Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, runout gauge, OBD-II scanner.

2. Inspect and Replace Brake Rotors

Step 2.1: Remove the wheel.
- Use a lug wrench to loosen the lug nuts before lifting the vehicle.
- Raise the vehicle with a jack and secure it on jack stands.
Step 2.2: Remove the brake caliper.
- Unbolt the caliper using the appropriate socket.
- Carefully hang the caliper using a bungee cord to avoid straining the brake line.
Step 2.3: Remove the brake rotor.
- If necessary, remove the retaining screws or clips holding the rotor in place.
- Slide the rotor off the hub.
Step 2.4: Check the rotor for warping.
- Use a runout gauge to measure any warping. If the rotor exceeds manufacturer specifications, replace it.
Step 2.5: Install new rotors.
- Clean the new rotors with brake cleaner to remove any protective coating.
- Slide the new rotor onto the hub and secure it with screws or clips.

3. Inspect and Replace Brake Pads

Step 3.1: Check brake pads for wear.
- If the pads are worn unevenly, replace them.
Step 3.2: Install new brake pads.
- Apply brake grease to the backing of the new pads.
- Insert the new pads into the caliper bracket.

4. Reassemble Braking Components

Step 4.1: Reinstall the brake caliper.
- Position the caliper over the new pads and secure it with bolts.
- Torque the caliper bolts to the manufacturer’s specifications.
Step 4.2: Reinstall the wheel.
- Place the wheel back onto the hub, hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the specified value.

5. Test Drive

After the installation, perform a test drive to ensure the issue has been resolved.
