Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent vehicle movement.

2. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, brake caliper tool, torque wrench
Sub-steps:
1. Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
2. Lift the front of the vehicle using a jack and secure with jack stands.
3. Remove the front wheels to access the brake components.
4. Inspect brake pads for thickness; replace if below 3mm.
5. Check rotors for warping using a dial gauge; replace if warping exceeds manufacturer specifications or if there are deep grooves.
6. If replacing, remove the caliper by unbolting it and hang it using a wire to avoid stress on the brake line.
7. Install new rotors and pads, ensuring proper orientation.
8. Reinstall the caliper and torque bolts to manufacturer specifications (usually around 79 ft-lbs for caliper bolts).

3. Check Wheel Alignment

Tools Required: Alignment equipment
Sub-steps:
1. After replacing the brake components, have the vehicle's alignment checked.
2. Adjust as necessary to manufacturer specifications.

4. Inspect Suspension Components

Tools Required: Socket set, pry bar
Sub-steps:
1. Visually inspect tie rods, ball joints, and control arms for any play or wear.
2. Replace any worn components as needed, following the manufacturer's torque specifications.
