Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the brake system.

2. Inspect Brake Pads and Rotors

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the wheel using a lug wrench.
2. Inspect the brake pads for thickness; replace if they are below the manufacturer’s specification.
3. Use a dial indicator to measure rotor runout; if warped beyond specifications, replace the rotors.
4. Clean the rotor surface with brake cleaner if no significant damage is found.

3. Check Suspension Components

Tools Required: Pry bar, socket set.
Sub-steps:
1. Visually inspect control arms, bushings, and tie rods for wear or damage.
2. Use a pry bar to check for play in the ball joints and wheel bearings.
3. Replace any worn components, ensuring proper torque settings.

4. Brake Fluid Inspection

Tools Required: Brake fluid tester (optional), funnel.
Sub-steps:
1. Check the brake fluid reservoir for level; top off if low with manufacturer-recommended fluid.
2. Inspect fluid condition; if contaminated, perform a brake fluid flush.

5. Reassemble and Torque

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
3. Reconnect the battery.
