Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench.
Remove the negative battery terminal to ensure safety while working on the vehicle.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Use the lug wrench to loosen the lug nuts of the front wheels and lift the vehicle with a jack.
2. Secure the vehicle on jack stands and remove the front wheels.
3. Inspect the brake rotors for warping using a dial indicator; if the runout exceeds manufacturer specifications, replace the rotors.
4. Remove the caliper by unscrewing the mounting bolts and sliding it off the rotor.
5. Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
6. Install the new rotor and secure it with retaining screws if applicable.

3. Inspect and Replace Brake Pads

Sub-steps:
1. With the caliper removed, take out the old brake pads by sliding them out of the caliper bracket.
2. Check the brake pad clips for damage and replace if necessary.
3. Install the new brake pads into the caliper bracket and ensure they are seated properly.
4. Reattach the caliper over the new brake pads and tighten the mounting bolts to manufacturer specifications.

4. Reassemble and Torque Wheels

Sub-steps:
1. Reinstall the front wheels and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and use a torque wrench to tighten the lug nuts to the manufacturer’s specified torque.
