Solution

1. Preparation

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

2. Remove Wheels

Using a lug wrench, loosen the lug nuts on the front wheels.
Raise the vehicle using a jack and support it with jack stands.
Remove the wheels to gain access to the braking system.

3. Inspect and Replace Brake Rotors (if warped)

Remove the caliper by unbolting it from the bracket using a socket set.
- Tools Required: Socket set, torque wrench.
Secure the caliper using a bungee cord to avoid straining brake lines.
Remove the brake pads from the caliper bracket.
Unbolt and remove the brake rotor from the hub.
Measure the rotor thickness and check for warping. If warped, replace with new rotors.
Parts Required: New brake rotors (if needed).

4. Install New Brake Pads

Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads into the caliper bracket.
Reinstall the rotor and caliper, ensuring all bolts are torqued to manufacturer specifications.

5. Reassemble and Check Suspension

Reinstall the wheels and torque the lug nuts to the specified value.
Lower the vehicle and inspect suspension components for any signs of wear or damage.
If suspension components are damaged, replace them as necessary.
