Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, caliper tool, and a multimeter (if needed).

2. Wheel and Brake Inspection

Step 1: Loosen the lug nuts on the affected wheel using a lug wrench.
Step 2: Raise the vehicle with a jack and secure it on jack stands.
Step 3: Remove the wheel to gain access to the brake components.
Step 4: Inspect the brake pads for thickness; replace if worn below 3mm.
Step 5: Check the brake rotors for warping or scoring. Use a straightedge to check for warpage; if warped, replace or resurface the rotors.

3. Brake Component Replacement

Step 1: If brake pads are worn, remove the caliper by unbolting it from the bracket.
Step 2: Use a caliper tool to compress the caliper piston and replace the pads.
Step 3: Reinstall the caliper and torque bolts to the manufacturer's specifications (refer to service manual).
Step 4: If rotors are damaged, remove the rotor by unbolting it from the hub and replace with a new rotor.

4. Suspension Check

Step 1: Inspect control arms, bushings, and ball joints for wear or damage.
Step 2: Replace any worn suspension components as necessary.

5. Reassemble and Lower Vehicle

Step 1: Reinstall the wheel and hand-tighten the lug nuts.
Step 2: Lower the vehicle off the jack stands.
Step 3: Torque the lug nuts to the manufacturer's specifications.
