Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and safely engage the parking brake.
Disconnect the battery if necessary for brake component work.

2. Check and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in all tires.
Inflate or deflate tires to match the manufacturer’s recommended pressure levels.

3. Inspect and Replace Brake Pads

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake pad spreader.
Loosen and remove the wheel using a lug wrench.
Remove the brake caliper by unscrewing the caliper bolts.
Slide the old brake pads out of the caliper bracket.
Inspect the caliper for any sticking or damage; replace if necessary.
Install new brake pads, ensuring they are correctly seated in the caliper bracket.
Reinstall the caliper and torque bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

4. Perform Wheel Alignment

Tools Required: Alignment rack or alignment kit.
Follow the vehicle manufacturer's specifications for alignment adjustments.
Adjust camber, caster, and toe as necessary to ensure alignment is within specified tolerances.

5. Inspect and Replace Suspension Components (if necessary)

Check for worn bushings, ball joints, or tie rods that may affect braking performance.
Replace any worn components as needed to restore proper alignment and handling.
