Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Gather tools: jack, jack stands, wrench set, brake fluid, brake bleeder kit.

2. Check and Refill Brake Fluid

Sub-steps:
1. Locate the master cylinder reservoir under the hood.
2. Check the brake fluid level; if low, refill with the recommended brake fluid type (DOT 3 or DOT 4).
3. Ensure the cap is securely fastened after refilling.

3. Bleed Brake Lines

Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually the right rear).
2. Attach brake bleeder kit to the bleeder valve on the brake caliper.
3. Have an assistant press the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and brake fluid; close the valve before the assistant releases the pedal.
5. Repeat until no air bubbles are visible in the fluid.
6. Repeat for each brake caliper in the correct order (right rear, left rear, right front, left front).

4. Inspect Brake Booster

Sub-steps:
1. Check the brake booster for vacuum leaks by inspecting the vacuum hose and connections.
2. If the booster is faulty, replace it following manufacturer guidelines.

5. Reassemble and Test

Sub-steps:
1. Reinstall any removed components or covers.
2. Lower the vehicle and perform a test drive to check for proper brake feel and response.
