Solution

1. Preparation

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

2. Inspect and Replace Brake Rotors

Remove the wheel:
- Use a jack to lift the front of the car and secure it on jack stands.
- Remove the lug nuts using a socket and ratchet, then take off the wheel.
- Tools Required: Jack, jack stands, socket set.
Check rotor condition:
- Visually inspect the rotors for warping or grooves; use a micrometer to measure rotor thickness.
- If warped beyond specifications (typically more than 0.003 inches), proceed to replace them.
Remove the caliper:
- Unbolt the brake caliper using the appropriate socket.
- Suspend the caliper using a wire to avoid straining the brake line.
- Tools Required: Socket set, wire.
Remove the rotor:
- Take off any retaining screws if applicable.
- Slide the rotor off the hub.
Install new rotor:
- Clean the hub surface and install the new rotor.
- Reattach retaining screws if applicable.

3. Replace Brake Pads

Remove old brake pads:
- Slide the brake pads out of the caliper bracket.
- Note the orientation for installation of the new pads.
Install new brake pads:
- Apply brake grease to the backing of the new pads.
- Insert the new pads into the caliper bracket.
Reattach the caliper:
- Position the caliper over the new pads and bolt it back into place.
- Tools Required: Torque wrench (torque to manufacturer specifications).

4. Reassemble and Test

Reinstall the wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value.
Test the brakes:
- Start the vehicle and pump the brakes to set the pads against the rotors.
- Conduct a test drive to ensure the issue is resolved.
