Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secured with jack stands.
Wear safety gloves and goggles.

2. Check and Top Off Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Check the fluid level against the "MIN" and "MAX" marks.
3. If low, add the recommended brake fluid (DOT 3 or DOT 4) to the proper level.
Tools Required: Brake fluid

3. Bleed the Brake System

Sub-steps:
1. Begin at the wheel farthest from the master cylinder (usually the right rear).
2. Attach a clear hose to the bleeder valve on the brake caliper.
3. Have an assistant pump the brake pedal several times and then hold it down.
4. Open the bleeder valve to release air and fluid, then close it before the pedal is released.
5. Repeat until no air bubbles are visible in the fluid.
6. Move to the next wheel and repeat the process until all wheels are bled.
Tools Required: Brake bleeder kit, wrench for bleeder valve

4. Inspect and Replace Components

Sub-steps:
1. Inspect brake pads and rotors for wear. Replace if they are worn beyond specifications.
2. If the brake lines are found to be damaged or corroded, replace them.
3. Check the brake booster for proper operation and replace if defective.
Tools Required: Socket set, torque wrench, brake pad spreader
