Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Tools Required: Socket set, brake fluid, vacuum pump, OBD-II scanner, jack and jack stands.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Remove the cap and check the fluid level. If low, fill it with the recommended brake fluid type.
Inspect for any signs of contamination or debris in the fluid.

3. Inspect Brake Booster

Disconnect the vacuum line from the brake booster.
Use a vacuum pump to apply vacuum to the brake booster. If the vacuum holds, the booster is likely functioning correctly. If it doesn't hold, replace the brake booster.

4. Inspect Brake Lines and Components

Visually inspect all brake lines for any leaks, corrosion, or damage.
Tighten any loose fittings and replace any damaged lines or components as necessary.

5. Reassemble and Test

Reconnect any vacuum lines and ensure all components are securely fastened.
Refill the brake fluid if it was low and replace the master cylinder cap.
Start the vehicle and pump the brake pedal to check for improved responsiveness.
