Diagnostic Steps

1
Inspect brake rotors for warping by measuring thickness with a dial indicator.
2
Check brake pad condition for uneven wear or contamination.
3
Examine suspension components (e.g., control arms, bushings) for wear or damage.
4
Inspect wheel bearings for play or roughness.
5
Verify tire balance and alignment.

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspection:
- Measure rotor thickness using a micrometer to check for warpage.
- Look for cracks or excessive wear.
Replacement:
- If warped, remove the caliper by loosening the mounting bolts, and detach it from the rotor.
- Remove the rotor by unscrewing the retaining screws (if applicable).
- Install the new rotor and reattach the caliper, ensuring to torque the bolts to manufacturer specifications (typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Pads

Check the brake pads for wear; replace if they are worn down to the wear indicator or uneven.
Remove the caliper bracket if necessary and replace the pads.
Apply anti-squeal lubricant on the back of the pads and reinstall the caliper.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 130-150 ft-lbs).
Reconnect the battery and perform a test drive to ensure the issue is resolved.
