Solution

1. Preparation

Tools Required: Socket set, brake fluid, vacuum gauge, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves for protection.

2. Check and Refill Brake Fluid

Open the hood and locate the master cylinder reservoir.
If the brake fluid is low, refill it to the recommended level using the correct type of brake fluid (typically DOT 3 or DOT 4).
Inspect the reservoir cap for proper sealing.

3. Inspect and Repair Brake Lines

Visually inspect all brake lines for any signs of corrosion, cracks, or leaks.
If any leaks are found, replace the damaged brake lines with OEM or high-quality aftermarket parts.
Ensure all connections are tightened and sealed appropriately.

4. Test Brake Booster

Disconnect the vacuum hose from the brake booster.
Connect a vacuum gauge to the booster and start the engine.
Verify that the vacuum reading is within manufacturer specifications. If not, replace the brake booster.

5. Inspect Brake Components

Remove the wheels to access the brake pads and rotors.
Measure the thickness of the brake pads; replace if they are below the minimum specification.
Inspect the rotors for warping or scoring. Resurface or replace as necessary.
Reassemble the wheels and lower the vehicle.
