Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, brake fluid, micrometer.
Ensure the vehicle is parked on a level surface and turn off the ignition. Disconnect the battery if necessary for safety.

2. Replace Brake Pads

Sub-steps:
1. Loosen the lug nuts on the wheel corresponding to the affected brake.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel and inspect the brake pads for wear.
4. Remove the caliper bolts using a socket set, then detach the caliper from the rotor.
5. Replace worn brake pads with new ones, ensuring they are properly aligned.
6. Reattach the caliper and torque the bolts to the manufacturer's specifications (usually around 25-30 lb-ft).

3. Bleed Brake System

Sub-steps:
1. Refill the brake fluid reservoir with fresh brake fluid as needed.
2. Start at the furthest wheel from the master cylinder; use a brake bleeder kit.
3. Open the bleeder valve and have an assistant press the brake pedal.
4. Close the valve before the pedal is released to prevent air from entering.
5. Repeat until no air bubbles are visible in the fluid, moving to the next closest wheel.

4. Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are below the minimum thickness, use the micrometer to confirm.
2. Remove the caliper as described above and hang it securely.
3. Remove the rotor-retaining screws if present, then slide the rotor off the hub.
4. Install the new rotor, ensuring it is seated properly. Reinstall any screws.
5. Reattach the caliper and torque the bolts to specifications.
