2
Check brake pads for thickness and even wear.
3
Examine suspension components (control arms, bushings, etc.) for wear or damage.
4
Inspect wheel alignment and balance.
5

Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a flat surface and use wheel chocks.
Disconnect the battery for safety.

2. Raise the Vehicle

Use a hydraulic jack to lift the front of the vehicle and secure with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Check the rotors for warping using a dial indicator; if warped beyond specifications, replace.
- Remove the caliper by unscrewing the caliper bolts with a wrench. Hang it securely without stressing the brake line.
- Remove the brake pads and then unscrew the rotor from the hub.
- Clean the hub surface and install new rotors, ensuring they are torqued to the manufacturer's specifications (usually around 80-100 lb-ft).

4. Inspect and Replace Brake Pads

Sub-steps:
- Install new brake pads into the caliper bracket.
- Reattach the caliper over the new pads, ensuring it is properly seated and bolts are torqued to specification (typically 30-40 lb-ft).

5. Reassemble and Lower Vehicle

Reinstall the front wheels and torque the lug nuts to the manufacturer’s specifications (usually 80-100 lb-ft).
Lower the vehicle and reconnect the battery.

6. Final Checks

Pump the brake pedal to seat the pads properly.
Conduct a road test to ensure the issue is resolved.
