Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal for safety.

2. Check Brake Fluid

Remove the master cylinder cap.
Inspect brake fluid level; it should be within the recommended range.
If low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

3. Inspect Brake Booster

Locate the brake booster, typically mounted on the firewall.
Check for any signs of physical damage, rust, or corrosion.
Use a vacuum gauge to test the brake booster’s vacuum; it should hold steady vacuum without significant drops.

4. Replace Brake Booster (if faulty)

Remove the master cylinder by disconnecting the brake lines and unbolting it from the booster.
Unbolt the brake booster from the firewall (typically 4-6 bolts).
Disconnect the vacuum line from the booster.
Install the new brake booster by reversing the removal steps, ensuring all bolts are torqued to manufacturer specifications (check service manual for torque values).
Reconnect the vacuum line and master cylinder.

5. Bleed Brake System

After reassembly, bleed the brake system to remove any air using a two-person method or a brake bleeder tool.
Start with the wheel furthest from the master cylinder (usually the rear passenger side) and work towards the closest (front driver side).
