2
Check brake pad thickness and condition for uneven wear or deterioration.
3
Examine suspension components (control arms, tie rods) for wear or damage.
4
Inspect wheel alignment and tire condition for uneven wear or imbalance.
5

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gear including gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front and rear of the vehicle.
Secure the vehicle with jack stands for safety.

3. Inspect and Replace Brake Rotors

Step 1: Remove the wheel using a socket set.
Step 2: Remove the brake caliper by unbolting it from the bracket (use a torque wrench for reinstallation).
Step 3: Remove the brake rotor by unscrewing any retaining screws and sliding it off the hub.
Step 4: Inspect the rotor for warping using a dial indicator. Replace if warped beyond specifications (usually more than 0.002 inches).
Step 5: Install new rotors, ensuring they are clean and free from contaminants.

4. Replace Brake Pads

Step 1: Remove the old brake pads from the caliper bracket.
Step 2: Apply brake grease to the back of the new pads to prevent squeaking.
Step 3: Install new brake pads into the caliper bracket.
Step 4: Reattach the brake caliper over the new pads and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and torque lug nuts to the specified torque value.
Lower the vehicle and remove jack stands.

6. Final Checks

Pump the brake pedal to initialize the calipers and ensure proper brake feel.
Conduct a test drive to confirm the issue has been resolved.
