Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels for safety.

2. Remove Wheels

Use a socket set to loosen lug nuts before lifting the vehicle.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Inspect and Replace Brake Components

A. Brake Rotors

Inspection: Check rotors for warping by measuring runout with a dial indicator.
Replacement: If warped, replace rotors.
- Remove caliper by unbolting it from the bracket.
- Unbolt the rotor and replace it with a new one. Torque to manufacturer specifications (usually around 70-90 ft-lbs).

B. Brake Pads

Inspection: Check the thickness of the brake pads.
Replacement: If worn down, replace with new pads.
- Remove the caliper bracket if necessary.
- Install new pads ensuring they fit snugly. Lubricate backing plates with anti-squeal grease.

4. Reassemble Components

Reinstall the caliper and bracket, ensuring all bolts are torqued to specifications.
Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to proper specifications (typically 80-100 ft-lbs).

5. Final Checks

Recheck brake fluid level and top off if necessary.
Test drive the vehicle to ensure that the issue is resolved.
