Solution

1. Preparation

Tools Required: Wrench set, brake fluid, jack and jack stands, brake bleeder kit.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before working on it.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Clean the area around the cap to prevent contamination.
Remove the cap and check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Inspect and Repair Leaks

Visually inspect all brake lines and components for signs of leakage.
If a leak is found, replace the damaged brake line or component.
- Sub-steps:
  - Use a wrench to loosen and remove the damaged line.
  - Install a new brake line, ensuring all connections are tight.
  - Bleed the brake system after replacement to remove air.

4. Bleed the Brakes

Begin by having an assistant press the brake pedal while you open the bleeder valve on the farthest wheel from the master cylinder (usually the rear passenger side).
Allow fluid to flow until there are no bubbles, then close the valve.
Repeat the process for the remaining wheels in the order: rear passenger, rear driver, front passenger, front driver.
Check fluid level and add as necessary throughout the bleeding process.

5. Test the Braking System

After repairs and bleeding, press the brake pedal to ensure it feels firm and does not sink.
Conduct a test drive at low speeds to confirm proper braking function.
