Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Brake fluid tester
- Socket set
- Torque wrench
- Brake cleaner
Safety Warnings:
- Ensure the vehicle is on a level surface and securely supported with jack stands.

2. Replace Brake Pads

Sub-steps:
1. Remove the wheel using the appropriate socket size.
2. Remove the caliper bolts using a socket wrench, then carefully lift the caliper off the rotor.
3. Remove old brake pads from the caliper bracket.
4. Install new brake pads in the caliper bracket, ensuring they are properly aligned.
5. Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
6. Repeat on the other side if necessary.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. With the caliper removed, check the rotor for scoring or excessive wear.
2. If replacement is needed, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
3. Install the new rotor and secure it with screws, torqueing to specifications.
4. Reinstall the caliper and pads as outlined in the previous step.

4. Bleed Brake System

Sub-steps:
1. Locate the brake bleeder valve on each caliper.
2. Attach a clear hose to the bleeder valve and place the other end in a container.
3. Have an assistant pump the brake pedal several times, and then hold it down.
4. Open the bleeder valve to allow brake fluid to escape until no air bubbles are present, then close the valve.
5. Repeat this process for each wheel, starting from the wheel farthest from the master cylinder.
6. Check and top up the brake fluid reservoir as necessary.
