Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Replace Brake Components

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Use a lug wrench to remove the wheel.
Inspect Brake Pads and Rotors:
- Check the thickness of brake pads; replace if below 3mm.
- Inspect rotors for warping or scoring; replace if necessary.
- Clean the rotor surfaces with brake cleaner.
Inspect Brake Calipers:
- Check caliper movement; they should slide freely on their guide pins.
- If calipers are seized or sticking, replace them.
Replace Brake Pads:
- Use a brake pad spreader to compress the caliper piston.
- Install new brake pads ensuring they are properly seated.
- Reassemble caliper and torque bolts to manufacturer specifications (consult repair manual for specific torque values).

3. Check Suspension Components

Visual Inspection:
- Look for signs of wear on control arms and bushings.
- Check for any play in the suspension components.
Replace Worn Components:
- If any components are damaged, replace them accordingly.
- Ensure all bolts are torqued to specifications.

4. Tire and Alignment Check

Tire Inspection:
- Check tire pressure and condition; replace any damaged tires.
- Ensure all tires are evenly worn and properly inflated.
Alignment Adjustment:
- Take the vehicle to a qualified technician for a 4-wheel alignment.
- Ensure alignment settings are adjusted to manufacturer specifications.
