Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Wear safety goggles and gloves.

2. Remove Front Wheels

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and securely place it on jack stands.
3. Remove the lug nuts completely and take off the front wheels.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, brake cleaner
Sub-steps:
1. Remove the caliper bracket by loosening the bolts; support the caliper to avoid strain on the brake line.
2. Take off the brake pads and measure rotor thickness with a micrometer.
3. If rotors are warped (beyond acceptable tolerance, usually 0.002 inches), remove them and replace with new ones.
4. Clean the hub surface and new rotors using brake cleaner before installing.

4. Install New Brake Pads

Tools Required: Torque wrench
Sub-steps:
1. Install new brake pads into the caliper bracket.
2. Reattach the caliper bracket and torque the bolts to manufacturer specifications (usually around 80 ft-lbs).
3. Ensure that the caliper moves freely and is not binding.

5. Reassemble and Test

Reinstall the front wheels and torque the lug nuts in a star pattern to specifications (around 76 ft-lbs).
Lower the vehicle from the jack stands.
Test the brakes gently to ensure proper function.
