Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Brake Pads

Remove the wheel:
- Use a lug wrench to loosen lug nuts.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the wheel.
Inspect brake pads:
- Check thickness; replace if less than 3mm.
- Look for uneven wear patterns.
Install new brake pads:
- Remove caliper bolts with a socket set.
- Slide the caliper off and replace old pads with new ones.
- Reassemble caliper and securely tighten bolts to manufacturer's specifications (usually around 25 Nm).

3. Inspect and Replace Brake Rotors (if necessary)

Check rotor condition:
- Use a dial indicator to measure warping.
- If warped beyond specifications (usually 0.002 inches), replace rotors.
Remove old rotors:
- Remove caliper and bracket as per previous step.
- Unscrew the rotor retaining screws and slide off the rotor.
Install new rotors:
- Clean the new rotor with brake cleaner.
- Install the new rotor and secure it with retaining screws.
- Reattach caliper assembly and tighten to specifications.

4. Inspect Suspension Components

Check for wear:
- Look for any cracks or excessive play in bushings and control arms.
- Replace any damaged components as needed.

5. Wheel Alignment and Tire Balance

Check alignment:
- Use an alignment tool or take the vehicle to a professional service.
- Adjust alignment as necessary.
Balance tires:
- Mount tires on a balancing machine and adjust weights as needed.
