Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and wear safety glasses.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure with jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect the brake pads for wear. If they are below the minimum thickness, remove them.
4. Use a socket set to remove the caliper bolts.
5. Carefully slide the caliper off, supporting it with a bungee cord or similar to avoid stress on the brake line.
6. Replace the old brake pads with new ones, ensuring they are properly seated.
7. Reinstall the caliper and torque the bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).

3. Inspect and Resurface/Replace Brake Rotors

Sub-steps:
1. While the caliper is removed, check the brake rotor for any visible damage.
2. If the rotor is warped or excessively worn, remove it by loosening the retaining screws and sliding it off the hub.
3. If resurfacing, use a brake lathe; if replacing, install a new rotor.
4. Ensure the rotor is clean and free of debris before reinstalling it.

4. Check Brake Fluid and Lines

Sub-steps:
1. Inspect the brake lines for any signs of cracking or leaks.
2. If the brake fluid is dark or contaminated, flush the system. To do this:
  - Connect a brake bleeder kit to the brake caliper.
  - Open the bleeder valve and allow old fluid to drain into a container while adding new fluid to the master cylinder.
  - Repeat for all corners until clean fluid runs out of each caliper.
3. Close all bleeder valves and check fluid level in the master cylinder, topping off as needed.

5. Brake Booster Function Check

Sub-steps:
1. Reconnect the battery.
2. Start the engine and check if the brake pedal feels firm when pressed.
3. If the pedal does not drop slightly, the brake booster may need replacement.
