Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Rotors

Tools Required: Jack, jack stands, tire iron, torque wrench, socket set, runout gauge.
Sub-steps:
1. Jack up the vehicle and secure it with jack stands.
2. Remove the front wheels using the tire iron.
3. Inspect the brake rotors for warping using a runout gauge; replace if warping exceeds specifications.
4. If replacing, remove caliper bolts and slide caliper off the rotor.
5. Remove the rotor by unscrewing the retaining screws (if equipped) and slide it off the hub.
6. Install the new rotor, ensuring proper alignment.
7. Reattach the caliper and torque bolts to manufacturer specifications.

3. Inspect and Replace Brake Pads

Tools Required: Brake pad spreader tool.
Sub-steps:
1. Remove the caliper as described in the previous step.
2. Remove the old brake pads from the caliper bracket.
3. Inspect the caliper slides for smooth movement, lubricate if necessary.
4. Install new brake pads, ensuring they are seated properly.
5. Reinstall the caliper over the new pads and torque the bolts to specifications.

4. Check Suspension Components

Tools Required: Visual inspection tools.
Sub-steps:
1. Visually inspect tie rods, control arms, and ball joints for wear.
2. Wiggle each component; any noticeable play indicates replacement is needed.
3. Replace any worn components and ensure everything is tightened to the correct torque values.

5. Wheel Alignment and Balance

Tools Required: Alignment and balancing equipment (typically done at a shop).
Sub-steps:
1. After all repairs, take the vehicle to a professional alignment shop.
2. Ensure wheels are balanced and aligned according to manufacturer specifications.
