Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety gear including gloves and goggles.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Check the brake fluid reservoir; if low, add the appropriate type of brake fluid (DOT 4 recommended).
Inspect for any signs of contamination or moisture in the fluid.

3. Bleed the Brakes

Tools Required: Brake bleed kit, wrench
Start with the brake furthest from the master cylinder (usually the rear passenger side).
Attach the brake bleed kit to the bleeder valve and open it.
Have an assistant press the brake pedal several times and hold it down.
Close the bleeder valve before the assistant releases the brake pedal.
Repeat until no air bubbles appear in the fluid.
Move to the next wheel and repeat the process until all brakes are bled.

4. Inspect and Replace Components (if necessary)

Tools Required: Socket set, wrench set
Inspect the brake master cylinder for any leaks or damage; replace if necessary.
Check brake lines for corrosion or pinholes; replace any damaged sections.
Inspect calipers and pads; replace worn components as needed.

5. Test the Brake System

After completing repairs, start the vehicle and pump the brake pedal to restore pressure.
Perform a test drive at low speeds to ensure brakes engage properly.
