Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Engage the parking brake and place wheel chocks behind the rear wheels.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rag
Check the brake fluid level and condition.
If the fluid is low or contaminated, drain the old fluid from the master cylinder and refill with new brake fluid according to manufacturer specifications.

3. Inspect Brake Lines and Components

Tools Required: Wrench set, socket set
Visually inspect the brake lines for leaks, corrosion, or damage.
Tighten any loose connections and replace any damaged lines or components as necessary.

4. Bleed the Brakes

Tools Required: Brake bleeder kit, clear tubing
Start at the wheel furthest from the master cylinder (usually the rear passenger side).
Attach the clear tubing to the bleeder valve and open it while a helper presses the brake pedal.
Close the valve before the pedal reaches the floor and repeat until no air bubbles are present.
Continue this process for all four brakes.

5. Inspect and Replace Brake Booster (if needed)

Tools Required: Socket set, brake booster replacement part
Check the brake booster for vacuum leaks or failures.
If defective, remove the brake booster from the vehicle and replace it with a new unit.
