Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent accidental activation of electronic components.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen lug nuts slightly while the wheel is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Inspect Rotors

Check rotors for warping or scoring.
If warped, use a rotor resurfacing tool or replace the rotors if they are below the minimum thickness specification.

B. Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts.
Take out the old brake pads and inspect the caliper piston.
Install new brake pads, ensuring they are properly seated in the caliper bracket.
Reattach the caliper and torque the bolts to the manufacturer's specifications.

4. Examine Suspension and Alignment

Inspect control arms, bushings, and tie rods for wear.
Replace any worn components.
After suspension inspection, perform a wheel alignment to ensure proper tracking.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery.
