Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection

Tools Required: Tire pressure gauge
Check the tire pressure on both front wheels and adjust to the manufacturer's specifications.
Inspect the tires for uneven wear patterns and replace if necessary.

3. Brake Pad and Caliper Inspection

Tools Required: Jack and jack stands, lug wrench, torque wrench
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect brake pads for uneven wear; replace if one side is significantly more worn.
Check brake calipers for any signs of sticking; clean or replace as needed.

4. Suspension Inspection

Tools Required: Socket set, torque wrench
Visually inspect all suspension components (control arms, bushings, tie rods) for any signs of wear or damage.
If any parts are damaged, replace them accordingly and ensure all bolts are torqued to specifications.

5. Brake Fluid Check

Tools Required: Brake fluid tester
Inspect the brake fluid level in the master cylinder reservoir.
If brake fluid is low, check for leaks in the brake lines and around the calipers; top off with the recommended brake fluid type.
