifications.
Replace Rotors if Necessary:
- Remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor and suspend it with a bungee cord (do not let it dangle by the brake line).
- Remove the old rotor by unscrewing any retaining screws and sliding it off the hub.
- Install new rotors, ensuring they are properly seated and secured.

3. Inspect and Replace Brake Pads

Remove Old Brake Pads:
- Remove the caliper bracket if necessary.
- Slide out the old brake pads from the caliper.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent squeaking.
- Insert the new pads into the caliper.
Reassemble the Caliper:
- Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

4. Check Suspension Components

Visual Inspection:
- Inspect all suspension components for signs of wear, such as cracks, rust, or looseness.
Replace Any Damaged Components:
- If any components are found to be faulty, replace them following proper disassembly and assembly procedures.

5. Perform Wheel Alignment and Balancing

Alignment Check:
- Take the vehicle to a professional alignment shop to ensure proper wheel alignment.
Wheel Balancing:
- Have the tires balanced to prevent vibrations from unbalanced wheels.
